Types of Solder Buy lead-free solder that's designed for copper water pipes; you'll find it in the plumbing section of the store. Solder with lead is still available, but the lead can leach into your water supply, so don't use it.
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.
Is plumbing solder the same as silver solder?
solders. Hi Shaun, The Plumbers Solder is not "Silver Solder " at all. Real Silver Solder comes in very thin lengths of about a foot long and is used for soldering jewellery, rings etc. It is hard, not soft and takes much more heat to melt.

What is the mixture of solder?
Alloys commonly used for electrical soldering are 60/40 Sn-Pb, which melts at 188 °C (370 °F), and 63/37 Sn-Pb used principally in electrical/electronic work. The latter mixture is a eutectic alloy of these metals, which: has the lowest melting point (183 °C or 361 °F) of all the tin-lead alloys; and.
What is solder and its composition?
Solder is a metal alloy usually made of tin and lead which is melted using a hot iron. The iron is heated to temperatures above 600 degrees fahrenheit which then cools to create a strong electrical bond.
Leaded Compounds
Soft soldering wire that contains lead is comprised of combinations of tin, lead, silver, cadmium and copper. Combinations of tin and lead are most common, in ratios of 60 percent tin/40 percent lead; 63 percent tin/37 percent lead; and 50 percent tin/50 percent lead.
Lead-Free Compounds
Lead-free soldering wire is comprised of various combinations of tin, copper, silver and antimony. Pure tin wire has the highest melting point of 449 degrees. Other combinations of metals melt in a range between 419 and 441 degrees.
Uses
Lead-free soldering wires include varieties with "no clean" flux that are used in electronics. No clean flux does not leave a residue of foreign particles after fusing. Stainless steel requires an acid core soldering wire. Rosin core wire creates bonds with extra strength.
Cost
Leaded solder wire is less expensive than lead-free solder wire. Prices vary according to the metallic content of each alloy, and the size of the spool.
What is oatey bar solder?
COMMON APPLICATIONS Oatey Bar Solder is a general purpose alloy of 50% tin and 50% lead. 50/50 Bar Solder is most commonly used for copper drain piping, tin plating, seaming joints and sheet metal. 50/50 Bar Solder can be used to solder copper and most copper alloys including lead, nickel alloys and steel.

What is soldering metal?
Solder is any soft metal used to join two harder metals together via melting and fusing to the parts of the joint. Many different alloys and pure, elemental metals are used for soldering. Many of the alloys combine some other metal with lead, as lead is very soft and is easy to shape.
Is lead solder the same as tin?
Although lead is the most common component of the various kinds of solder, it is not the only kind of metal commonly used. Tin is also a very common component of solder alloys, as it is easy to shape, is stronger than lead, and lacks lead's toxic properties. Silver and copper are other common metals, especially for brazing, ...
What is the melting point of soft solder?
Soft solder typically has a melting point range of 90 to 450 °C (190 to 840 °F; 360 to 720 K), and is commonly used in electronics, plumbing, and sheet metal work. Alloys that melt between 180 and 190 °C (360 and 370 °F; 450 and 460 K) are the most commonly used. Soldering performed using alloys with a melting point above 450 °C (840 °F;
Why is lead 50/50 solder?
Historically, a higher proportion of lead was used, commonly 50/50. This had the advantage of making the alloy solidify more slowly. With the pipes being physically fitted together before soldering, the solder could be wiped over the joint to ensure water tightness.
How are intermetallics formed?
Many different intermetallic compounds are formed during solidifying of solders and during their reactions with the soldered surfaces . The intermetallics form distinct phases, usually as inclusions in a ductile solid solution matrix, but also can form the matrix itself with metal inclusions or form crystalline matter with different intermetallics. Intermetallics are often hard and brittle. Finely distributed intermetallics in a ductile matrix yield a hard alloy while coarse structure gives a softer alloy. A range of intermetallics often forms between the metal and the solder, with increasing proportion of the metal; e.g. forming a structure of Cu-Cu 3 Sn-Cu 6 Sn 5 -Sn. Layers of intermetallics can form between the solder and the soldered material. These layers may cause mechanical reliability weakening and brittleness, increased electrical resistance, or electromigration and formation of voids. The gold-tin intermetallics layer is responsible for poor mechanical reliability of tin-soldered gold-plated surfaces where the gold plating did not completely dissolve in the solder.
What is solder wire?
For electrical and electronics work, solder wire is available in a range of thicknesses for hand-soldering (manual soldering is performed using a soldering iron or soldering gun ), and with cores containing flux. It is also available as a room temperature paste, as a preformed foil shaped to match the workpiece which may be more suited for mechanized mass-production, or in small "tabs" that can be wrapped around the joint and melted with a flame where an iron isn't usable or available, as for instance in field repairs. Alloys of lead and tin were commonly used in the past and are still available; they are particularly convenient for hand-soldering. Lead-free solders have been increasing in use due to regulatory requirements plus the health and environmental benefits of avoiding lead-based electronic components. They are almost exclusively used today in consumer electronics.
How do impurities enter the solder reservoir?
Impurities usually enter the solder reservoir by dissolving the metals present in the assemblies being soldered . Dissolving of process equipment is not common as the materials are usually chosen to be insoluble in solder.
What is solder flux used for?
They are almost exclusively used today in consumer electronics. Plumbers often use bars of solder, much thicker than the wire used for electrical applications, and apply flux separately; many plumbing-suitable soldering fluxes are too corrosive (or conductive) to be used in electrical or electronic work.
Why is lead free solder less desirable?
Lead-free solder may be less desirable for critical applications, such as aerospace and medical projects, because its properties are less thoroughly known.
