DESCRIPTION

Tinned Copper Wire, also known as Tin-plated Copper Wire, is a type of wire where a layer of metallic tin is plated onto the surface of a copper wire. This treatment enhances the corrosion resistance and oxidation resistance of the copper wire, thereby extending its service life. Tinned copper wires are widely used in electronics, electrical engineering, and related fields due to their soft material, good electrical conductivity, and other advantages.

The main advantages of tinned copper wire include:
1. Enhanced Corrosion Resistance: The tin layer prevents the copper wire from oxidizing in the air, avoiding the formation of patina (chemical formula Cu2(OH)2CO3), which has poor electrical conductivity.
2. Oxidation Resistance: The tin layer effectively stops further oxidation of the copper, maintaining its good electrical conductivity.
3. Good Soldering Properties: Tinned copper wire has good solderability, making it suitable for welding electronic components and printed circuit boards.
4. Improved Stability: The tin plating enhances the stability of the copper wire, including wear resistance, corrosion resistance, and electromagnetic shielding.

According to the search results, the Chinese national standard GB/T 4910-2022 specifies the standards for tinned round copper wire, while GB/T 37568-2019 covers the standards for tinned copper and copper alloy strips. These standards provide guidelines and direction for the production and application of tinned copper wire.
