Aluminium pad 4 series

annealed

Aluminum coil is the rolled product that has been calendered by a finishing mill but has not been processed by a leveling flying shear. It is the raw material of aluminum strip and aluminum sheet. The slitting equipment can cut aluminum coil into aluminum strip, and the flattening equipment can make aluminum coil into aluminum sheet. Aluminum coils can be divided into different types according to different alloys, applications and surface treatments. Features: 4004 is a hypoeutectic aluminum alloy. It has the characteristics of low melting point, good fluidity, easy feeding, etc. It is usually used as a substitute for composite plates, and also widely used as aluminum brazing materials. Features: 4017 aluminum strip is annealed by continuous heat treatment line, with accurate size and high flatness. Features: 4045 aluminum coil is suitable for brazing aluminum alloy 3004, 5005, 6063, 6951, and can get excellent welding joints Aluminum coil classification according to the surface treatment process Color coated aluminum coil Color coated aluminum coil is to paint the surface of aluminum substrate. Common color coated aluminum coils include fluorocarbon (PVDF) color coated aluminum coils and polyester (PE) color coated aluminum coils. Chalco Aluminum can also product black color coated aluminum coils, white color coated aluminum coils, wood grain aluminum coils, stone grain color coated aluminum coils, etc. The polyester (PE) coated aluminum coil is formed by baking and coating polyester (PE) materials on the surface of aluminum coil for many times. PE coating has good adhesion to materials, so it is widely used, and the basic corrosion resistance can reach 7-8 years.
