Carbide Brazing Alloys
Lucas-Milhaupt offers several products for brazing carbide and diamond cutting tools. These materials typically include nickel or manganese (or both) to facilitate wetting of the carbide and increase bond strength. Many of these alloys are also available in a Tri-metal form. These Trimet® alloys consist of two layers of brazing filler metal clad onto a core of copper. This eases the stresses that arise due to the differences in thermal expansion between the carbide and base metal and is particularly important when joining carbides larger than one half inch.
