主要特性 Main features |
|
QAL5 |
为不含其它元素的铝青铜，有较高的强度、弹性和耐磨性，在大气、淡水、海水和某些酸中耐蚀性高，可电焊、气焊、不易钎焊，能很好地在冷态或热态下承受压力加工，不能火回火强化。 Aluminum-bronze containing no other chemical element boasts high strength,high elasticityand high wearability.high corrosion resistance under atmosphere,fresh water,seawater andsome acids;it is suitable for electric and gas welding,not suitable for braze welding;i.can be processed under pressure in cold and hot status;it is not suitable for quenching |
|
QAL7 |
性能用途和QAL5相似，因含铝量较高，其强度较高 lts performance and use are similar with those of QA15;its content of aluminum is high soits strength is high |
|
QAL9-2 |
含锰的铝青铜，具有较高的强度，在大气、淡水和海水中抗蚀性很好，可以电和气焊，不易好群。在势态和冷态下压力加工性均好Aluminum-bronze containing manganese features high strength,high corrosion res stamceunder atmosphere,fresh water and seawater;it is suitable for electric and gas welcimgmcsuitable for braze welding;high machinability uner pressure in hot and colod status. |
|
QAL9-4 |
含铁的铝青铜，有高的强度和减摩性，良好的耐蚀性，热态下压力加工性良好。可电样和气样。但舒辉性不好，可用作高锡耐磨青铜的代用.
Aluminum-bronze containing Fe features high strength,friction reducmiom prooerty hicrcorrosion resistance.easily-processed under pressure in hot status it is suitable forelectric and gas welding.not suitable for braze welding:it can wsed as substitute ofhigh tin conten tanti-wear bronze |
