The difference between ordinary copper stranded wire and tinned copper stranded wire is mainly reflected in the following aspects:
one Material: Ordinary copper stranded wire is made of pure copper or oxygen free copper, while tinned copper stranded wire is treated with tin on the surface of copper based on ordinary copper stranded wire. Tin plating can improve the oxidation resistance and welding performance of copper stranded wires.
two Appearance: The surface of ordinary copper stranded wire is smooth and red yellow in color; The surface of the tinned copper stranded wire is silver white and glossy.
three Performance: Tinned copper stranded wire has better oxidation resistance and welding performance compared to ordinary copper stranded wire. The tin coating can effectively prevent oxidation of copper stranded wires in harsh environments such as high temperature and humidity, and extend their service life. At the same time, the tin coating can also improve the welding performance of copper stranded wires during the welding process, reducing welding defects.
four Application field: Ordinary copper stranded wire is widely used in fields such as power transmission, communication lines, electrical equipment, etc; Tin plated copper stranded wire, due to its excellent oxidation resistance and welding performance, is more suitable for electrical equipment, submarine cables, lightning protection and grounding engineering in high temperature, high humidity, and corrosive environments.
five Price: Due to the addition of tin plating treatment in the production process of tinned copper stranded wire, its cost is relatively high and the price is also more expensive than ordinary copper stranded wire.
In summary, there are certain differences between ordinary copper stranded wire and tinned copper stranded wire in terms of material, appearance, performance, application fields, and price. In practical applications, appropriate copper stranded wires should be selected based on specific needs and scenarios.
