Abstract
Molded articles, particularly cams for camshafts of internal combustion engines, are subjected to high wear conditions. In order to make them resistant to wear, they are produced from a sintered alloy, which has been fabricated by powder metallurgical means. The alloy has a hardened matrix with interstitial copper and consists of 0.5 to 16% by weight of molybdenum, 1 to 20% by weight of copper, 0.1 to 1.5% by weight of carbon and, optionally, of admixtures of chromium, manganese, silicon and nickel totalling, at most, 5% by weight, the remainder being iron.
