Soldering Wire – 50Gms ( Solder Wire )
- Solder is a fusible metal alloy used to create a permanent bond between metal workpieces. The word solder comes from the Middle English word soudur, via Old French solduree and soulder, from the Latin solidare, meaning “to make solid”.
- Solder that is useful in making electrical connections between electronic components also usually has favourable electrical characteristics.
- Soft solder wire ( soldering wire) typically has a melting point range of 90 to 450 °C (190 to 840 °F; 360 to 720 K) and is commonly used for electronics, plumbing, and sheet metal work. Manual soldering uses a soldering iron or soldering gun. 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; 720 K) is called “hard soldering”, “silver soldering”, or brazing.
- In electrical work, soldering wire if the joint is disturbed in the pasty state before it has solidified totally, a poor electrical connection may result; use of eutectic solder reduces this problem.
- The pasty state of a non-eutectic solder can be exploited in plumbing, as it allows moulding of the solder during cooling, e.g. for ensuring watertight joint of pipes, resulting in a so-called “wiped joint”.
