Material Solutions for the
Cutting Tools Industry
P&I understands the importance of corrosion and oxidation resistance and joint strength in the demanding applications of the cutting tool and oil & gas manufacturing industries. Our team is well-versed in the rigorous service conditions demanded by these applications and can offer expert recommendations on the highest-performing brazing alloy for your application that provides excellent joint integrity to extend product lifetime.
Common applications for our brazing products include tungsten carbide tipped tools, where the braze alloy is used to attach the tungsten carbide tip to the steel tool body to increase rigidity and sharpness, and down-hole cutting and drilling bits, specifically in polycrystalline compact diamond (PCD) and polycrystalline diamond compact (PDC) applications.
