Ni-based superalloys Osprey® Alloy 625 and Alloy 718 are produced using an vacuum induction melting process. This results in powders with 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-based alloy.
