White Cast Iron

White Cast Iron

White, Ni-Hard, Ni-Resist cast iron

This type of cast iron is obtained by a low casting temperature, rapid cooling, a high content of pearlitizing elements (ex: manganese, copper, etc.) or a low content of graphitizing elements (ex: silicon)1.

Possessing good flowability and bright white appearance, white cast iron is mainly used for the physical appearance of parts, wear parts in mining, asphalt machinery, etc. The presence of carbide makes it very resistant to wear and abrasion, but also makes it more difficult to machine.

Norms:

ASTM A532

The main qualities of white castings are :

  • Excellent resistance to cold and hot wear and abrasion
  • A beautiful appearance
  • Excellent flowability
  • Very high Brinell hardness: (350 to 750)
  • Parts often used in mining and asphalt for wear parts
