Product Uses and Applications

High temperature copper based brazing alloys can provide an economic alternative to silver brazing filler materials. The alloys contain nickel and / or manganese and show improved wetting on tungsten carbide. When brazing certain grades of steel, using these brazing alloys may enable a simultaneous heat treatment step to take place. If brazing in air it is necessary to use a Meta-Braze brazing flux that is suitable for use at high temperatures.

Meta-Braze Cu 087

Meta-Braze Cu 087 is a special copper based brazing alloy. It contains manganese and nickel which have been shown to improve wetting of the filler metal on tungsten carbide. This alloy is has been used to manufacture professional grade masonry drills and associated tools for construction work. It can be brazed in a reducing atmosphere provided the dew point is better than -40°C.
