Seamless Aluminum Tube Pipe 1050 1060 1070 1035 1085 Alloy H112
Seamless aluminum tubes are made from 1050, 1060, 1070, 1035, and 1085 alloys. Manufacturers use extrusion or drawing to produce these tubes. The process creates tubes without any weld seams. These alloys belong to the 1000 series and contain commercially pure aluminum. The tubes are usually supplied in the H112 temper.
These seamless aluminum tubes offer excellent conductivity and corrosion resistance. They also provide good formability and lightweight strength. Engineers use them in electrical systems such as busbars and transformer tubing. They are also common in heat exchangers, solar heating, and radiator coils. Industrial plants use them for non-corrosive chemical transport. HVAC systems, automotive cooling lines, and architectural structures also rely on these tubes.
