Ni-based superalloys for additive manufacturing

Due to our vacuum induction melting process, our powders offer 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.
