Base Chemicals Features
Features
  • High Hardenability - the precise levels of manganese, molybdenum and nickel enhance heattreated properties for improved hardness and strength. This can be sinter-hardened when admixed with copper.
  • High compressibility - outstanding compressibility extends the benefits of low alloy compositions to high-density applications over 6.8 g/cm3. Higher strength, higher density PM parts with reduced tool stress become possible.
  • Dimensional change - This can be used with existing tooling designed for conventional AISI 4600 prealloyed powders. Retooling is not required.
