Bimetallic washer

Copper aluminium 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.

Bimetallic washer

Stable quality and high conductivity

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 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.

Product features: uniform thickness of copper and aluminum, stable quality, high composite strength, high conductivity, low cost.

These are plain washers but with two diferent metals on wither side. We can also manufacture the same according to the composition of copper and aluminium that you require.

These can be manufactured in mm & Inches as per your requirements, specifications & drawing or as per the sampel provided by you.

Applications:

Bimetal plates and washers are used for connections between copper conductors and aluminium one's, in order to avoid corrosion that makes connection ineffective and unreliable.

Suitable for various types of reactors, transformers, power transmission and distribution industries, used for the transition between copper and aluminum connections.
