摘要:
A high temperature abrasion resistant copper alloy suitable for the material of engine parts such as valve seats and valve guides. The copper alloy comprising aluminum in an amount ranging from 1.0 to 15.0% by weight; at least one element selected from the group consisting of vanadium, niobium and tantalum in the group Va of the periodic table of elements, in an amount ranging from 0.1 to 5.0% by weight; and balance containing copper and impurities. The copper alloy has a structure in which at least one of intermetallic compounds is dispersed. each intermetallic compound contains at least one metal selected from the group consisting of aluminum and copper and at least one element selected from the group consisting of elements of the group Va of the periodic table. This copper alloy exhibits also high oxidation resistance and corrosion resistance at high temperatures.
