Inox Steel India supplies a wide range of Copper, Brass and Bronze Seamless Tubes used across industries that require excellent thermal conductivity, corrosion resistance, machinability, and long-term reliability.
Manufactured as per ASTM B68, ASTM B111, ASTM B135 and ASTM B359, these non-ferrous seamless tubes deliver consistent performance in HVAC systems, heat exchangers, desalination plants, marine cooling circuits, chemical processing lines, instrumentation and architectural applications.
Copper and copper-based alloys are preferred when a combination of heat transfer efficiency, smooth internal surface, antimicrobial performance, and corrosion resistance is required.
These seamless tubes ensure uniform wall thickness, enhanced workability, and exceptional durability across a wide variety of engineering and fluid-handling applications.
These tubes are produced via extrusion, cold drawing, annealing and solution-based processes, ensuring precise dimensional accuracy and clean internal surfaces.
Backed by certified raw materials and stringent testing, Inox Steel India supplies non-ferrous seamless tubes across India, GCC, Africa, Southeast Asia and Europe.
Copper-based alloys are widely used where thermal conductivity, corrosion resistance, smooth internal flow, and clean fluid transfer are essential.
CuNi alloys offer unmatched seawater resistance, while Brass and Bronze serve high-machinability and mechanical strength requirements.
