What is solder?
Solder is a metal alloy with a low melting temperature point. It is used to permanently join two metals with a higher melting point. Soldering is a process commonly used in the electronics industry for PCBs, jewellery manufacturing and pipework in plumbing.
Solder is to be used alongside a soldering iron for hand soldering.

What forms of solder are there?
• The majority of solder comes in wire form. There are a range of wire diameters available to suit various applications and joints.
• Solder granules are ideal for soldering machines and tinning crucibles. They are small pellets of solder popular for jewellery making too.
• Paste solder is ideal for use in printed circuit boards (PCBs) and connecting surface mount electronic components. It is a sticky paste which is applied to a board by printing or painting.

Solder is made using a mixture of metals. A popular combination is 60/40 solder; 60% tin and 40% lead. There are other %s of tin and lead available too. Silver is also used in solder for higher temperatures to create stronger joints, also known as silver soldering, hard soldering or silver brazing.
