　　熱強度高

　　使用溫度(du)(du)(du)比(bi)鋁(lv)合(he)金高(gao)幾百度(du)(du)(du)，在(zai)中等溫度(du)(du)(du)下(xia)(xia)仍(reng)能保持所要(yao)求的強(qiang)度(du)(du)(du),可(ke)在(zai)450～500℃的溫度(du)(du)(du)下(xia)(xia)長期工(gong)(gong)作這兩類(lei)鈦合(he)金在(zai)150℃～500℃范圍內仍(reng)有很高(gao)的比(bi)強(qiang)度(du)(du)(du)，而鋁(lv)合(he)金在(zai)150℃時(shi)比(bi)強(qiang)度(du)(du)(du)明顯下(xia)(xia)降(jiang)。鈦合(he)金的工(gong)(gong)作溫度(du)(du)(du)可(ke)達(da)500℃，鋁(lv)合(he)金則在(zai)200℃以下(xia)(xia)。

　　抗蝕性好

　　鈦(tai)合金在潮(chao)濕的大氣(qi)和海水(shui)介質中工作(zuo)，其抗蝕(shi)性(xing)遠優于不銹鋼;對點蝕(shi)、酸(suan)蝕(shi)、應力(li)(li)(li)腐蝕(shi)的抵(di)抗力(li)(li)(li)特別強(qiang);對堿(jian)、氯(lv)化(hua)物(wu)、氯(lv)的有機物(wu)品、硝酸(suan)、硫酸(suan)等有優良的抗腐蝕(shi)能力(li)(li)(li)。但(dan)鈦(tai)對具(ju)有還原(yuan)性(xing)氧及鉻(ge)鹽(yan)介質的抗蝕(shi)性(xing)差。

　　低溫性能好

　　鈦合金(jin)(jin)在低(di)溫(wen)和(he)超低(di)溫(wen)下，仍能保持其力學性能。低(di)溫(wen)性能好，間隙元素極低(di)的(de)(de)鈦合金(jin)(jin)，如TA7，在-253℃下還能保持一定的(de)(de)塑(su)性。因此，鈦合金(jin)(jin)也是(shi)一種重要的(de)(de)低(di)溫(wen)結(jie)構(gou)材料。
