40% SILVER BRAZING WELDING RODS MANUFACTURER

Specifications

HZ-Ag40BSn is a very widely used cadmium free silver brazing filler metal. It offers a combination of medium melting temperature and flow characteristics. It can be used to fill gaps that cannot be tightly controlled. These properties make it a popular choice as an alternative to the higher silver content or when changing from medium flow cadmium bearing products.

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 be noted that this filler metal contains tin and may be described as being hotshort. It should not be quenched from high temperatures (in excess of 300°C) 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.

Chemical Composition: Ag40, Cu, Zn, Sn, Ni.

Solidus:630°C

Liquidus:640°C

Brazing Temp:640-740°C

Product uses: 

It can be used to join most common engineering metals  copper, copper alloys including, brasses, bronzes, gun metal, nickel silver, aluminum 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.

Ring & Wire & Rod: 1kg/2kg
