Description

Oerlikon Metco’s CoCr[NiWSi]C products are inert gas atomized powders that are chemically homogeneous, exhibit minimal satellites and are freely flowing. They are designed and provide excellent results for a variety of applications such as laser cladding, thermal spray and PTA. These materials form coatings that are appropriate for wear and corrosion resistance in relatively high-temperature service conditions.


Metco 1220 series materials have chemical compositions similar to that of Stellite 6. Metco 1220 series materials are designed for laser cladding.

Deposits have good resistance to seizing, galling and cavitation over a wide temperature range, and combat adhesive, abrasive or erosive wear combined with corrosion at relatively high temperatures. They provide good thermal oxidation resistance at temperatures up to 1000°C (1800 °F). Deposits resist oxidizing acids, but perform poorly in strong reducing acids such as hydrochloric with the degree of resistance dependant on the acidic concentration and temperature. Self-mating surfaces exhibit a very low coefficient of friction (≈ 0.12). Choose Metco 1220A for laser cladding deposits of standard thickness.
