? T6510-固溶趁矾,通過拉伸控制量(設定0.5%~3%對軋管)消除應力+人工時效。拉伸后的產品不再矯直给僵。(solution heat-treated, stress-relieved by stretching a controlled amount (permanent set 0,5% to 3 % for drawn tube) and then artificially aged. The products receive no further straightening after stretching.)
? T6511-與T6510相同毫捣,除了在拉伸后允許輕微矯直以符合標準公差。(same as T6510 except that minor straightening is allowed after stretching to comply with standard tolerances)
