Powder coating removal from aluminium


When it comes to metal painting, there are various ways to do it, some more prevalent than others. In Aluminum’s case- powder coating is one of the most used ways of coloring. A colored powder is sprayed on the metal when it is extremely hot, which results in a very strong second bond that ultimately leads to long lasting color.

Sometimes people don’t need the metal color anymore and want their object back in the original color, in which case one can follow the following steps to remove the color-

STEP 1: Set up a location outside home to hang the object so that it is accessible in all the areas. You can use your garage or work station for this work.

STEP 2: If there are any areas that you don’t want to change color of, cover them with paper bags and tape them all around very well so that they stay intact.

STEP 3: Use an industrial strength gasket remover to remove the powder color by spraying it all over. Leave it on for 15-20 minutes, by this time you shall see the powder coating bubbling and peeling down.

STEP 4: Clean the object with a dry rag and if you’re still able to see the color at some places, repeat the process.

Safety precautions:
Wear thick long-sleeved clothing, gloves, safety goggles and a respiratory mask since the gasket remover is pretty poisonous.
Discard all the rugs and bags used in the process.

What causes metals to corrode?



Ever seen those dreary red vehicular bridges or metal structures leading to water tanks, creaky gates, fences or handles? The most common example of corrosion that we see in our everyday lives is rust – corrosion of the iron metal. This redness indeed is a typical representation of the phenomenon of ‘corrosion of metals’. Corrosion is when the metal quality has deteriorated.

What causes corrosion of metals?

Corrosion in metals is an electrochemical process; it is part chemical and part electrical. Positively & negatively charged ions from the metal result into a chemical called ‘iron hydroxide’ when they come in contact with water. When both oxygen and moisture work their wrath on the metal, it causes the metal to corrode. It will continue to cause the reaction leaving back nothing but say, a pile of rust (in case of iron) as long as the process continues.

Which metals are prone to corrosion?

In the metal family, magnesium, aluminum, iron, zinc, brass, copper, bronze and tin have higher reactivity so they easily corrode. Rust on steel, greening of copper or tarnish on silver/brass is a common phenomenon that we see every day around us. It also represents danger to human lives as its impact can cause injury.

What are the typical causes of corrosion?

·         Improperly maintained metal
·         Use of low quality metal
·         Ignorance towards maintenance of structural issues such as plumbing problems, leaky areas/roofs, stagnant water, and foundation issues of the building/structure, etc.

Does this mean all metals corrode? No, some metals rarely corrode. This group of metals which are less reactive, also known as ‘Noble Metals’ are metals that can be found in nature in their purest form - rhodium, palladium, silver, platinum, and gold are some examples of metals that are much less reactive than others; thus more expensive!
Understanding of the environmental conditions and metal properties and implementing this understanding into your design structure or foundation is an effective preventive measure against metal corrosion.

How is Scrap Metal Processed


In an era of recycling, it is imperative to have knowledge of recycling process in order to take better decisions of the tools and methods of recycling. The recycling process dealt with here in particular, is scrap metal. 

A scrap metal processing yard where one gives away his or her scrap metal for recycling, chiefly categorize the metals into ferrous and non-ferrous metals. Ferrous (from Latin ferrum, meaning "iron") metals comprised of iron and steel (an iron alloy). Copper, aluminium, brass et al., are called non-ferrous metals.

Scrap metal processing in part entails separation of these types of metals from each other using magnetized tools. A number of wrecking yards allow people to purchase scrap metals for specific purposes. Such a sale occurs only after due separation of the metals. This makes for easier identification of the metal by an interested buyer.

The primary basis of the sale of metals by the wrecking yards is the weight of the scrap metal being sold. Quality of the metal is really not that important in such a scenario. This is because the main concern of the yards is what the metalworks factories give them for selling metal. Metalworks factories purchase metals on the basis of weight.

After proper separation and sorting into suitable divisions, the scrap metal is subject to a number of processes which include cutting, shredding, molding and turn into metal cubes. The metal cubes are then purchased by the metalworks factories that melt the metals for the manufacture of new products.

Methods of Recycling Non-ferrous Metals



Conscious efforts towards sustainability have led to the recycling of even non-ferrous metals like aluminum, copper, nickel, silver, and tin. These metals retain their original properties even after undergoing recycling repeatedly. As they are found mixed with liquids and solids, extracting and purifying them before recycling can be a complex task. However, recycling is cheaper than mining metals and saves up to 95% of energy costs.

Three methods widely used to recycle non-ferrous metals are:

Electrowinning: Electrowinning, also known as electroextraction, is a relatively simpler procedure of extracting metals, which dissolves them using electricity. If non-ferrous metals are to be extracted for recycling, the procedure involves the metal in any form of waste to be put in a liquid solution, to dissolve it into the liquid a state known as leaching or leachate and then submerging it using cathodes. Hence, non-ferrous metals like copper, nickel, silver, and tin are recycled for further use.

Precipitation: Another widely used method for recycling non-ferrous metals from aqueous solutions is precipitation. It includes two metal removal sub-methods known as co-precipitation and adsorption. The end-result metal is called precipitate and the chemical that causes it to precipitate is called precipitant, which is mostly sodium and calcium hydroxides or oxides used to increase the pH.

Metal Sensors: Metal sensors are widely being used in sorting and extracting non-ferrous metals from scrap found in vehicles or e-waste. The method might falter as non-ferrous metals of similar densities can’t be separated from each other using gravimetric techniques which ultimately require human observation and intervention.

