We specialize in producing Bimetal al-cu washers,One side of the bimetallic washer is copper and the other side is aluminum. The proportion of copper to aluminum is 80% aluminum, 20% copper, the proportion and size of aluminum and copper can be customized according to your requirements.
We are using innovative patented technology: solid- liquid processing technology, make permanent Al Cu solid combination, higher conductivity, lower than the cost of copper，High composite strength, It can do deep processing, such as bending, drilling, stamping, and so on，and the chemical composition is stable. The raw materials are all high quality products, The copper material is made of T2, and the aluminum is 1070 pure aluminum,the high-quality raw materials to ensure product quality .
Bimetal al-cu washers is mainly used for copper and aluminum transitional connection, To avoid copper and aluminum directly connected between the electrochemical corrosion of copper and aluminum, the resistance increases, resulting in local heating circuit caused a variety of electrical accidents. At present, it is mainly used in reactor, lithium battery, electrical components and so on.
