Specification Brand : Rubber-Cal BulletPoint1 : [Durable Copper Tube] - Made of copper material, which is lightweight, with high strength, good thermal conductivity, corrosion resistance, high-temperature resistance, ductility, and weather resistance. Can be used on various occasions. BulletPoint2 : [Application] - Commonly used in machinery, DIY projects, hobbies, crafts, building models, building decorations, frames, industrial, gardening products, and so on. BulletPoint3 : [Weldable & Cuttable] - Copper tubing can be welded and processed to different lengths according to your needs by using the right equipment. BulletPoint4 : [Seamless Construction] - The interior is smooth without seams and is available in an extruded structural or a drawn seamless copper round tube for precision applications. BulletPoint5 : [Warm Note] - The surface of the copper tube is easy to be oxidized and it will have a little oxidation (not rustiness), but it does not affect the use.
