Corrosion Resistance
It exhibits good corrosion resistance in most non-oxidizing acids, alkalis, salt solutions, and various organic solvents, and can maintain structural integrity and functional stability under harsh conditions such as humidity and salt spray.
Electroplated Copper Busbar
Our company uses industry-leading high-end electroplating technology to precisely plate tin or silver on the surface of copper bars and rods, ensuring that the products have excellent conductivity, corrosion resistance, and solderability. Relying on ultra-precision plating control technology, the thickness of the electroplated tin layer can be precisely controlled to 5-12 microns, and the thickness of the electroplated silver layer ranges from 0.2-5 microns. The plating is uniform, dense, and has extremely strong adhesion.
We use a fully automated continuous electroplating production line, combined with an intelligent detection system and nanometer-level surface treatment technology, to ensure that the plating is smooth, uniform, durable, and stable, meeting the stringent requirements of the power, electronics, new energy, and high-end manufacturing industries, providing customers with globally leading high-quality electroplated copper bar solutions.
Tin-plated copper bars
The surface is plated with a tin layer to enhance oxidation resistance, corrosion resistance, and solderability, improving conductivity and service life. The thickness of the electroplated tin layer ranges from 2-12 microns and can be adjusted according to specific application needs. It is widely used in the power, electronics, rail transit, and new energy industries to ensure the long-term stability and reliability of products in complex environments.
Silver-plated copper bars
The surface is plated with a silver layer to improve conductivity, oxidation resistance, and corrosion resistance, and to enhance welding performance and wear resistance. The thickness of the electroplated silver layer ranges from 0.2-8 microns and can be customized according to needs. It is widely used in the power, electrical, electronics, high-end manufacturing, and new energy fields to ensure the excellent performance and long-term stability of products in demanding environments.
