PTA and Weld Hardface Materials



Our portfolio of carbide hardface materials has been designed for most of the industrially used hardfacing processes. Each product is tailored for the individual weld process with tightly controlled particle size distribution and morphology.  Whether you need hardfacing products for oxy-acetylene welding, MIG, TIG, or plasma transferred arc welding, we have products that will excel in your application.

As experts in the manufacture of carbide materials, we can produce products with a very broad range of carbide grain sizes and morphologies; tailored for both cutting and wear applications. In addition, the matrix component of our products are tailored for the service environment in terms of characteristics such as hardness and corrosion resistance in a variety of media. We are also able to deliver our carbide materials to customers who wish to blend them with their own matrix.
