Yunnan Copper Copper Industry (Shenzhen) Co., Ltd. brass wire: Material: H59, H59-1, H59-2, H59-3, H60, H60-2, H62, H63, H65, H68, H70, H80, H90; C1100 , C1020, C2680, C2800, C2600, C2801 brass cord material, semi-hard brass wire, brass screws, wire, precision cutting brass wire, special thick brass wire. Brass wire room, there are three organizations: the amount of 35% zinc brass, the microstructure at room temperature by the α single phase solid solution composition, called α brass; zinc content in the range of 36% -46% brass within the microstructure at room temperature by the (α + β) two-phase, known as the (α + β) brass (two-phase brass); zinc content of more than 46% to 50% of the brass, The microstructure at room temperature consists of only phase β, called β brass. (2) pressure processing performance α single-phase brass (from H96 to H65) with good ductility, can withstand hot and cold processing, but the α single-phase brass prone to temperature brittle forging and other thermal processing, the specific temperature range Zn containing different amounts vary, typically between 200 ~ 700 ℃. Thus, thermal processing temperature should be higher than 700 ℃. The main reason for the single-phase α brass in the temperature brittle zone in Cu-Zn alloy system α phase region and the existence of Cu3Zn Cu9Zn two ordered compounds, occurs when low-temperature heating and orderly transition of the alloy brittle; other alloy in the presence of trace amounts of lead, bismuth harmful impurities and copper forming low melting point eutectic films distributed in the grain boundary, resulting in intergranular fracture during thermal processing. Practice shows that adding small amounts of cerium can effectively eliminate temperature brittle .1) ordinary brass ordinary brass room organization is a binary alloy of copper and zinc, zinc content varies greatly, so the room is also very different organization. According Cu-Zn binary state diagram (Figure 6), brass room three organizations: the amount of 35% zinc brass, the microstructure at room temperature by the α single phase solid solution composition, called α Huang copper; zinc content in the range of 36% -46% of the brass, the microstructure at room temperature by the (α + β) two-phase, known as the (α + β) brass (two-phase brass); with zinc more than 46% to 50% of the brass, the microstructure at room temperature consists of only phase β, called β brass. (2) pressure processing performance α single-phase brass (from H96 to H65) with good ductility, can withstand hot and cold processing, but the α single-phase brass prone to temperature brittle forging and other thermal processing, the specific temperature range Zn containing different amounts vary, typically between 200 ~ 700 ℃. Thus, thermal processing temperature should be higher than 700 ℃. The main reason for the single-phase α brass in the temperature brittle zone in Cu-Zn alloy system α phase region and the existence of Cu3Zn Cu9Zn two ordered compounds, occurs when low-temperature heating and orderly transition of the alloy brittle; other alloy in the presence of trace amounts of lead, bismuth harmful impurities and copper forming low melting point eutectic films distributed in the grain boundary, resulting in intergranular fracture during thermal processing. Practice shows that adding small amounts of cerium can effectively eliminate temperature brittle. Extremely versatile material, such as water tanks with water supply and drainage, medals, bellows, serpentine tube condenser, shells and various forms of complex impulse products, hardware and other items. They could well withstand thermal processing, machinery and appliances used for various parts, stamping parts and musical instruments, etc..
