描述
Product Overview
The tin-plated copper strip is a specialized busbar product for power transmission, which undergoes tin plating on the surface of high-purity, oxygen-free copper strips. It combines the excellent electrical conductivity of copper with the anti-oxidation, corrosion resistance, and easy-to-solder properties of the tin coating. It is an indispensable key conductive component in industries such as high- and low-voltage power distribution, new energy, and industrial automation.
Core features of the product.
1. Exceptional conductivity: The base material consists of 99.95% or higher oxygen-free copper. The tin coating does not affect the conductivity efficiency and, at the same time, can reduce the contact resistance at the connection points, thereby decreasing energy losses.
2. Long-lasting anti-oxidation and corrosion resistance: The evenly dense tin coating acts as a barrier against air, moisture, and corrosive substances, effectively preventing the oxidation and discoloration of copper strips. It can maintain stable operation over an extended period in humid, high-salt-mist, and industrial corrosive environments.
3. Stable and reliable coating quality: Utilizing advanced continuous tinning technology, the coating is uniform in thickness and has strong adhesion. It does not peel or detach during bending and stamping processes, meeting the requirements for subsequent processing and installation.
4. Customized services for all scenarios: We support customization for thicknesses ranging from 0.5 to 120 mm and widths ranging from 10 to 600 mm. We can provide tailored product solutions with different tin-plating thicknesses and various manufacturing processes based on customer requirements.
