What does solder consist of?

Answer 1

Solder has traditionally been a tin lead alloy, but there are many variations depending on the application:

• jeweler's solder or silver solder, has always contained silver to prevent the solder from dissolving silver and/or gold from the item being soldered
• other low melting point metals are sometimes added to make low melting point solder
• pure tin solder is sometimes used to eliminate toxic lead
• etc.

Solder sold in the form of wire is sometimes hollow with a core filled with flux paste to make soldering easier without the need for extensive precleaning of the work so that the solder properly wets. For Plumbing purposes (where the work can be rinsed afterwords) the flux paste is acidic and very corrosive, for electronics work the flux paste is a rosin.

Answer 2

Lead and tin were once the metals of choice for solder. They offered high strength, were easy to work with and were stable.

Recent legislation in most developed countries have are are about to restrict lead in solder. Solder now usestin, copper and silver with some other trace elements. Although it has removed the lead, it has a higher melting point and it is more difficult to use well.

Answer 3

Tin and antimony Or tin and lead Or tin lead and rosin ==

Answer 4

lead and tin, bismuth and sometimes other metals

Answer 5

A solder is just like the filament of an electric bulb which gets heated up with more power supplied

Answer 6

Solder is typically composed of lead or tin. At a higher heat, brass or silver can be used. Solder is used for joining other metals together.

Answer 7

No, solder is made of the two elements lead and tin.

Answer 8

Lead and Tin

Answer 9

Germanium
