Application

BrazeTec 4003 is a low melting silver based brazing alloy with excellent flow characteristics. 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 or induction brazing procedures..

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