What is Sil-Fos used for?

Sil-Fos alloys are commonly used in the HVAC/R and plumbing industries because of their ability to join copper to copper without the use of flux. These alloys will help produce consistent, quality joints while saving on materials plus reducing time and process costs.

What is the melting point of Sil-Fos?

The melting point of copper (Cu) alloy UNS C12200 is 1,981°F/1082°C. As such, the filler metals for soldering and brazing copper and copper alloy tube and fittings must have melting temperatures below this temperature. Above that temperature, the process is brazing.

What is Sil-Fos Rod?

This silver brazing alloy is ideal for copper-to-copper joints the phosphorus in the Sil-Fos serves as the fluxing agent and no separate flux is necessary. Use to join copper, brass and bronze products. Sil-Fos 15 contains 80%Copper/ 15%Silver/ 5%Phosphorous.

Which is the best material to use on HVAC pipe brazing?

When brazing copper the best choice is always sil-phos. Only use silver braze on the brass and steel joints. This compound is very expensive so it is not commonly used when sil-phos can be used.

What is Sil-Fos made of?

The Original Sil-Fos Sil-Fos alloys combine silver (Ag), copper (Cu), and phosphorous (P) to produce consistent, quality joints while saving on materials plus reducing time and process costs.

What is the melting point of 15 silver solder?

The 15 per cent silver brazing alloy material has lower melting point (645°C–700°C) and a higher tensile strength of 700MPa. The advantages of the lower melting point and higher tensile strength of the silver brazing alloy brazing material results in its wide use in refrigeration work.

What is the melting point of silver?

961.8 °C
Silver/Melting point

What is Sil Fos made of?

Is MAPP gas hot enough to braze?

Genuine MAPP gas can be used in combination with oxygen for heating, soldering, brazing and even welding because of its high flame temperature of 2925 °C (5300 °F) in oxygen.

Can you braze refrigerant lines with MAPP gas?

We use MAPP gas with a shield attached it is quite good up to 7/8 copper tube only and the braze joint needs to be away from any large mass of metal as the heat can be drawn away just as fast as you apply it.
