Under the constraint of more and more strict emission policy and NEVs battery life bottleneck, replacing steel with aluminium rolled products to promote automotive light weight is the optimal decision combining weight loss and economy. Kobelco recommends you the aluminum alloy plate comparable to the characteristics of a cold-roll steel sheet.
■High strength comparable to steel and ultra high formability with 30～34％ elongation rate.
■Hardness after stamping pressing won’t decrease with baking.
■Strong corrosion resistance and excellent seaming property.
■Low AS strength, excellent formability and shaping ability of early material
■Very high strength even with low baking temperature
■Strong corrosion resistance and excellent seaming property
Automotive aluminium alloy’s difficulties lie in high machinability, low error of batch production, super high stability and high surface cleanliness. With Japanese rigorous craftsmanship, Kobelco Automotive Aluminum Rolled Products (China) Co.,Ltd always maintain industry leading in automotive material field.
Different types of alloy have different strength, corrosion resistance and machinability, so choose alloy according to different requirements.
Alloy for automobile panel is divided into two categories, Series 5000 and 6000.
Kobelco can produce custom alloy to meet various needs according to specific preferences for automotive [appearance design] and [body strength].
