An alloy of lead, tin, copper, and aluminum.
How To Make Solder. Plumber's wiping solder, for use with the ladle and the soldering cloth, is made up by melting together pure lead and block tin in the proportion of 2 pounds of lead to 1 pound of tin. Plumber's fine solder is made of about equal parts of those two metals. Strip solder-used with the copper-bit-is made in the proportion of 2 pounds of tin to 3 pounds of lead. Gas-fitter's solder may be made in the proportion of 8 pounds of tin to 9 pounds of lead, tinsmith's copper-bit solder is 1 pound Traditional solder that used to be used for soldering in the electronics industry used to be a mixture of tin and lead. Different types of solder are used for different purposes. Solder is of course used in plumbing. The type of solder used for electronics usually contains 60% tin and 40% lead. This is often known as 60/40 solder. It is what is termed a Eutectic Mixture. Although this is a chemical term, basically this type of mixture melts at a temperature well below that which might normally be expected.  Solder is a fusable metal alloy Solder is a metal alloy used to join metal workpieces and having a melting point less than that of what you're joining. Solder is used … to connect electrical components together so they'll work in a circuit. It is also used for joining plumbing fixtures and pipes and fittings. Soldering wire is made from an alloy of tin and lead. Typically, it  is 60% tin, and 40% lead. Soft solder is made of an alloy of tin and lead. Hard solders (for jewelry work) a usually made mainly our of the metal being worked (e.g. silver). Tin and Lead There are many different metals in solder. Some of the metal an  individual may find in solder are: lead, tin, copper, and aluminum. answ2. Solders are still mad … e of alloys of tin and lead, and with the addition of other metals to provide particular performance. Some solders contain no lead, and there exist solders of SnZn for soldering aluminum. Soldering wire is made from an alloy of tin and lead. Typically, it  is 60% tin, and 40% lead. Soft solder is made of an alloy of tin and lead. Hard solders (for jewelry work) a usually made mainly our of the metal being worked (e.g. silver). Solder is made out of a couple different metals. It used to be made  of tin and lead, but due to the negative health effects of lead,  many are made with tin and other metal … s like silver. Soldering wire is made from an alloy of tin and lead. Typically, it  is 60% tin, and 40% lead. Soft solder is made of an alloy of tin and lead. Hard solders (for jewelry work) a usually made mainly our of the metal being worked (e.g. silver). Best Answer: Tin/lead solders are commercially available with tin concentrations between 5% and 70% by weight. The greater the tin concentration, the greater the solder’s tensile and shear strengths. At the retail level, the two most common alloys are 60/40 Sn/Pb and 63/37 Sn/Pb.  Soft solder is typically thought of when solder or soldering is mentioned, with a typical melting range of 90 to 450 °C (190 to 840 °F). It is commonly used in electronics, plumbing, and assembly of sheet metal parts. Manual soldering uses a soldering iron or soldering gun. Lead-tin solder layers on copper leads can form copper-tin intermetallic layers; the solder alloy is then locally depleted of tin and form a lead-rich layer. The Sn-Cu intermetallics then can get exposed to oxidation, resulting in impaired solderability. Report Abuse. Solder is a lead based alloy with a low melting temp. Used to bind two pieces of tin, iron, copper, or steel. Joining copper pipes and circuit board connections are where it's most commonly used. Solder is a mixture of tin and lead. It melts around 300 degrees and is used to fasten metal together. It adheres to Silver and Copper. Electronic circuits use solder to attach the individual components to a printed copper pattern on the circuit board. Plumbers use solder to seal copper pipes together.
