Application

BrazeTec CoMet 4576 U is a flux coated low melting silver based brazing alloy with excellent flow characteristics. The flux residues are corrosive and have to be removed. It can be used for brazing any steels, copper and copper basedalloys as well as for nickel and nickel based alloys.

It can be used for brazing with flame.

Typical applications are found e.g. in the electric and automotive industy.
