In brazing the joint is made by heating the base metal red hot and filling the gap with molten metal whose melting temperature is typically above 450°C 450 C but below melting temperature o base metal. The filler metals are generally copper alloys. Cu-Zn Cu Zn and Cu- Cu Ag alloys are used for brazing because they form alloy with iron and have good strength. Various brazing joints are shown in figure. figure
