天津市粉末冶金厂在生产铁基、铜基粉末冶金零件的基础上,于去年进行了铝基粉末冶金新材料的研制。铝基粉末冶金材料是一种重量轻,耐腐蚀、耐磨、噪音小、承压能力大的新型材料。其生产工艺是:选料→混料→压制→成型→烧结→精整和复压。铝 Based on the production of iron-based and copper-based powder metallurgy parts, Tianjin Powder Metallurgy Plant developed the aluminum-based powder metallurgy new material last year. Aluminum-based powder metallurgy material is a light weight, corrosion-resistant, wear-resistant, low noise, pressure capacity of the new material. The production process is: choice of materials → mixing → → molding → sintering → finishing and re-pressure. aluminum
