When referring to carbide, ‘corrosion’ means the detachment of the binder caused by corrosive<br />
materials. This can cause early breakage (notching!) or notably increased wear. In this context<br />
carbides containing Co/Ni or Ni or a chromium-doped binder represent an advantage.<br />
The ferromagnetic properties of cobalt and nickel make it possible to magnetise carbides which have<br />
a suitable binder. Upon request some of the nickel-bound carbide grades can also be delivered as non<br />
magnetic grades.<br />
