The advantages of solid carbide cutters
Hard metals are characterized by a number of advantages that make them very suitable for the manufacture of tools. Let's take a closer look at the most important ones:
Wear resistance / toughness
E-modulus
Hardness
Compressive strength
Density
Temperature resistance
Rust resistance
Conductivity
Wear resistance / toughness
- Very resistant to abrasive processes
- Comparable to hardened steel in terms of toughness
E-modulus
- significantly higher modulus of elasticity than conventional steels
- between 400 and 650
- significantly stiffer structures can be realized with the same moment of inertia
Hardness
- significantly higher than conventional steels
- soft grades with up to 750HV30
- hard grades with up to 2000HV30
Compressive strength
- very high under uniaxial load
- compressive strength increases with decreasing binder content and grain size
- up to 8,000 MPa
Density
- about twice as high as conventional steel
- between 12.75 - 15.20 g/cm³
Temperature resistance
- up to 1,100 °C
- significantly higher than conventional cutting materials such as high-speed steels
Rust resistance
- cobalt-bonded carbides can also rust, but only on the surface
- internal structure not susceptible, unlike steel
Conductivity
- Carbides with high tungsten carbide content good conductors
- Resistance of around 20 µΩ/cm
However, carbide also has a few disadvantages and associated limitations of use.
Accordingly, it is important to use tungsten carbides exclusively in the appropriate areas of application. We have summarized what is important in the following.
- basically to be classified as a brittle material, no plastic deformation occurs before fracture
- higher weight than comparable steel components
- cobalt as binder less resistant to corrosion than nickel
Accordingly, it is important to use tungsten carbides exclusively in the appropriate areas of application. We have summarized what is important in the following.
The areas of application of solid hard metals
Solid carbide precision tools
With the above-mentioned properties, hard metals are particularly suitable for use as cutting materials and for forming.
The following advantages should be emphasized in the various areas:

Solid carbides as cutting materials
Compared to conventional cutting materials such as high-speed steels, carbides have lower thermal shock resistance and book toughness, but they are significantly harder and more temperature resistant.
Thanks to the associated higher abrasive wear resistance, significantly higher cutting speeds of up to 350 m/min are possible. Typical applications of carbide tools are therefore machining activities such as turning, drilling and milling.
Other areas of application are:

Other areas of application are:
- Knives in cigarette cutting machines
- Tools in rock mills and mines
- Ripping of hardwoods from the tropics
Solid hard metals during forming
A second important area of application for hard metals is forming. Here they are used, for example, to manufacture dies and punches. Here, their significantly higher wear resistance compared to conventional punches comes into play.
Typical areas of application are:
Typical areas of application are:
- Impact extrusion
- Wire drawing
- Extrusion
- Nozzles for textile spinning
