Bulk orders welcome. At New Eagle Industrial Corporation, we supply a comprehensive range of Copper Seamless Tubes manufactured as per ASTM B68, ASTM B75, and ASTM B251 standards. Our tubes are engineered for superior thermal conductivity, corrosion resistance, dimensional stability, and long service life.ASTM B68 covers cold-drawn seamless copper tubes designed for water lines, fuel/oil lines, plumbing, and general engineering. Cold drawing ensures smooth internal surfaces, tight tolerances, and high pressure resistance. Available in C12200 and C10200, these tubes offer strong corrosion resistance, weldability, and excellent thermal conductivity.ASTM B75 defines seamless copper tubes produced from high-conductivity alloys like C12200 and C10200, primarily used in heat exchangers, condensers, HVAC units, and industrial cooling systems. Precision drawing and annealing improve ductility, surface finish, and uniform wall thickness, making them ideal for bending and forming operations.ASTM B251 specifies general-purpose seamless copper and copper-alloy tubes supplied in multiple tempers and hardness levels. These tubes are widely used in marine hardware, electrical systems, industrial piping, and structural components due to their high strength, consistent mechanical properties, and excellent resistance to seawater and industrial chemicals.With competitive pricing, ready stock, and global export capabilities, New Eagle Steel remains a trusted source for high-quality copper seamless tubes. 90/10 Copper Seamless Tubes – Technical Specifications StandardASTM B68 / ASME SB68 ASTM B75 / ASME SB75 ASTM B251 / ASME SB251 Grade90/10, 70/30 Manufacturing ProcessSeamless / Cold Drawn Outer Diameter Range (OD)6 mm…
