牌号:2A14                                                                                                     ●特性及适用范围:                                                                                                    
2A14从成分看即属于硬铝合金又属于锻铝合金,与2A50相比,因含铜量较高,故强度较高,热强性较好,但在热态下的塑性不如2A50好,合金具有良好的可切削性,接触焊、点焊和滚焊性能良好,电弧焊和气焊性能差;可进行热处理强化,有挤压效应;耐蚀性不高,人工时效时有检间腐蚀倾向。
