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.

The Trimet Alloy Advantage

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.

Is Trimet® Carbide Brazing Right for You?

The selection of TRIMET® material for carbide applications is dependent upon base metals, service conditions, heating method, and size of the assembly. Brazing of small carbides (less than 0.5 in.2 in surface area) may not require the use of a TRIMET®, but its use on larger pieces with a surface area greater than 0.5 in.2 have proven very beneficial in preventing cracking and warpage of the carbide.
