RS PRO 0.71mm Tinned Copper Wire, 21 AWG 50.9m Reel

From RS Pro, a range of tinned copper wire supplied handy plastic spools. The annealed single strand copper wire benefits from a thin tin plating making the copper wires robust and resilient to moisture. Tinned copper wire is particularly useful where excellent electrical conductivity and thermal resistance is required, suitable for use as rewirable fuse links and shorting links. The RS Pro range of copper wire is available in various diameters and AWG sizes. All models are highly reliable and excellent quality.

• Excellent corrosion resistance
• Easy to solder
• Longer life than non-tinned copper wire
• Resistant to humidity and damp conditions
• Range of AWG (American Wire Gauge) sizes

Copper is the second most conductive metal in the world after silver. This makes the material extremely useful for the manufacture of conductive components. Tinned copper has many uses in the electrical wiring industry. Due to the materials efficient performance in humid or rainy climates copper wire is an extremely useful in applications where this is a discerning factor. Some of the most common environments are:

• Fuse links
• Panel wiring
• Industrial machinery cranes and forklift trucks
• Automation
• Telecommunications
• Marine applications

Being one of the top 5 most used metals around the world. It's no secret copper is widely regarding as the go to choice for wire in electronics. Due to the extremely convenient conductive properties, copper can be used as wires for anything, ranging from network cables up to advanced computer and mobile phone circuit boards.

Copper is the second conductive metal in the world after silver; therefore, there are no surprises as to why it has its place in the manufacture of conductive components. Due to the materials efficient performance in humid or rainy climates, copper wire finds appreciation in applications where this is a discerning factor.

We are proudly introducing our own branded RS PRO Tinned Copper Wire 50.9 m long, supplies as handy plastic spools. The item is widely used in power generation, transmission, distribution or telecommunications making the copper must-have wire in your household.
