DrilTec® STC-100 Series

Composite Alloy Rod

Our Composite Alloy Rod is made of crushed Tungsten Carbide (WC), embedded in a Nickel Bronze matrix with either sharp-edged cutting grade carbides for milling and cutting operations, or our wear grade, with slightly rounded edges, for applications such as stabilizers and wear pads.

Process description

The composite rods are normally applied using a large oxy-acetylene torch, in conjunction with a range of our brazing fluxes or with our gas flux system, where the flux is introduced to the gas before the flame, thus making it easier for the operator to place the cutting carbides in the correct position. To prevent leaching of the Nickel Bronze alloy, a thin tinning layer of our powder from the STC 400 series is applied using our SuperJet Eutalloy S. A typical example of powder would be STC-326LT but most of our 400 series powders can be used. Pre-heats are determined by the base metal.
