QCr0.5 |
在常温及较高温度下(400℃)具有较高的强度及硬度，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著提高;易于焊接和钎焊，在大气和淡水中具有良好的抗蚀性，高温抗氧气性好能很好在冷态和热态承压力加工;但其缺点是对缺口的敏感性较强，在缺口和尖角处造成应力集中，容易引起机械损伤，故不宜做整流子片。
Under normal tempe rature and high temperature (400℃),the alloy boasts high strength,high hardness,high electrical and heat conductivity,high wearability,and frictiorreduction,After age hardening.its strength.hardenss.electrical andheat conductivitywill be improved greatly;Liable to welding and brae weldingp;high corrosion resistanceunder atmosphere and fresh water,high resistance against oxidation under higltemperature:it can be processed under pressure in cold and hot status;the weak poinis that it is sensitive to gap.which leads to stress concentration at gap and sharp pointmechanical damage so it is not suitable to make commutator segment. |
制作工作温度350℃以下的电焊机电极、电机整流子片以及其他各种在高温下工作的.要求有高的强、硬度、导电性和耐磨性的零件，还可以双金属的形式用于刹车盘和圆盘。 Electrode of welder working under thetemperature lowerthan350℃, commutatoisegmentand other component working undeihigh temperature and requiring high strength,high hardenss and high electrical and heatconductivity.brake disk and round plate indouble-metal form | ||||||||

QCr0.5-0.2-0.1 |
加有少量镁、铝的铬青铜，与QCr0.5相比，不仅进一步提高耐热性和耐蚀性，而且可改善缺口敏感性，其他性能和QCr0.5S相似。
Add small quantity of magnesium and aluminum to chrome-bronze;compared withQCr0.5.the heat resistance and corrosion resistance of the alloy are increased;it is lesssensitive to gap and other performances are similar with those of QCr0.5. |
