Identification and selection about quality copper / aluminum fabricated busbar

Copper and aluminum combined with interfacial strength directly affect their processing performance and operational reliability, acopper / aluminum fabricated busbar most critical performance and stable basis, during the 90 ° bend when no blistering, no cracking. Punching, shearing does not occur when copper and aluminum layers, to be used in electrical equipment, so that stable equipment performance, ease of use.
Copper clad aluminum fabricated busbar is a double metal carrier, copper is an excellent alternative to the busbar, copper clad aluminum row copper surface while keeping the same characteristics, the more economical than the weight saving advantages of copper busbar .
Due to the different various plant processes, the production of copper clad aluminum busbar even look very similar, but their different bonding strength . Mechanical pressure to copper, aluminum crimp composite, can only be activated atoms to form atomic bonding interface, combined with the point of observation, copper and aluminum to effectively connect adhesions, but adhesions between the atomic diffusion depth and thickness of thin, combined with surface bonding strength is not high . Only under specific processing conditions, so that copper and aluminum completely fused, combine to form a uniform interface connection, and a composite layer having a uniform thickness, to achieve a higher bonding strength at the bonding interface .
The simplest identification method: direct observation copper / aluminum fabricated busbar outer copper layer was observed on the copper layer adhered aluminum thickness and uniformity, and can be used over 500 times the electron microscope and the thickness of the bonding interface is uniform copper layer.
