15 Silver Brazing Rod Melting Point

Brazing filler metals have a melting point above 450 c but below the melting point of the metals being joined.

15 silver brazing rod melting point.

Lowest melting point cadmium free silver alloy. The percentage is the percentage of silver content in the rod. 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. Silver brazing filler metals have low melting point good wettability and filling performances.

This composition allows it to flow more quickly and deeply. At its liquidus temperature the. The most common rods used for typical hvac brazing are 0 5 and 15 with several other levels mixed in there. Sil fos 18 has the highest silver content in the sil fos family but it has the lowest melting point.

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. They also have features of high mechanical strength fine plasticity electrical conductivity and corrosion resistance. Low zinc content minimizes issues with prolonged or repeated heating. 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.

Slight tendency to liquate. This silver brazing alloy is. This is considerably lower than that of the copper alloy brazing filler metals. It is a eutectic alloy having the same solidus and liquidus temperatures.

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. Used in food equipment. 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.
