B.for hard copper clad steel
B.for hard there are four kinds of copper clad steel grades, 40 hs, high strength and conductivity 40%;40 ehs, ultra-high strength, electrical conductivity 40%;30 hs, high strength, electrical conductivity 30%;30 ehs, ultra-high strength, electrical conductivity of 30%.Applicable to electrical, electricity, electronics and communications, and other fields, it has the electrical conductivity of copper, and the strength of the steel, the load is big, the wind resistance is strong, good weldability, conductive performance is stable.
 
Note: other specifications can be customized according to customer's requirements.
