牌号:3A21
●特性及适用范围:
为Al-Mn系合金,是应用最广的一种防锈铝,强度不高(仅稍高于工业纯铝),不能热处理强化,故常采用冷加工方法来提高其力学性能;在退火状态下有高的塑性,在半冷作硬化时塑性尚好,冷作硬化时塑性低,耐蚀性好,焊接性良好,可切削性能不良。
●化学成份:

硅 Si :≤0.6
铜 Cu :≤0.20
镁 Mg:≤0.05
锌 Zn:≤0.10
锰 Mn:1.0~1.6
钛 Ti :≤0.15

注:单个:≤0.05;合计:≤0.10
●力学性能:
抗拉强度 σb (MPa):147~217
伸长率 δ10 (%):≤6
注 :压型板的坯料横向室温力学性能
试样尺寸:坯料厚度0.6~1.2
●热处理规范:
1)均匀化退火:加热510~520℃;保温4~6h;空冷。2)快速退火:加热350~410℃;随材料有效厚度不同,保温时间30~120min;空或水冷。3)高温退火:加热350~500℃;成品厚度≥6mm时,保温时间10~30min、<6mm时,热透为止;空冷。4)低温退火:加热250~300℃;保温时间为1~3h;空或水冷。
