P 金属粉末 RDOUCT

Aluminum alloy powder

Refers to as the base, iron, nickel and cobalt in the high temperature of 600 ℃ above and must be long-term work stress environment of metal materials, has high temperature strength, good resistance to corrosion resistance and oxidation resistance and good plasticity and toughness; Mainly used in high performance engines, in the modern advanced aircraft engine, high temperature alloy material usage accounts for 40% ~ 60% of engine total quality, but also widely used in nuclear power, chemical, and other fields.
