6. Tinplate Application:
Tinplate is widely used for making all types of container including:
l Food Cans
l Beverage Cans
l Aerosol Cans
l General Line Cans
l Crown Cork
l Twist-off Caps
l Decorative Cans
l Components
MARK: D-type is Aluminum-Killed Steel, whole aluminum content will be≦0.020%, specialized in ultra-deep timeliness resistance.
L-type with lower content of Non-metallic inclusions and Residual elements, widely used in high corrosion resistance products.
MR-type with lower content of Non-metallic inclusions (similar with L-type), but the limitation of Residual elements doesn’t as strict as L-type. Widely used as base material for food packaging and other Tinplate purpose.
