USES: Silvering Sn.Ag, is a special alloy made of TIN-SILVER, lead free, non toxic, low melting point, ideal for joining stainless steel, copper, bronze, brass and ferrous metals (iron, stainless steel, nickel), pewter, zamak, babbitt, ideal for welding: stainless steel pipelines, food industries, refrigeration, air conditioning, plumbing, medical and mechanical systems of high resistance (16.000 PSI) on the joint. On common welding of low resistance: Tin-Antimony and Lead-Tin it is about 7.000 PSI.
APPLICATIONS: On copper joints, stainless steel and dissimilar metals, thin or delicate parts that can be damaged by an excess of heat. Ideal for joining copper pipelines, stainless steel on food transportation, liquids and gases (oxygen, propane, acetylene, air, freon, etc.), on refrigeration. Ensuring a better reliability than with the Lead-Tin, Tin-Antimony welding, having a better resistance, doesn’t oxidizes, more flexibility, supporting more vibrations and tensions produced by heat.
In addition, it leaves joints resistant to corrosion, which do not become dirty and remain shining. Mostly used for cooking utensils, dishes made of silver.
NOTE: The Tin-Antimony alloys are not recommended for vibration joints. They tend to leave a powder which will break it.
PROCEDURE: Clean perfectly the surfaces to join, add the flux (cream or powder) FLUX SILVERING SnAg, on the base metal and on the welding, preheat the base metal with flame or an electrical tweezers and apply the welding indirectly with heat. Melting the welding by the heat of the piece and not by that of the torch. Apply even more flux with a brush over the melted welding.
TECHNICAL CHARACTERISTICS: Welding of a great fluidity and penetration given by its capillarity. Adhesion at low temperatures. It is times better the conventional Tin-Lead welding, does not oxidize, leaving extremely resistant joints with a better flexibility to support vibration. Thin flow at a low temperature.
Ideal for gas welding torch Gas-Air or electrical tweezers, on joints that are difficult to warm up such as copper pipelines, due to its low melting point at 220° Celsius. (430°F).
