粉末冶金产品应用广泛，用于汽车、电气、商业机械、农业机械、缝纫机等行业。首先，介绍粉末冶金市场，特别是日本近期铁粉、铜粉、低合金钢粉和不锈钢粉的出货量以及各种粉末冶金产品的产量。其次，概述了粉末冶金零件的发展历程、新型原料粉末（如高压缩性铁粉、良好成型性铁粉、无偏析铁粉、高强度低合金钢粉、快速凝固铝合金粉和精细合金粉末）以及近期开发的粉末冶金零件制造技术。尽管日本粉末冶金行业在90年代初受到经济衰退的影响，但未来前景非常乐观，预计粉末冶金行业将重新增长，因为粉末冶金零件的应用涵盖众多行业，并且目前正在开发各种新型原料粉末、粉末冶金材料和粉末冶金制造技术。
Powder metallurgy products cover a wide range of applications and are used in the automotive, electrical, business machine, agricultural machine, sewing machine and other industries.First, the powder metallurgy market, especially recent shipments of iron powder, copper powder, low alloy steel powder, and stainless steel powder, and production amounts of various powder metallurgy products in Japan, are introduced.Second, the history of development in FM parts, new types of raw powder, e.g. high compressibility iron powder, good campactibility iron powder, segregation-free iron powder, high strength low alloy steel powder, rapidly solidified aluminum alloy powder, and fine alloy powder, and recently developed FM parts manufacturing techniques, are outlined.Although the Japanese powder metallurgy industry felt the effects of economical recession in the early 90s, the outlook for the future is very positive, and the FM industry is expected to show renewed growth, because the applications of FM parts range over many industries, and various types of new raw powders, FM materials and FM manufacturig techniques are now being developed.
