Customized Copper to Aluninum Bus Bars for Electric Power

Copper to aluminum is a new type of conductor material which combines the high quality, stable and conductive properties of copper with aluminum's low cost energy and combines low contact resistance. Widely used in automation, metallurgy, high and low voltage electrical equipment, construction industry and metallurgical industry.


RHI manufacture and supply wide range of fabricated aluminum busbars. 

Cu-Al bimetallic material is a new technical material, based on different industry needs,formed by advanced machining processing technique: Solid-Liquid machining processing technique to bond copper and aluminum in oxygen-free environment permanently and firmly, which decided the alloy and base material characteristic are better preserved. It is suitable for continuous automatically manufacture and does not need other manufacture process, such as welding or soldering after its formation. 

CCA busbar is replacing copper busbar for electrode of electrical equipment, industry and building electricity control cabinate, subway and high speed train electricity transmission, it voids the cooked surface, arcing, overheat, reduces power consumption,has significant economic and practical prospects.

Cu-Al bimetallic Bus Bar Advantages:

  • Produced by innovative patent technology——Solid-Liquid machining processing technique to bond copper and aluminum permanently and firmly;

  • With higher electric conductivity: Can reach more than 98% of the same volume conductivity of pure copper;

  • Lighter than pure copper: About 1/3 weight of the same volume of pure copper;
  • Lower cost than pure copper;
  • 90 degree bend do not wrinkle, stamping no cracking, easy processing;
  • Meet all thickness between 0.20mm to 15mm in ratio of 20Cu:80Al by thickness for Cu-Al Bimetal;
  • Unlimited for length and area.
