Hartmetall Stäbe-HM-Negele Hartmetalltechnik-Lagerprogram-lagernd


Hard as diamond. First introduced by Krupp in 1926 under the brand name “Widia”, the name of this material says it all.

Our carbides are available in any form – as blanks or as ready to use carbide components.

Having a hardness of up to 2000 HV, this material will stand up to even the toughest requirements. Our extensive experience in a wide range of industrial sectors has resulted in carbide grades with the precisely correct material composition for various applications.

Our carbide products are used as guide and drill bushings, rings and round rods, nozzles and valve components, parts for metrology and inspection equipment, molds for ceramic and porcelain manufacturing, cutting inserts and molds iaw. DIN standards, factory standards, to customer drawings, drawing and deep drawing tools, molds, inserts for powder and ceramic press tools, and for screw and nut manufacturing.

The extraordinary versatility of a carbide will secure its outstanding role as a material for wear and machining applications, in corrosion protection, mold engineering, and for stone and mining operations.

Multi-range carbide grades

We can supply all carbide grades, precisely matched to your specific needs, starting with our proven standard grades, continuing with universal multi-range grades, and ending with our specialty grades. The different properties of the individual grades are achieved with various mixture ratios of the components, and by selecting and combining the tungsten carbide grain shape and grain size, along with precisely matched process controls.

NHT has specific grades in outstanding quality for any requirement.

NHT fine-grained grades

In response to permanently increasing requirements for our carbides, we created innovative solutions in particular based on our highly-densified fine-grained grades GM05F, GM10F, GM15F, GM25F.

The fine-grained grades give you the following benefits compared to standard grades:

  • Very high ductility behavior based on high flexural strength – up to 3900 N/mm²
  • Maximum wear resistance due to high hardness – up to HV 2000
  • High edge stability due to a very fine, dense, and homogenous grain structure; as a result, these materials are particularly suited for punching and cutting tools.
