Dongguan Changan Hin Metal Materials Co., Ltd. in southern China set up earlier the larger a set of metal materials production, trade, processing, logistics and distribution as one integrated company. Phosphor bronze degassing agents with added phosphorus P content of 0.03 to 0.35% tin content of 5 to 8%., And other trace elements such as iron Fe, Zn Zn etc. ductility, fatigue resistance are good electrical and mechanical material can be used , reliability is higher than the general copper alloy products. The former refers to the copper-tin alloy bronze, brass, copper-nickel alloy after the addition of a copper alloy known as bronze, and often in front of the bronze name preceded by the name of the first major add elements. ﹑ Bronze casting performance minus good friction properties and good mechanical properties, suitable for the manufacture of bearings, worm gear, gear and so on. Aluminum bronze, high strength, wear resistance and corrosion resistance, high load for casting gear, bushings, marine propeller. Elastic limit of beryllium copper and phosphor bronze, good conductivity, suitable for the manufacture of precision springs and electrical contact element, beryllium copper used to make coal, oil depots and other non-sparking tools. Phosphor bronze with a higher corrosion resistance, abrasion resistance, impact spark does not occur. For medium-speed, heavy-duty bearings, maximum working temperature of 250 ℃. With self-aligning, insensitive to skew the bearing force uniform high capacity, at the same time by the radial load, self-lubricating no maintenance characteristics. Lintong is an alloy of copper, with good electrical properties, easy to heat, to ensure safety at the same time have a strong resistance to fatigue. Jack Reed hardwired electrical configuration of phosphor bronze, non-rivet connection or friction contacts can ensure good contact, good elasticity, pluggable stable. The alloy has good machinability and chip formation properties, can quickly short part time. Lintong alloy is widely used as an intermediate copper casting, solder and other fields, occupies an important place in the development of national economy. Chemical composition of copper Cu: balance tin Sn: 6.0 ~ 7.0 lead Pb: ≤0.02 Phosphorus P: 0.10 ~ 0.25 Al Al: ≤0.002 Iron Fe: ≤0.05 Si Si: ≤0.002 Antimony Sb: ≤0.002 Bi Bi: ≤0.002 Note : ≤0.1 (impurity) QSN6.5-0.1 mechanical properties Note: The vertical bars at room temperature tensile mechanical properties of the sample size: the diameter or on the side away from 5-12 Heat treatment thermal processing temperature 750 ~ 770 ℃;
