For brazing titanium alloys. Available as amorphous foil. 17: Zr 83: Zr 56 V 28 Ti 16: 1193/1250 [5] – For brazing titanium alloys. Available as amorphous foil. 16: Zr 56 V 28: Ag 57 Cu 38 Ti 5: active 775/790 [5] – Active alloy. Can be used for brazing ceramics, e.g. silicon nitride. Titanium forms an interfacial layer with Si 3 N 4 ...
For manual brazing, wire and rod forms are generally used as they are the easiest to apply while heating. In the case of furnace brazing, the alloy is usually placed beforehand since the process is usually highly automated. [14] Some of the more common types of filler metals used are Aluminum-silicon; Copper; Copper-silver; Copper-zinc
CuSil is a tradename for an alloy of 72% silver and 28% copper (± 1%) marketed by Morgan Advanced Materials. It is a eutectic alloy primarily used for vacuum brazing . [ 1 ] CuSil should not be confused with the similarly named Cusil-ABA, which has a different composition (Ag – 63.0%, Cu – 35.25%, Ti – 1.75%)
Soldering performed using alloys with a melting point above 450 °C (840 °F; 720 K) is called "hard soldering", "silver soldering", or brazing. In specific proportions, some alloys are eutectic — that is, the alloy's melting point is the lowest possible for a mixture of those components, and coincides with the freezing point.
Of all the brazing alloys, silver solders have the greatest strength and the broadest applications. [5] Specialty alloys are available with properties such as higher strength, the ability to solder aluminum, better electrical conductivity, and higher corrosion resistance. [6]
Brazing with silver-based brazing alloys may require first electroplating the Glidcop part with either copper or nickel. [6] The copper plating can be done with a copper cyanide solution; other solutions may not work. Gold-based brazing alloys like 3565 AuCu and 5050 AuCu, can be used in a dry hydrogen atmosphere.
