bimetallic strip aluminum and copper

Bimetallic strip aluminum and copper combines the high electrical and thermal conductivity of copper, as well as the light weight, easy welding, and low cost of aluminum. It has good mechanical properties, electrical conductivity, thermal conductivity and corrosion resistance. The section bonding strength is the core mechanical performance index of Bimetallic strip aluminum and copper. For example, the copper-aluminum composite interface bonding strength used in the power industry should be greater than the DL/T247 standard value of 35MPa. If it is less than the standard value, the stress generated by thermal expansion and contraction will destroy the copper-aluminum interface bond, causing electrochemical corrosion and operation. There are serious hidden troubles of faults, breakdown short-circuit occurs, and even electrical fires.



The mechanical properties of Bimetallic strip aluminum and copper include interface bonding strength, tensile strength, bending strength and microhardness.

The skin effect of Bimetallic strip aluminum and copper makes it have a higher conductivity than a single aluminum after the current is applied. Especially when the frequency of the current exceeds a certain value, the current basically passes through the surface. Bimetallic strip aluminum and The conductivity of copper is similar to that of pure copper.

Bimetallic strip aluminum and copper are widely used in power systems, such as lithium-ion batteries, radiators, etc., which require strong corrosion resistance. Due to the different service environments of copper/aluminum bimetallic composite materials, there are also differences in corrosive media, and the corresponding research focuses are different. Among them, the corrosive medium includes acid, alkali, salt, water vapor and solid particles.

Bimetallic strip aluminum and copper are widely used in electric power, air-conditioning, new energy vehicles, kitchen utensils and other fields, and its comprehensive performance advantages are obvious.
