ABSTRACT:
A method for the manufacture of tools and components for the offshore field and the mining industry, in particular, for drilling installations, using a spray formed Cu—Ni—Mn alloy of 10 to 25% Ni, 10 to 25% Mn, the remainder being copper and common impurities. Due to the favorable characteristics of the combination, the alloy is suitable as a replacement material for Be-containing copper materials.
