Aluminum Coil

Short Description:

Aluminum coils are made of aluminum plates or strips rolled by casting and rolling mills. They are lightweight, corrosion-resistant, and have good thermal conductivity. They are widely used in construction, transportation, electrical appliance manufacturing and other fields. Aluminum coils are divided into different types, such as ordinary aluminum coils, color-coated aluminum coils, galvanized aluminum coils, etc.

Aluminum Coil Features

1000 Series: Industrial Pure Aluminium. In all series, 1000 series belongs to the series with the largest aluminium content. The purity can reach over 99.00%.

2000 Series: Aluminium-copper Alloys. 2000 series is characterized by high hardness, in which the content of copper is the highest, about 3-5%.

3000 Series: Aluminium-manganese Alloys. 3000 series aluminium sheet is mainly composed of manganese. The manganese content ranges from 1.0% to 1.5%. It is a series with better rust-proof function.

4000 Series: Al-Si Alloys. Usually, the silicon content is between 4.5 and 6.0%. It belongs to building materials, mechanical parts, forging materials, welding materials, low melting point, good corrosion resistance.

5000 Series: Al-Mg Alloys. 5000 series aluminium alloy belongs to the more commonly used alloy aluminium series, the main element is magnesium, the magnesium content is between 3-5%. The main characteristics are low density, high tensile strength and high elongation.

6000 Series: Aluminium Magnesium Silicon Alloys. The representative 6061 mainly contains magnesium and silicon, so it concentrates the advantages of 4000 series and 5000 Series. 6061 is a cold-treated aluminium forging product, which is suitable for applications requiring high corrosion resistance and oxidation resistance.
