Battery Negative terminal made of
Copper-Aluminum bimetals by stamping for CATL/BYD's battery to
replace traditional friction welding Copper-Aluminum negative
terminal, due to much lower cost
and and
no limit of production capacity.




Our Copper-Aluminum Bimetal Composites material is
a plating of copper on aluminum. The two metals
are combined together through
our patented technology which we
called Oxygen-free Semi-molten
rolling compound technology. This technology
solves the technical problems of oxidation and eutectic of
copper-aluminum composite.
