Copper aluminium bi-metal bimetallic washers are mainly used for copper-aluminum transition connection to avoid electrochemical corrosion between copper and aluminum caused by direct connection of copper and aluminum, resulting in increased resistance, resulting in local heating circuit caused by various electrical accidents.

 
Henan Chalco adopted a number of patented technologies to carry out industrial continuous composite production under high temperature and oxygen-free conditions, which fundamentally solved the problem of oxidation and eutectic between the two metals. It not only effectively guaranteed the bonding strength and bonding rate between the two metals, but also guaranteed the product quality and large-scale production. The copper aluminium bi-metal bimetallic washer
 produced by Henan Chalco effectively solves the problem of transition connection between copper and aluminum, avoids electrochemical corrosion, and avoids the circuit breaking accident caused by the increase of contact resistance between copper and aluminum.

 
Suitable for various types of reactors, transformers, power transmission and distribution industries, used for the transition between copper and aluminum connections.
 
Product features: uniform thickness of copper and aluminum, stable quality, high composite strength, high conductivity, low cost.
