Oatey® 95/5 Lead Free Plumbing Wire Solder is a tin-antimony wire solder designed for use in plumbing applications where frequent and extreme temperature changes and vibrations occur. It is NSF listed for potable water applications and common applications also include refrigeration lines and cooling equipment.
What’s the difference between 50/50 solder and 95 5 solder?
The 50-50 tin-lead solder is suitable for moderate pressures and temperatures. For higher pressures, or where greater joint strength is required, 95-5 tin-antimony solder and alloys E and HB can be used.
What temp does 95 5 solder melt at?
Grade of the product is 95/5 tin-antimony. The tensile strength is at 4900. The melting temperature is 464°F (240°C).
Why is antimony used in solder?
Antimony is added to a tin-lead solder as a substitute for some of the tin. The antimony, up to 6%, increases the strength and mechanical properties of the solder. A word of caution, solders having a high antimony content should not be used on aluminum, zinc, or zinc-coated materials.
Why are copper fittings cleaned before soldering or brazing?
It cleans the metal making the solder stick to the fittings and pipe better it cleas oxides and oils. What is the purpose of flux? The longer that copper is kept at the higher brazing temperature, the greater the formation of copper oxide, and nearby valves may be overheated.
When soldering Why should flux be used?
The main purpose of the flux is to prepare the metal surfaces for soldering by cleaning and removing any oxides and impurities. Oxides are formed when metal is exposed to air and may prevent the formation of good solder joints.
What is the main difference between Type L and Type ACR copper tubing?
Type L copper is typically sold in straight lengths. ACR tubing is typically sold in a coil. Identify whether there are rubber or plastic caps on the end of the tubing. ACR is designed to be sold with no moisture inside the tube.
What is the melting point of silver solder?
A manufacturer can solder a component or components using, for example a high Lead (Pb) solder alloy. These alloys melt in the 300° range. He can then do a secondary solder using a Tin Silver solder (SnAg), which melts in the 220° range.
How much pressure will a solder joint hold?
A soldered four-inch Type L joint has a pressure rating of 440 psi. If the plumber in the field decides to braze that joint rather than solder it, the rating will be reduced to 293 psi — the annealed rating.
Can you melt solder with a lighter?
You can use anything that is able to heat a piece of metal up to the melting point of your solder (between 400°F / 200°C and 700°F / 370°C). Butane lighters work the best. But you can also use candles, oil lamps, alcohol burners, or even open camp fires.
Can you solder stainless steel?
The joint strength is generally lower than either brazed or welded joints. While the presence of a tenacious oxide film makes stainless steels more difficult to solder than carbon steels, stainless steels can be successfully joined by soldering, if the correct techniques are employed.
Is brazing hotter than soldering?
Because brazing involves higher temperatures than soldering, using an oxygen-acetylene torch is your surest bet because this gets hotter than a MAPP gas or propane torch, although for most small-to-medium jobs (thinner copper piping) a turbo torch should also work. Also remember that MAPP gas burns hotter than propane.
Is silver solder real silver?
What is silver solder and how does it differ from other types of solders? Silver solder is silver-based filler metal that has been used for years by welders. It’s a silver alloy with some other metals added in, which makes it stronger and able to take more punishment than typical aluminum or copper soldering wire.
What is silver solder made of?
Generally, silver solder contains: 65% fine silver. 20% copper. 15% zinc.
Where is Kester solder made?
Kester recognized the importance of being a global supplier in the electronics industry by establishing manufacturing facilities in Singapore (1969) and in Germany (1972) to better service the Asian and European markets, respectively. Kester was acquired by Element Solutions Inc. in December 2019.
