传统上，烧结材料被认为在拉伸强度和冲击能等机械性能上不如锻造材料可靠，因为它有相应的孔隙。因此，烧结材料被认为不适合应用于重要的安全相关部件。目前，利用具有优异压缩性的部分合金化钢粉，通过高密度压实、高温烧结和精确控制热处理等先进技术，可以生产抗拉强度超过110kgf/mm2的烧结材料。1979年，东京烧结金属公司作为世界上第一家生产汽车动力转向油泵零件的生产商，率先生产汽车动力转向油泵零件。在每一个行业中，小型化和轻量化都是时代的潮流，这类机械构件的应用条件也越来越苛刻。我们成功地开发出了高韧性、高耐磨性和高抗拉强度的材料。这种材料目前已应用于汽车起动件的生产。
Conventionally, sintered materials have been considered less reliable than wrought materials in mechanical properties such as tensile strength and impact energy, because of its consequential pores. Thus, sintered materials have been thought unsuitable for applications in important safety-related parts.Now, production of improved sintered materials with tensile strength exceeding 110kgf/mm2 has been made possible by developed techniques of high density compaction, high temperature sintering, and precisely controlled heat treatment, using partially alloyed steel powders with excellent compressibility. In 1979, as the first producer in the world, Tokyo Sintered Metals Corp. pioneered production of automotive power steering oil pump parts.In every industry, compactness and light-weight are the current of the times, and applied conditions for such machine component constructural parts are getting severer. We have succeeded in developing material which has high toughness and wear-resistivity in addition to high tensile strength. This material is now applied in production of starter parts for automobile.
