Hard alloy brazing material

    DESCRIPTION:

    There is many kinds of cemented carbide solder, the largest is the copper base solder and silver based solder.Pure copper-based solder of hard alloy has good wettability, but must be under the condition of vacuum brazing, can achieve the best effect.Silver based solder comprehensive performance is better than that of copper based-filler metals, silver based solder to prevent brazing crack.

    APPLICATION:

    Used extensively for brazing tungsten carbide tips on woodcutting,metal cutting and mining tools.

    Customer’s required chemical composition can be customized.
