Material Capabilities

GKN Sinter Metals offers the broadest material selection in the industry to meet a wide range of needs. 

When selecting the best powder metal material for a particular application, consideration is given to requirements such as strength, ductility and wear-resistance. With our advanced alloys and processing techniques, GKN PM components often exceed industry performance standards. 

PM material types by process technology

GKN´s PM process capabilities not even match with all traditional material types, it rather excels them due to the fact that PM allows for unique material combinations that cannot be produced with the traditional iron melting furnace process.


That is why the GKN PM technology offers unique product solutions and benefits for diverse markets from Automotive, Medical, Aerospace, Industrial to Consumer product applications!

An excerpt of unique PM benefits …

  • Lightweight Materials
  • Weight Reduction featured by PM specific design
  • Reduced Assembly/Process Reduction
  • Improved Thermal Conductivity
  • Recyclability/Sustainability
  • Tight tolerances (without machining)
  • High Wear Capability
  • Net-Shape Forming
