New Materials

Abstract

Brief Particulars of Recently Introduced Materials likely to have Aircraft, Missile or Space Vehicle Applications. Wall Colmonoy (Canada) Ltd. have announced the introduction of four new filler metals in their Nicrobraz series of nickel‐base brazing alloys. The new grades result from continued research to find better ways of meeting the requirements of brazing high temperature metals and special alloys. Nicrobraz 135 meets AMS. 4779 specification, has similar applications to Nicrobraz 160 and is best used where greater joint ductility or machinability is required. Nicrobraz 200 has very high creep and stress rupture strength and is recommended for hot sections of jet and gas turbine engines, and similar components where hardenable base metals are used. Nicrobraz 220 and 230 are both ductile, low penetration filler metals and can be used for cryogenic temperatures to 650 and 820 deg. C. respectively. Recommended uses for the these grades include rocket engine thrust chambers, complex and high temperature heat exchangers.
