If you are looking for aluminum coils, you first need to know how to determine the quality of the coils. This depends on several factors such as the grade of aluminum, formability, ease of processing, etc. Then, you need to look for coil suppliers who are well-known in the market for selling quality coils.
This article explains the uses and applications of aluminum coils in today's industrial environment.
What is aluminum coil?
Aluminum coils are flat sheets of aluminum that are rolled into a coil. The width of the aluminum sheet is much greater than its thickness. These coils look like hollow cylinders with thicker outer edges. Since single sheets of aluminum are difficult to store and transport, various industries have gradually adopted aluminum coils for easier storage and transportation.
How is aluminum coil made?
Aluminum coil manufacturers purchase aluminum sheets to produce aluminum coils. Before starting the coiling process, the ends of these sheets are sawed off and peeled. Here are the steps to make aluminum coils:
Step 1 - The peeled slabs are placed in a preheating furnace for preheating in preparation for the hot rolling process.
Step 2 – The heated slab is placed in a hot rolling mill and hot rolled several times back and forth to produce a sheet of a certain thickness
Step 3 – The hot rolled aluminum sheet is then sent for cold rolling.
Step 4 – The cold rolled steel is then sent to an annealing furnace to adjust the properties of the coil to meet customer requirements.
What are the uses of aluminum coil?
Aluminum coil is mainly used in different industries such as manufacturing and construction. It is lightweight and strong, which makes it ideal for a variety of industrial tasks. Here are some of the uses of aluminum coil in various industries:
Automotive Industry: Aluminum coil is used to make the body of vehicles such as campers. Its light weight, durability and non-corrosive properties make it an excellent body component.
Modern Building Construction: Today's buildings have gentle curves and geometric structures. Any application that requires a unique shape will rely on the bending process. Aluminum is ductile and can be bent into the desired shape at the right temperature.
Electronic Components: Many electronic manufacturers use aluminum to encapsulate circuits. Aluminum's corrosion resistance increases the durability of the wires in the circuits.
Food Containers: Aluminum cans are often used to preserve canned food. Its corrosion resistance keeps food fresher for longer.
What are the different grades of aluminum coil?
Aluminum coil has different grades depending on the material/alloy used in the rolling process. The price and purpose of the aluminum coil will determine the grade to choose.
There are two main classifications of aluminum alloys: wrought aluminum and cast aluminum.
These alloys are further divided into multiple categories based on the main alloying elements and their mechanical and heat treatment reactions. Wrought iron is divided into separate series from the 1000 series to the 8000 series. There are different alloys under each series and are assigned unique grades.
Here are a few examples of common aluminum grades in the market
1100 Aluminum
1100 aluminum is the purest aluminum. With a purity of at least 99%, it has excellent machinability and ductility. Compared to other metals, this metal does not harden when it is worked or heated. It has excellent corrosion resistance and weldability, making it a very versatile metal. It is an excellent choice for challenging forming operations and applications that require thermal conductivity. The versatility of 1100 aluminum allows it to be made into different products such as chemical equipment, heat sinks, dials, railroad tank cars, and nameplates in the manufacturing industry.
3003 Aluminum
3003 aluminum is the most commonly used form of aluminum. This metal is made of 98.6% aluminum mixed with 1.2% manganese and 0.12% copper to increase its strength. It is easily welded but does not have the corrosion resistance of 1100. It is an economical alternative as 3003 aluminum coil is less expensive than other aluminum alloys. Since it is a general-purpose alloy, it can be used in cookware and pot covers but cannot withstand the high temperatures in an oven or grill.
6061 Aluminum
6061 aluminum is often referred to as "workhorse aluminum" and has excellent corrosion resistance. Its high heat welding properties along with its strength make it useful for products that are subject to high levels of wear and tear. It has excellent formability and can be used for bending, deep drawing, and stamping.
Aluminum Coil vs Steel Coil
Aluminum coil is a flat sheet of aluminum rolled into a coil, while steel coil is a flat sheet of steel rolled into a coil. Hot rolled and cold rolled steel coils are the two main types of steel coils available in the market. Like aluminum coil, steel coil's uses include making automotive parts and electronic components. Both metals are known for their ductility and affordability.
Aluminized Steel Coil
Aluminized steel coil is also known as aluminized steel coil. Some people mistakenly call it aluminum steel coil. It is nothing but steel coil coated with aluminum. Aluminized steel coil does not corrode due to the protective layer of aluminum. Here are some features of aluminized steel coil:
The strength of steel coupled with the corrosion resistance of aluminum
High temperature resistance
Low thermal expansion
Formable, can be coiled, folded, bent and wrinkled
