Copper-steel composite material is a bimetallic composite material with steel as the base material and continuous coating of copper with a certain thickness on one or both sides of the steel by rolling diffusion process. This new material perfectly combines the advantages of copper and steel, making the new material have the following characteristics:
Good electrical conductivity/ good corrosion resistance/ high strength/ good formability/ good weldability/ high cost performance.
Brass clad steel warheads is the material used for warheads, H90/F11/H90
