In the metallurgical industry, copper-steel clad metal is used for electroplating, electrolysis electrode, processing electrode for discharge, grounding rod, current conducting arm body, electrode clamp, and an electrode clamping-release device and so on. Copper-steel or aluminum-steel clad metal can be used for bimetal bearing, bearing bush, and liner tube, wear-resistant plate, self-lubricating slide plate, etc.. Copper-steel clad plate can make electrometallurgical furnace and bi-layer water cooling shell & bi-layer crystallizer of melting furnace.
