15 silver brazing rod melting point.

Does anyone know of a chart that has all the melting points of solder say 50 50 or the melting point of the silver solders that we use in our field the reason i m posting is because out lab manual asked for specific temp s. At its liquidus temperature the. This means that if you try to weld copper melting point 1981 f 1083 c to steel melting point 2500 f 1370 c you must employ rather sophisticated and expensive welding techniques. Silver brazing is a joining process whereby a non ferrous filler metal alloy is heated to melting temperature above 800 f and distributed between two or more close fitting parts by capillary attraction.

Soldering differs from brazing in that it takes place at temperatures below 450 c although both processes occur below the melting point of the metals being joined. The percentage is the percentage of silver content in the rod. They also have features of high mechanical strength fine plasticity electrical conductivity and corrosion resistance. Silver brazing frequently called hard soldering or silver soldering is a low temperature brazing process with rods having melting points ranging from 1145 to 1650ºf 618 to 899ºc.

This is considerably lower than that of the copper alloy brazing filler metals. This composition allows it to flow more quickly and deeply. The only real reason to use lower silver levels is the cost and the difference can have many techs and owners wondering what the difference is. Brazing filler metals have a melting point above 450 c but below the melting point of the metals being joined.

Used in food equipment. The most common rods used for typical hvac brazing are 0 5 and 15 with several other levels mixed in there. It is a eutectic alloy having the same solidus and liquidus temperatures. Silver brazing filler metals have low melting point good wettability and filling performances.

Slight tendency to liquate. Sil fos 18 has the highest silver content in the sil fos family but it has the lowest melting point. The total ease of joining dissimilar metals.
