We Specialize in all Material Solutions

Heat Treating

Heat Treating includes all the various metalworking processes which are used to change the properties of a material to make it useful.

Brazing & Joining

Brazing is a metal-joining process where two or more materials are joined together by a third, dissimilar material to bond them together.


Aluminum is one of the most abundant elements on Earth, but it needs to be heat treated to be useful to machinists and consumers.

Secondary Operations

Secondary Operations are all those steps beyond just heat treating and brazing that add value to our customers and their parts.
