JM Bronze™ filler metals are a range of special products designed for high temperature brazing of steel and carbide components. These products contain nickel and or manganese and show improved wetting on tungsten carbide. C Bronze™ has good gap-bridging properties (0.025 to 0.75 mm) and offers excellent resistance to interfacial corrosion when used on ferritic or austenitic stainless steels. Due to the manganese content the alloy requires a furnace atmosphere with a dew point better than -40°C and if used for vacuum brazing a partial pressure of argon is required.
