Aluminium coil: Know features, uses, grades and more

If you are looking to source aluminium coil you first need to know how to determine the quality of the coils. This depends on several factors like grade of aluminium, formability, ease of machining, etc. Then you need to look for coil suppliers who are reputed for selling quality coils in the market.

This article explains the uses and applications of aluminium coil in today’s industrial setting.

What is an aluminium coil?

Aluminium coils are sheets of flattened aluminium rolled into a coil. The width of the aluminium sheet is much greater than its thickness. These coils appear to be hollow cylinders with thick outer edges. Since individual aluminium sheets are difficult to store and carry, industries gradually adopted coiling of aluminium which made it easy to store and transport.

How is aluminium coil manufactured?

Aluminium coil manufacturers source aluminium slabs for producing aluminium coils. The ends of these slabs are sawn off and scalped before beginning the coiling process. Given below are the steps in manufacturing aluminium coil:

Step 1 – The scalped slab is placed inside the preheating furnace to be preheated and made ready for the hot rolling process.

Step 2 – The heated slab is put through the hot rolling machine and hot rolled back and forth several times to turn them into sheets with a certain thickness

Step 3 – The hot rolled aluminium sheet is then sent to cold rolling.

Step 4 –  The cold rolled steel is then sent to the annealing furnace to adjust the properties of the coil to match the customer requirements.

What are the uses of aluminium coil?

Aluminium coil is used in different industries mainly for manufacturing and construction. It is lightweight and sturdy making it perfect for numerous industrial tasks. Here are some of the aluminium coil uses in various industries:

• Automotive industry: Aluminium coils are used to make the body of vehicles like campers. The lightweight nature, durability and the non-corrosive property make it an excellent vehicle body component.
• Modern building construction: Today’s architecture features gentle curves and geometric structures. Any application requiring a unique shape will rely on bending processes. Aluminium is ductile and at the right temperatures can be bent into desired shapes.
• Electronic components: Numerous electronic manufacturers use aluminium to house their circuitry. Aluminium’s resistance to corrosion adds durability to the wires in the circuit.
• Food containers: Aluminium tin cans are common to preserve canned food items. Its resistance to corrosion keeps the food fresh for a longer time.

What are the different grades of aluminium coils?

There are different aluminium coil grades depending on the aluminium coil material/alloy used in the rolling process. The aluminium coil price and the purpose it will be used for will determine the grade to be chosen.

There are two main classifications of aluminium alloys: wrought aluminium  and cast  Aluminium.

These are further divided into multiple categories based on the main alloying element and their mechanical and thermal treatment response. Wrought iron is divided into separate series from Series to Series . Under each series there are different alloys that are assigned a unique grade.

Here are a few examples of the common aluminium grades found in the market Aluminium

Aluminium is the purest form of aluminium. Made with 99% minimum purity, it features excellent workability and ductility. This metal does not harden when worked or heated compared to other metals. It highlights corrosion resistance and weldability making it a versatile metal. It is a great choice for challenging forming operations and in applications that require thermal conductivity. The versatility of Aluminum allows it to be shaped into different products like chemical equipment, fin stock, dials, railroad tank cars, and nameplates in the manufacturing industry.

Aluminium

Aluminium is the most used form of aluminium. This metal is made of 98.6% aluminium mixed with 1.2% manganese and 0.12% copper to increase its strength. It is readily weldable but does not have the corrosion resistance of . It is an economical alternative as the Aluminum coil prices are lower compared to other aluminium alloys. Since it is a general-purpose alloy it is found in cooking utensils and pot lids, but it cannot handle high temperatures like those found in an oven or grill.

Aluminium

Often called ‘The Workhorse Aluminium’, aluminum has a remarkable corrosion resistance. Its high heat welding properties as well as its strength allow it to be used for products that experience a high level of wear and tear. It has excellent formability and can be used in bending, deep drawing, and stamping.

Aluminium coil vs steel coil

Aluminium coils are flattened aluminium sheets rolled into coils while steel coils are flattened steel sheet rolled into coils. Hot rolled and cold rolled steel coils are two main steel coil types available in the market. Like aluminium coils, steel coil uses include manufacturing automotive parts and electronic components. Both these metals are known for their ductility and affordability.

Aluminised steel coil

Aluminium coated steel coil is called aluminised steel coil. Some people commit an error calling it aluminium steel coil. It is nothing but steel coil that has been coated with aluminium. Aluminium coated steel coil cannot corrode due to the protective layer of aluminium. Here are some features of aluminised steel coil:

• Strength of steel plus the corrosion resistance of aluminium
• High-temperature resistance
• Low thermal expansion
• Formability that allows rolling, folding, bending, and corrugating
