2M Soft Copper Tube OD 4mm x ID 3mm for Cooling Hydraulic ToolDescription:Copper Tube It is mainly used for generators, busbars, cables, switchgear and other electrical equipment. Heat transfer, electrical conductivity and plasticity are good, but poor strength and hardness. Features: Fine ductility and corrosion resistance and weldability. They can be made into all kinds of semi-finished products and finished products by cold, hot forging. Excellent electrical conductivity, used in the production of wire, cable, brush (electrical), etc. Good thermal conductivity, used for the manufacture of magnetic instruments or counters that require anti-magnetic interference, such as compass, aeronautical instrument, etc. Wonderful plasticity, easy to process under hot and cold pressure, can be made into pipe, rod, wire, strip, strip, plate, film, etc. Specifications:Material: CopperOuter Diameter: 4mm/0.15"Inner Diameter: 3mm/0.11inchThickness: 0.5mm/0.02inchLength: 2m/78.74"Weight: 115g (Approx)Package Included:1 x Copper TubeNote:1.
