Molded products, especially camshaft cams of heat-resistant engines, suffer from high wear. In order to be able to withstand them against wear, they are made from small alloys prepared by powder metallurgy means. The alloy has a cured matrix containing cracked copper, chromium with 0.5-16% by weight of molybdenum, 1-20% with copper, 0.1-1.5% with carbon, and optionally up to 5% by weight in total. And a mixture of manganese, silicon and nickel. |
