Product Description
Brass bars are rods made of an alloy of copper and zinc. They get their name from their yellow color.Copper content of 56%~68% of brass, its melting point of 934~967 degrees.The mechanical and wear resistance of brass are very good, can be used in the manufacture of precision instruments, ship parts, gun casings and so on.
Different amounts of zinc can have different colors, such as red and yellow for zinc content of 18%-20%, and brown-yellow for zinc content of 20%-30%.In addition, brass sounds unique, so the eastern gongs, cymbals, bells, horns and other instruments, as well as western brass instruments are made of brass.
Copper Round Bar, is widely known for its electrical applications whereas it has very high electrical and thermal conductivity. In addition, copper round bars are used in artistic works along with architectural applications because of its corrosion resistance and familiar green patina appearance acheived after being exposed to the elements. Copper rounds have excellent hot or cold workability and is very ductile when heated.
