Overview
Cemented carbide offers high compressive strength, hardness and wear resistance. DSP supplies tungsten carbide balls with cobalt or nickel binders for valves, flow meters, ball screws, linear bearings, gauging and ballizing. Nickel-binder grades resist corrosion down to roughly pH 2–3 versus cobalt binder (~pH 7).
- Cobalt & nickel binder options
- High hardness & wear resistance
- Corrosion-resistant nickel grades
- Valves, bearings, gauging & ball pens
