Manufacturing Process of aluminum coils: From Raw Material To Coil Form
HXSCO is an aluminum coil supplier that offers a one-stop shopping experience. We do all our own processing (from raw material extraction to the final coil) in-house at our factory. Our specialty is manufacturing high-quality aluminum coils with consistent standards.
Raw Material Procurement:
- Firstly, we buy high-quality ingots of aluminum or scrap aluminum that has been recycled. These materials are carefully chosen by responsible aluminium coil manufacturers to ensure uniformity and purity of raw materials.
Smelting and Casting:
- The selected aluminum is then melted in the furnace. The molten aluminum is then cast into semi-finished products such as billets or slabs.
Hot Rolling:
- We reduce the thickness of the billet or slab through hot rolling to achieve the desired specifications. This process improves the mechanical properties of aluminum and makes it more ductile.
Cold Rolling:
- After hot rolling, the sheet metal undergoes cold rolling which further reduces its thickness to meet specific coil application requirements. Cold rolling ensures a smoother surface finish as well as tighter tolerances on thickness.
Annealing:
- To optimize its properties, cold rolled coils are annealed. As such, this heat treatment process relieves stresses within and increases the material’s flexibility.
Coiling:
- After annealing, the aluminum strip is coiled into large continuous rolls known as the aluminum coil. These coils are ready for further processing or direct use in various industries.

How to choose aluminum coil?
To ensure the material meets your needs, you must choose the right aluminum coil. There are several factors to consider when choosing the right aluminum coil, and here are some simple steps.
- Determine thickness and width (which affects durability and usability).
- Evaluate alloy type. Different series of aluminum alloys have different properties. For example, the 1000 series is highly ductile; the 5000 series has high strength and corrosion resistance.
- Consider the appropriate temper grade to meet specific mechanical requirements. The temper of an aluminum coil affects its hardness and strength.
- Check the specific surface finish you need to provide additional corrosion protection and aesthetic value. For example, rolled finish, painted, or anodized.
- Determine the end use. For applications exposed to harsh conditions, you need to choose an alloy with corrosion resistance.
