copper washer on aluminum

Jan 06, 2023

For the copper washer on aluminum manufactured by explosive welding process, judging from the naked eye, the bonding layer presents a sawtooth shape, that is, the two atoms of copper and aluminum are metallurgically bonded, penetrate into each other and closely bite together. If destructive stripping is carried out by instruments, it will be very laborious. The stripped copper plate will be the whole piece without fracture and slag dropping, and the composite surface of copper presents silver white, Because the bonding strength is very high, the aluminum under the bonding surface is pulled off during the tensile meeting, so it shows silver, and there are wavy stripes on the surface. It feels astringent to hang your hand with your fingers. This is the trace formed by the shock wave in the process of explosive welding. In other processes, such as cold rolling, hot rolling and cast rolling, the copper layer is easy to separate. After separation, the copper layer generally accounts for only about 10% of the total thickness of the composite material. In stripping, the copper skin is easy to tear and drop slag, and the contact composite surface is yellow, that is, the color of the copper material itself. Because the combination does not realize mutual melting, the surface is smooth and bright without any roughness

Copper washer on aluminum is a kind of conductive material with stable performance, high conductivity, easy molding and processing, and stable output performance. It is not affected by the use environment, the composite surface will not break, and can achieve excellent conductive transition without reinforcement measures. Copper washer on aluminum is mainly used for high and low voltage electrical appliances, electronic components High and low voltage power transmission and transformation accessories need to realize copper aluminum transfer. The materials are T2 pure copper and 1060 pure aluminum. It can be processed and produced according to the requirements of customers, or it can be matched arbitrarily according to the materials selected by customers. Its geometric size can meet the requirements of any size joint at present. The minimum thickness of copper washer on aluminum supplied by aluminum is 0.3mm, and the maximum thickness can be customized according to the needs of customers
