Silver solder 1.5mm 20% 1kg
Silver Solder Bare Brazing Rods offer a combination of medium melting temperature and flow characteristics. It can be used to fill gaps that cannot be tightly controlled. It is widely used as a general purpose silver brazing filler metal as well as in joining copper to steel in refrigeration pipe work. It should not be quenched from high temperatures and care should be taken when it is used to braze components with widely differing coefficients of thermal expansion as in both cases cracking of the joints may occur. Optimum joint gaps at brazing temperature are 0.075-0.2mm.