What exactly is scrap metal?

Metal is present in most objects we see around us - food storage boxes, houses, vehicles, accessories, computers, mobile phones - a component that's found in various things, big or small. When these objects are old and ready to be discarded or demolished, the metal that remains becomes scrap metal, which can be melted and recycled to produce new useful products for consumers.

Many consumers, individuals or  business organisations, actively participate in recycling discarded metals by bringing large amounts of scrap metal to the scrap yards which also rewards them with money in return.

Some sources of scrap metal are:

Construction Waste: 

Lots of metal like aluminium siding, steel beams and copper pipes go into constructing houses and other buildings. When old buildings are demolished, the leftover metal materials can be used for new construction.

Industrial Waste: 

Factories, manufacturers and other mechanic shops discard heaps of metal waste. After metal sheets are cut out, the remaining material becomes scrap which can be recycled for new products.

Auto Parts: 

Large number of old/damaged automobiles and their parts are discarded, from which the metal parts can be broken down, recycled and reused as metal scraps.

Consumer Goods: 

Our houses are loaded with metal scraps right from household appliances  to steel cutlery, cans, can openers, aluminium foil, electronics like computers and televisions and furnishings. At scrapyards, these metals are recycled to make other goods.

If you plan on recycling metals, the simplest way is to gather your old household items and bring them to scrapyard to be recycled and reused.

Difference Between Ferrous and Non-Ferrous Scrap Metal


While buying and selling scrap material, have you ever wondered “What is the difference between ferrous and non-ferrous materials?” If you have, read on to learn more.

Ferrous metals like mild steel, stainless steel, cast iron, wrought iron and carbon steel contain irons which are used for their strength and durability. They are used in making industrial containers, construction of buildings, pipes, automobiles and rails for railroads and hardware tools like knives, used at home.

Most ferrous metals except for wrought iron and stainless steel are prone to rusting because of the use of carbon to create them. They also have magnetic properties and are used in creating electrical appliances like refrigerators and large motors. The most recycled materials in the world are indeed ferrous metals.

Non-ferrous metals include tin, lead, copper, brass, aluminium and zinc. These metals are strong, more malleable and light weight than ferrous metals and are used largely in the canning industry and aircrafts.

Since they don’t contain iron, they resist rusting and are used in water pipes, road signs, gutters and roofing. Their non-magnetic factor works in electrical wiring and small electronics. Also, aluminium is the third most recycled material while other non-ferrous metals like brass, lead and copper are scarce.

Those wanting to sell the metal must know that ferrous metals are found in good number; hence the prices tend to be lower than non-ferrous metals with minor rises or drops in the pricing. Other than aluminium, prices of non-ferrous metals can highly fluctuate.

Aluminium Recycling

The act of recycling metals has been in practice for a very long time as aluminium can be reprocessed and reformed an endless number of times without affecting its quality.

Recycling aluminium takes just 5% of energy and all of its properties remain as good as new which add to its demand in the scrap industry. The metal can be used in the manufacturing of various products e.g. cars, aeroplanes, window frames, food packaging and many more.

There are five stages involved in the process of recycling aluminium:

1. Collecting:

 Aluminium waste material in the form of aerosols, drink cans and foil trays can be collected from houses or waste banks where they are mixed with other food and drink packaging. Some waste management councils also collect aluminium waste like foils and cans separately.

2. Sorting: 

After collection, the recyclable metals are taken to local waste transfer stations where, with the use of magnets, they are sorted into groups of steel and aluminium items that arecompressed into bales.

3. Reprocess:

 After the metals are compressed into bales they are taken to a reprocessing plant where they undergo the stages of shredding, decoating, melting and casting. In the last stage the molten metal is cast into huge ingots.

4. Rolling:

 The ingots are sent to rolling mill that is then rolled out to create sheet aluminium which can then be used to make new packaging.

5. Conversion:

 The aluminium sheets are then fit to undergo conversion to produce a variety of packaging items.

A Guide to Identify Metals





If you are new to this world of scrap metal recycling, you are surely prone to get confused between steel, iron, tin and aluminium. This unfamiliarity and inability to identify these metals can be quite overwhelming. But there is nothing for you to worry about. This guide will assist you in identifying the various kinds of metals out there.

As a matter of fact, there are various tests you can perform in order to classify various kinds of metals. These tests include the following:

1.Magnet Test


This is by far the simplest way to classify and identify the metal. Getting an ordinary magnet is all you need and in case the metal contains iron, it would get attracted to magnet. These are ferrous metals. Scrap iron will pass this test. However, scrap brass or aluminium will not be responding to magnet as they are non-ferrous in nature.

2.Identification by Means of Colour


Colour of the metal can help you in identifying the chemical makeup of the metal. In case the metal is red in colour, it could be copper or even red brass. Similarly, golden coloured metal could be brass.

3.Identification by Means of Weight


You can also classify metals on the basis of their weight. For example, a lightweight metal could me aluminium and likewise, lead and iron metals would be heavy in weight.

4.Hardness Test 


If the metals are soft, they could be copper; however, metals like steel and iron are quite hard and are break resistant. The metal which is quite easy to bend is aluminium.

5.Professional Help 


If you are still unable to classify the metal, it would be best to seek help from professionals. They can assist you in classifying the metals through their scientific tests.
