供应导热及耐磨性铬青铜【QCr0.5铬铜板】交货期多久? The company supplies: die steel, alloy steel, stainless steel, high speed steel, structural steel, carbon steel, tool steel, spring steel, gear steel, free cutting steel, no magnets, breathable steel, high-speed steel, tungsten steel, u steel wear-resisting, heat resistant steel painted graphite, aluminum, titanium alloy # beryllium copper, chromium high copper, lead brass, tin bronze, nickel, brass, nickel cupronickel, copper alloy, oxygen-free copper, phosphor bronze, aluminum bronze, aluminum, copper, tungsten copper, copper, brass, copper to end domestic and imported materials inventory welcome to inquire! QCr0.5铬青铜在常温及较高温度下、具有较高的强度和硬度,导电性和导热性好,耐磨性和减摩性也很好,经时效硬化处理后,强度、硬度导电性和导热性均显着提高;易于焊接和纤焊,在大气和淡水中具有良好的抗蚀性,高温抗氧化性好,能很好承受冷态和热态压力加工;但其缺点是对缺口敏感性较强,在缺口和尖角处造成应力集中,容易引起机械损伤,故不宜作整流子片。 QCr0.5 铬青铜化学成分: 铁 Fe:0.1 镍 Ni:0.05 Cu:余量 杂质:0.5 铬 Cr:0.4-1.1 QCr0.5 铬青铜力学性能:抗拉强度 (σb/MPa):≥390 伸长率 (δ10/%):≥5 注:棒材的力学性能 试样尺寸:直径或对边距离(5-40) 热处理工艺:热加工温度900~950℃;淬火温度950~1000℃水冷;l回火温度400~450℃。
