The resulting composition showed a good rolling property from the cast ingot, and it rolled well to 40% work hardened and annealed condition. This alloy showed a bright yellow colour, and rolled well along a T-joint. In addition, it flowed well with F flux. This alloy was a suitable choice for gilding. But it has one disadvantage: it has poor dispersibility.
The Meta-Braze(tm) range of silver brazing alloys is a versatile choice for brazing. This type of silver alloy is suitable for joining most common engineering metals, including copper alloys. It is also suitable for brazing stainless steel and mild steel. However, it is not suitable for joining aluminium alloys. So, if you are looking for an alloy for a specific job, consider using one of the other options.
If you are planning to use the oxyacetylene process, you should use a reducing flame. Generally, a reducing flame will be more suitable, as the inner cone of the flame is too hot. Moreover, the joint clearance should be at least 0.002 inches. This is because the filler metal, a thin film, is stronger than the base metal. Moreover, it will help you relieve the stress after the brazing process.
The basic steps of silver brazing are the same as those for other brazing processes. A base metal is cleaned before applying the filler metal. Heat is then applied to the metal, and the brazed joint is then sealed and becomes very strong. The filler metal is not a pure silver alloy, but a mixture of various metals, with varying percentages of copper, nickel, tin, zinc, and other elements.feihongalloys.com
