Sandvik’s world leading Osprey™ metal powders, now also includes nickel-based alloys for additive manufacturing

Nickel-based superalloys for additive manufacturing

Sandvik is now adding nickel-based superalloys to its word-leading Osprey™ metal powder program, produced in our state-of the art atomising plant with melting under vacuum. The powder can be used for near-net-shape technologies like Additive Manufacturing (AM) or Hot Isostatic Pressing (HIP).

Based on Sandvik’s 150-year material knowledge and in-house powder manufacturing and R&D capabilities, we are experts at matching material to any application. We offer the widest range of alloys around and can even customize materials.

In addition, Sandvik also has all relevant Additive Manufacturing processes for metals inhouse, which means that we can adapt the powder to any printing process.

Nickel-based superalloys

Nickel-based alloys are typically used in applications like jet turbines, gas turbines, oil and gas, pressure vessels or chemical processing components. We can offer Alloy 625, Alloy 718 and H-X. Other alloys are also available on request.

Due to Sandvik’s vacuum induction melting process, our powders offers significantly lower oxygen and nitrogen levels than conventional metallurgy, typically below  250 ppm. Lower levels of O and N can be offered but needs to be discussed related to the type of Ni-base alloy.
