Cast Tungsten Carbide
PPM Ltd. production facility offers a wide range of cermet (ceramic-metal composite) powders custom produced to each individual customer's distribution specifications.
The generic term cermet is used to describe a wide range of composites consisting of ceramic particles or grains dispersed in a metal matrix. In situations where neither ceramics nor metals alone would be ideal, cermets are used. For example, metals are not thermally resistant at higher temperatures and are susceptible to chemical attack, while ceramics excel in this area. However, ceramics fall short in toughness which can be improved by the addition of a metallic binder. Therefore, cermets achieve a wider array of advantageous properties particularly in applications requiring high hardness, strength, toughness, thermal resistance, and chemical resistance.
Typical fabrication methods include powder metallurgy (P/M), infiltration, or thermal spray. Commonly used metallic binders include nickel, cobalt, molybdenum, and iron.
We have extensive experience and are familiar with the requirements of domestic and international powder metallurgical powder customers. If you have any questions, please do not hesitate to contact our capable and experienced engineering staff. Samples for qualification are available upon request.
