Product Applications

DC01 is suitable for simple forming operations such as bending, embossing, beading, and basic drawing applications.
DC02 is designed for general drawing applications requiring improved formability over DC01.
DC03 is intended for deep drawing applications and complex profiles requiring good formability.
DC04 is ideal for high deformation requirements, deep drawing of complex parts, and applications demanding excellent surface quality and superior formability.
