WHAT ARE SILVER BRAZING ALLOYS ?
A.- Silver brazing alloys comprise a wide range of silver bearing compositions normally containing copper, zinc, phosphorous and in many cases, cadmium. For certain applications, limited additions of other elements, e.g. nickel, tin, etc. may be introduced. These alloys exhibits high tensile strengths at room temperature 390-540 N/mm2 (25/35 tons. f/in2) with relatively low melting points (600-850 c) and are capable of joining a wide variety of parent metals, both ferrous and non-ferrous. This includes most commonly available engineering materials and many specialized alloys with the general exception of those melting under approximately 650 C (e.g. aluminum and zinc based alloys.
