1.5mm 40% Silver Solder Rods (S0ld either in single rods or 1KG packs) Unfluxed Kilo contains 123 rods Fluxed Kilo contains 72 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. Product uses: used to join most common engineering metals – copper, copper alloys including, brasses, bronzes, gun metal, nickel silver, aluminium bronze, copper nickel, steels including, mild, carbon, tool steel, stainless steels, low alloy steel. This alloy is not normally recommended for brazing tungsten carbide and PCD segments where lower melting or nickel / manganese containing silver brazing filler metals are often preferred.
