Copper Alloy Tube

Yantai Wanlong Vacuum Metallurgy Co., Ltd. is one of the most reliable manufacturers and suppliers of copper alloy tube in China. With abundant experience, we are committed to providing high quality customized products for global clients. Welcome to buy bulk premium copper alloy tube from our factory.

We supply a full range of large-diameter copper tubes, Including CuCrZr tubes and pure copper tubes, etc.Adopting exclusive vacuum casting technology, combined with hot extrusion seamless forming, multi-pass rolling, aging heat treatment and full-process non-destructive testing, our products optimize the internal micro structure and eliminate common defects such as shrinkage cavities, inclusions and pores. The tubes feature uniform wall thickness, smooth inner and outer surfaces, and high dimensional accuracy, delivering excellent pressure resistance, structural stability and superior mach inability.

Copper tubes exhibit excellent electrical and thermal conductivity. Brass and nickel-brass tubes are resistant to seawater corrosion, scaling, and oxidation; chromium-zirconium copper tubes combine high strength and high conductivity with superior resistance to high-temperature softening, as well as fatigue resistance.

Pure copper tubes are mostly used in power and new energy sectors, hollow sleeves for large motors, hollow bus bars, metallurgical cooling jackets, fresh water heat exchange, vacuum and RF cavities. They are also applied in HVAC systems, medical gas pipelines and high-end building water supply systems to meet the requirements of electrical conduction, heat dissipation and clean fluid transmission. CuCrZr copper tubes combine ultra-high electrical and thermal conductivity with excellent high-temperature softening resistance, maintaining stable performance, anti-fatigue capability and deformation resistance under high-temperature and heavy-load conditions. Our large-diameter copper tubes are widely used in high-end industrial fields including marine engineering, seawater desalination, nuclear power and metallurgical cooling systems, chemical heat exchange equipment, new energy conductive components, automotive welding equipment and precision heat dissipation systems.
