For thin-walled components (30 mm max) that are subject to a combination of impact and abrasion

This alloy is used in the manufacture of highly abrasion-resistant castings that are also subject to moderate impact.  Its wear resistance can be reduced through heat treatment. This is an advantage for close-tolerance parts in particular, as the part can then be precision machined. The process can be reversed. Once machining has been completed, the component’s wear resistance can be restored to its previous level.

VAUTID W7 is particularly suitable for thin-walled components, with wall thicknesses of up to 30 mm. In the VAUTID W72 and VAUTID W73 variants, the composition is modified to permit higher wall thicknesses.

Recommended applications:

  • Cast components that are exposed to temperatures up to 400°C.
  • Cast components that require machining.
  • Thin-walled components (< 30 mm) that are subject to abrasion and impact, e.g. feeder screw spirals, or impact heads.

Mechanical properties
VAUTID use white cast iron materials produced to DIN EN 12513 grades GJN-HV520 – 5.5602 and GJN-HV600(XCr18) – 5.5609 for components exposed to abrasion or to a combination of abrasion and impact. Materials developed in-house by VAUTID are used in impact mills, crushers and conveyor units, commonly installed in recycling plants, asphalt works or power generation plants. Typical components include lining elements, mixer tools, pump parts, hammers and beater bars. VAUTID materials VAUTID W7, VAUTID W72 and VAUTID W72H can all be machined.
