20mm & above Gunmetal Hollow Bar, Polished

Pearl Overseas is a reliable organization engaged in Manufacturing, Suppling, Exporting & Importing for Gunmetal Hollow Bar. Gun metal, also known as red brass in the United States, is a type of bronze; an alloy of copper, tin and zinc. Proportions vary but 88% copper, 8–10% tin, and 2–4% zinc is an approximation. Originally used chiefly for making guns, it has largely been replaced by steel for that purpose. Gunmetal, which casts and machines well and is resistant to corrosion from steam and salt water,[1] is used to make steam and hydraulic castings, valves, gears, statues and various small objects, such as buttons. It has a tensile strength of 221 megapascals (32,100 psi) to 310 megapascals (45,000 psi), a specific gravity of 8.7, a Brinell hardness of 65 to 74, and a melting point of around 1,000 degrees Celsius. The Gunmetal Round Bars & Rods contain a high amount of copper, tin, and zinc. By changing the chemical compositions they classified in a variety of material grades like Gunmetal Alloy C90500, Gunmetal Alloy C90300, and Gunmetal Alloy C23000, etc What is the chemical composition of gunmetal Hollow Bar? Modern admiralty gunmetal is composed of 88 percent copper, 10 percent tin, and 2 percent zinc and is used for gears and bearings that are to be subjected to heavy loads and low speeds.Gunmetal rods, or gunmetal tubes, are commonly used in engineering, manufacturing, construction and household repair. They're hollow circular tubes made from gunmetal - a type of bronze which is an alloy of copper, lead, tin and zinc. They're different to bronze rods, in that they contain more zinc and less tin.
