高强度变形铝合金的新发展在于改进抗腐蚀性能,特别是要改进抗应力腐蚀和剥落腐蚀的性能。关于应力腐蚀要达到或超过T73状态,同时还不损失强度(T7状态显著地改善7000系合金的抗应力腐蚀性能,但屈服强度要比T6状态低15％)。较好的状态。T76状态是阿尔卡为7075和7178这两个合金发展的,具有高的抗剥落腐蚀 New developments in high-strength, deformed aluminum alloys have been to improve corrosion resistance and, in particular, to improve resistance to stress corrosion and flaking corrosion. Stress corrosion is about to reach or exceed T73 without loss of strength (T7 conditions significantly improve the stress corrosion resistance of 7000 series but yield strength is 15% lower than T6). Better state. T76 state is Alcatel 7075 and 7178 these two alloys developed with high anti-spalling corrosion
