Types Of Brazing Alloys
Aug 06, 2017

           The invention relates to a nickel base hard brazing alloy. The alloy has good wettability to molten brazed material and has excellent corrosion resistance and high strength. The alloy is used for welding two pieces of metal such as stainless steel. The alloy contains CR, the dosage is 25-35 weight%, P, the dosage is 4-8 weight%; Si, its dosage is 3-6 weight%, and the total of P and Si is 9-11.5 weight%; also contains at least one of the selected from Al, Ca, Y and lean metal mixtures, with a dosage of 0.01-0.10 weight%, and residual ni and unavoidable impurities.Brazing Alloy

           A high temperature brazing alloy of cobalt base comprising the following components (by weight): Nickel is about 8. 5%-12. 5%, chromium about 24%-40%, tungsten about 0%-9%, carbon about 0. 03%-0. 6%, boron about 0. 01%-3. 5%, si about 0. 1-11%, manganese up to about 2%, hafnium about 0. $number, Tantalum, ca. 0. 1%-8%, zirconium ca. 0%-1%, titanium 0%-CA 1%, margin is cobalt. The brazing alloy is used to repair the heat of the cobalt-based impeller machine parts.Brazing Alloy

           The invention relates to a brazing metal comprising a cobalt-chromium-palladium base alloy, which comprises a transition metal such as cobalt, nickel, tungsten, molybdenum and some non-metallic elements; more specifically, it relates to a multi-component alloy containing cobalt, chromium, palladium, nickel, tungsten, molybdenum, boron and silicon, which is particularly advantageous for brazing metals that produce high strength, high antioxidant resistance, high temperature resistance and corrosion resistance at high temperatures. The alloy of the present invention is composed of a chemical formula: Cranibwcpddsiebfcobal. (plus accidental impurities), where subscript "a", "B", "C", "D", "E" and "F" as the atomic percentage, "a" value of about 15-22, "B" value is about 0-20, "C" value is about $number, "D" value is about 1-10, "E" value is about 5-12, and "F" value is about 5-12, "Bal" is the equilibrium value to make the total percentage reach 100%.Brazing Alloy
