What is difference of 5052 aluminum and 5005 aluminum sheet?

5052 aluminum sheet can be hardened using cold working. Heat treatment cannot be used to make it hardenable. Compared to 5005 alloys, this grade of aluminum has better resistance in marine environments. It also has excellent corrosion resistance when used in slightly alkaline conditions. A protective surface film is over the 5052 aluminum sheet , which gives the metal its corrosion resistance. When damage happens, the rapid reaction between aluminum and oxygen repairs it. When the film can’t be repaired, corrosion can quickly occur to the base metal. To help prevent this from happening, the metal can be anodized, which will make the protective surface film thicker.

Color Coated Aluminum Coil

图片
Color Coated Aluminum Coil Materials of Color Coated Aluminum Coil This color coated aluminum coil uses aluminum-manganese-magnesium alloy which is a kind of aluminum material mixed with manganese and magnesium. The alloy material provides higher tensile strength and stretching strength and better oxidation and corrosion resisting properties than common aluminum. Technical Specifications of Color Coated Aluminum Coil Aluminum coil width: 200mm-1,590mm Aluminum material thickness: 0.08mm -1.2mm (±0.02mm) Outer diameter of aluminum coil: ≤1,200mm Aluminum coil weight: ≤3,000kg /coil The color coated aluminum coil can be cut into sheets in any size. https://www.alufoil.cn/coated-aluminum-coil/index_2.html Email: Sally@hwalu.com Whatsapp:+8613140068326

Aluminium foil coated paper

图片
Aluminium foil coated paper The aluminum foil paper refers to a paper made by bonding aluminum foil backing paper and aluminum foil. Soft and easy to deform, like paper, and does not rebound after deformation. It can be qualitative and guaranteed to be light-shielded, not to fall, opaque, non-polluting, and cheap. It is used for moisture-proof and decorative packaging of high-grade cigarettes and candy. https://www.alufoil.cn/aluminium-foil-coated-paper.html Email: Sally@hwalu.com Whatsapp:+8613140068326
