Copper manganese cobalt alloys contain copper, manganese and cobalt. It belongs to high temperature copper based brazing alloys, which can provide an economic alternative to silver brazing filler materials. Copper base brazing materials has one thing in common: they dissolve better than the corresponding pure metal or metals.

In most cases, hard alloy as cutting tools,hard wearing tools and shockproof tools, need to connect to based metals, and brazing is the most important method for connecting. The difference of swell factor between hard alloy and steel is great. So great stresses will be produced in the process of colling after brazing, and cracks tend to be produced, which is the most important problem for brazing. Selecting suitable brazing filler metal CuMnCo and brazing technology, adding interlayer and so on, could reduce brazing stress, and realize the perfect brazing between hard alloy and steel 5Cr.MnMo.
