Product Application:

Widely used and in high demand in the electrical and electronic industries, accounting for over half of total consumption. Used in various cables and wires, motor and transformer windings, switches, and printed circuit boards, among others. Extensively applied in the chemical industry for manufacturing vacuum pumps, distillation pots, brewing kettles, etc. In the construction industry, it is used for various pipes, pipe fittings, decorative components, and more. In the manufacturing of machinery and transportation vehicles, it is used to produce industrial valves and accessories, instruments, sliding bearings, molds, heat exchangers, and pumps.

Processing Techniques: Cutting, Polishing, Washing, etc.


 


Our Philosophy: Thin profit margins, quality control, and honest business operations.


 


Copper tubes available in materials such as H62, H63, H65, H68, T2, TP2, and oxygen-free copper tubes.


 


Our pipes are free of sand holes, have good eccentricity, stable chemical composition, can be straightened, stretched, and feature external and internal stripping, engraving, bending, and internal and external processing. The copper pipes have smooth inner and outer surfaces with precise dimensions, and the tolerance for inner and outer diameter can reach ±0.02.


 


Regarding pipe manufacturing: We specialize in producing high-quality copper pipes in various specifications, with dimensional tolerances of +/-0.02 for both inner and outer surfaces, ensuring smoothness, straightening, surface cleaning to remove oil. Quality is re-inspected, and we offer firm, semi-firm, and soft states for production, suitable for any processing.


Copper busbars are a type of copper strip with excellent electrical and thermal conductivity, corrosion resistance, and workability. They are suitable for welding and brazing.

Features and Application Scope


 


Excellent electrical and thermal conductivity, corrosion resistance, and machinability; suitable for welding and brazing. Contains minimal impurities that reduce electrical and thermal conductivity; trace amounts of oxygen have little impact on conductivity, thermal conductivity, and processing, but are prone to cause "hydrogen embrittlement." Not suitable for processing (annealing, welding, etc.) and use in high-temperature (e.g., >370℃) reducing atmospheres.
