Description

MetcoClad™ nickel-based superalloy powders are gas-atomized products specifically designed for laser cladding applications. As welded, they produce surfaces that are resistant to a wide range of corrosive media and guard against crevice corrosion and pitting, as well as other generalized and localized corrosion.


Gas atomization ensures that the powder particles are chemically homogeneous, yielding excellent results during processing. When used for laser cladding, dilution rates are low and surfaces are nearly 100% dense.
