Mould tooling alloy metal powder
The standard range of Osprey® metal powder includes a wide variety of mould tooling alloys to be used in, for example, additive manufacturing and metal injection moulding (MIM).
Mould tooling alloys benefits
Our mould tooling alloys are used in a range of applications where high strength, hardness and wear resistance are key attributes.
The table shows our standard range of mould tooling alloys. Other mould tooling alloys are also available. Contact us to discuss our full range of metal powder alloys.

General information about mould tooling alloys
Osprey® mould tooling alloy powders, include maraging steel, stainless steel and hot work tool steel powders. Manufactured by inert gas atomization, using optimised process parameters and equipment designed for additive manufacturing, with the option to melt under vacuum for enhanced melt cleanness and low non-metallic inclusion counts. Alloy powders designed specifically for additive manufacturing processes, including Laser & Electron – Beam Powder Bed Fusion, Binder Jet, Direct Energy Deposition and Laser Cladding. Suitable of applications including conformal cooled plastic mould tools and tire mould segments and sipes.
- Maraging steels have low carbon contents, that can be heat treated, to high and ultra-high hardness, without distortion
- Mold tooling stainless steel combines high mechanical strength, hardness and corrosion resistance
- Hot work tool steel suitable for operation at high temperature in die casting applications
