Copper Sq / Rect Tube

Copper Square & Rectangular Tube | High Thermal & Electrical Conductivity

Copper Square and Rectangular Tubes are precision-engineered profiles produced from high-purity copper, offering outstanding material stability, corrosion resistance, and long-term durability. Manufactured with uniform wall thickness, smooth surfaces, and tight dimensional tolerances, these tubes provide reliable mechanical performance and excellent workability for fabrication processes such as bending, cutting, forming, and welding.

The inherent properties of copper—including high thermal conductivity, high electrical conductivity, and excellent resistance to water, chemicals, and atmospheric corrosion—make these tubes suitable for demanding environments where performance, conductivity, and structural integrity are critical.

Copper square and rectangular tubes are available in a wide range of grades, tempers, and sizes, allowing customization to meet specific strength, conductivity, or processing requirements. Their refined appearance, stable mechanical characteristics, and versatility make them an ideal material choice for precision components, functional structures, and high-quality design elements.
