ABSTRACT:
A sintered material resistant to heat and mechanical strain, particularly to impact and friction, for the production of molded articles, made of a matrix metal powder having approximately 70 to 100% by weight of a copper component and approximately 0 to 30% by weight of an alloy component of cobalt, chromium, iron, manganese, nickel, tungsten and/or carbon. In another embodiment, the sintered material may also include an additional high-alloy metal powder admixed as a hard phase to the matrix metal powder. The additional high-alloy metal powder is present in the amount of a maximum 30% by weight, with respect to the sum of the matrix metal powder and high-alloy metal powder. The sintered material is especially suitable for heat- and wear-resistant molded articles for use in high gas environments, for example, in internal combustion engines. For example, guides, bearings, and valve elements may be made of this material and especially valve seat rings.
