Solder - lead and tin uses?

Answer 1

A solder is a metal or alloy that has a melting point range of 90 to 450 degrees Celsius (200 to 840 degrees Fahrenheit). The melting point range makes sure that the metal or alloy is easily handled at room temperature, can be melted to join other metallic surfaces when a moderate amount of heat is applied, and returns to a solid state when it cools down to make the joining permanent. Lead has a melting point of 327.46 degrees Celsius (621.43 degrees Fahrenheit) and therefore it can be used as solder. Mercury, however, has a melting point of -38.83 degrees Celsius (-37.89 degrees Fahrenheit) and it is liquid even at room temperature. Therefore it cannot be used as solder because a liquid that does not solidify cannot be expected to join two surfaces permanently.

Answer 2

One of the most important things to be aware of when it comes to solder is that, traditionally, solder was composed of mostly lead (Pb), tin (Sn), and a few other trace metals. This solder is known as leaded solder. As it has come to be known,lead is very harmful to human beings and can lead to lead poisoning when exposed to large amounts. With the adverse effects of leaded soldering known, some key individuals and countries decided it was best to not use leaded solder anymore. Lead-free solder is very similar to its leaded counterpart, except, as the name states, it contains no lead. Instead is is made up of mostly tin and other trace metals, such as silver and copper. This solder is usually marked with the RoHS symbol to let potential buyers know it conforms to the standard. For more visit solder.net

Tin/lead solder is easy and inexpensive to make, however it is not the only alloy used. Very low temperature solder alloys contain other metals like bismuth or gallium. Lead free solders may be pure tin or tin/antimony alloys. Some solder alloys contain small amounts of silver, copper, etc. to reduce the amount of metal from the work pieces that dissolves into the solder while making the joint.

Even simple tin/lead solder comes in many different alloys, from 10% tin 90% lead to 90% tin 10% lead, depending on the intended application. Electronic grade solder is 60% tin 40% lead, with low temperature eutectic solder being 63% tin 37% lead.

Answer 4

Solder containing lead and tin is commonly used in electronics and Plumbing applications for joining metals together. The lead content helps reduce the melting point of the solder, making it easier to work with, while the tin provides good conductivity. However, there are health and environmental concerns associated with the use of lead in solder, leading to the development of lead-free alternatives.

Answer 5

it depends on what solder it is but the most common solder has 50% tin and 50% lead

Answer 6

Lead free solder is required when connecting copper tubing used for drinking water. For electronic soldering as well as drain pipes in a home, solder with lead works very well.
