Copper sheath aluminum bus bar produced by the parallel continuous casting method.

Insert the dissolved copper liquid into the vacuum compound furnace to form
the copper pipe and insert the dissolved aluminum liquid into the copper pipe.

Surface interface fusion is formed as the aluminum and the copper are collaterally melted
which are in the inner walls of the surface of the melted copper pipe at a high temperature.

The copper and aluminum which formed the surface fusion are formed
as a new compound through a chemical reaction and the new
combination(metallurgic combination) is completed, due
to which the surface interface reaction is realized.

The two metal liquids form the stable crystallization zone after being cooled correctly the 2nd
time and the 3rd time after passing the compound molding (this zone is the closed zone filled
with the metal liquid) and any liquid can not enter it.) and when the coagulated bar(sheared
billet) is output after going through the moving processor, the copper aluminum billet is
completed.
