There is a very good ductility and high strength, good cutting performance, easy to weld, general corrosion is very stable, but prone to corrosion cracking. Ordinary brass varieties most widely used one. H68 (C2680) brass performance and H70 (C2600) is very similar, but there are cold, "quarter crack" tendency, used as a complex cold stamping and deep drawing parts, such as bellows, bullets artillery shells and other product specifications Spot Copperbelt - Thickness: 0.01-2.0mm, width: 4-600mm copper - Thickness: 0.2-100mm, width: 305-1000mm, length: 1200-2000mm copper - Diameter: 0.01-15.0mm brass - Thickness: 0.1-100mm, outer diameter: 1-600mm copper - Diameter: 1.0-200mm, Length: 2500-6000mm brass brass rods theoretical weight formula weight formula: Diameter (mm) x Diameter (mm) x0.028x length (m) yellow copper weight formula: length (m) x width (m) x thickness (mm) x8.5 brass band weight formula: length (m) x width (m) x thickness (mm) x8. 5 Brass weight formula: Diameter (mm) x Diameter (mm) x0.028x length (m) brass flat bar weight formula: length (m) x width (m) x thickness (mm) x8.5 Dongguan City OUYAO Alloy Products Limited Permanent mold large mayor Changan Wu Sha Li housing Sixth Avenue Industrial sales: 13356450448 Chen Shihai hotline: 0769-85305083 / (QQ: 3073581049)
