Properties of iron-copper master alloy powder

The advantages of low-alloy sintered materials produced from iron—copper master alloy are confirmed. Physical and technological properties of the master alloy powders are determined. Experiments show that mixtures of iron, graphite, and iron—copper powders compact well to produce high-quality articles. Sintered materials have strength values (σf ∼ 345 MPa, HB ∼ 1430 MPa) comparable with those of similar materials produced using electrolytic copper.
