ISO 4489 is an international standard on hard metals that discusses the best procedures and specifications required for sampling and testing hard metals. ISO 4489 specifies procedures for sampling and testing hard metals for the determination of their physical and mechanical characteristics.  

Who is ISO 4489- Hardmetals for?  

ISO 4489 on hard metals is relevant to: 

  • Manufacturer of hard metals 
  • Laboratories and Research centers  

Why should you use ISO 4489- Hardmetals? 

Hardmetal is the term used to signify a group of sintered, hard, wear-resisting materials based on the carbides of one or more of the elements bonded with a metal of lower melting point. 

ISO 4489 navigates you through the sampling, preparation of test pieces, testing of hard metals. 

As a user of ISO 4489, you can be ensured of the physical and mechanical characteristics of hard metals and can perform sampling and testing of hard metals. With obedience and compliance to ISO 4489, you can efficiently manufacture high-quality hard metals. With ISO 4489, you can be ensured that the hard metals consistently meet and exceed quality.
