摘　　要：铝青铜具有许多优良的性能,在机械行业中起着重要的作用。尤其含铝量约10%时机械强度最高,且能通过热处理进一步强化,故QAl9-4可得到较高的强度、硬度、耐磨性、冲击无火花等优良性能。该材料已在抽油井光杆密封装置和阀门上得到了广泛应用,结果表明,QAl9-4耐磨、耐腐蚀,且对光杆及其密封填料、阀杆等具有良好的保护作用,提高了产品的使用寿命。aluminum bronze has many excellent performances,plays an important role in the mechanical industry. Especially when the content of about 10% high mechanical strength,and can be further enhanced by heat treatment,so QA19-4 can obtain higher strength, hardness,wear resistance,excellent properties such as impact no spark. This material has been found in a wide range of applications, from pumping well polished rod sealing device and a valve,QAlg-4 wear-resistant,corrosion resistance, and has good protective effect on the polished rod and the sealing packing,valve stem,increase the service life of the product.
