MetcoClad 625F Nickel-Based Superalloy Powders for Laser Cladding and Laser-Additive Manufacturing

Alternative and trade names
similar to Inconel 625 (Inconel is a registered trademark of Huntington Alloys Corp.), MetcoClad 625


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.

Handling recommendations

Store in the original container in a dry location; Tumble contents prior to use to prevent segregation; Open containers should be stored in a drying oven to prevent moisture pickup.

Order number



Laser clad surfaces exhibit high corrosion resistance that are stable against intercrystalline, pitting and crevice corrosion in a wide range of media. Maintains physical properties at both low and high temperatures and resists oxidation at elevated temperatures up to 1000 °C (1830 °F). When heated, forms a stable passive oxide layer that protects the surface from further attack. Exhibits high temperature strength as a result of precipitation strengthening. Choose MetcoClad 625F for thin deposits as low as 0.2 mm (0.008 in) and high speed laser cladding, for which special nozzle designs are generally required.
