Abstract

The invention proposes a metal-powder blend which can be produced simply and can be used to manufacture high-strength wear-resistant cylinder parts to tight dimensional tolerances. This metal-powder blend consists of a steel powder formed by atomizing a steel melt and mixed with 0.3-0.7 % by wt. of graphite, the steel powder consisting of: max. 0.02 % by wt. C; max. 0.03 % by wt. Si; ).05-0.25 % by wt. Mn; 2.5-5.0 % by wt. Ni; 0.2-1.5 % by wt. Mo, remainder iron and the usual impurities and the blend contains in addition 0.7-1.5 % by wt. of finely divided Cu, with the provision that the weight ratio of Cu:graphite lies within the range 1.4-2.5.
