Description

WL NI-770 Ams4777 AMDRY770 Nickel Base Powder Furnace Brazing Gas Atomization Mild Filler Metal Mild Steels

Product Description

The WL-Ni 770 series of braze filler metals are spherical, inert gas atomized, nickel braze alloys containing silicon and chrome.

This alloy offers excellent strength and oxidation resistance at temperatures up to 982 °C (1800 °F). The lower viscosity of the molten alloy allows successful brazing of gaps up to 0.12 mm (0.005 in).

WL Ni-770 filler metals are used in furnace brazing of aircraft and aerospace components, commercial products such as food processing equipment and heat exchangers. Components with joints that are exposed to high stresses in service benefit from brazing with WL Ni-770 filler metals. The lower chromium content makes these filler metals good choices for nuclear applications.
