80%的熱變形。②其冷沖壓性能與合金狀態(tài)有關(guān),退火（O）狀態(tài)的冷沖壓性能良好,H32、H34狀態(tài)時次之,而H36/H38狀態(tài)時不好。⑵焊接性能①該合金的氣焊、電弧焊、電阻焊、點(diǎn)焊、縫焊性能良好,二氬弧焊時出現(xiàn)結(jié)晶裂縫傾向。硬釬焊性能尚好,而軟釬焊性能較差。②焊縫的強(qiáng)度和塑性高,焊縫強(qiáng)度達(dá)基體金屬強(qiáng)度的90%~95%。但焊縫的氣密性不高,推薦用5A03合金作焊料,可提高其氣密性,并可消除裂縫傾向。⑶機(jī)械加工性能該合金退火狀態(tài)的切削加工性能不好,而冷作硬化狀態(tài)時有所改善。新手上路成長任務(wù)編輯入門編輯規(guī)則本人編輯我有疑問內(nèi)容質(zhì)疑在線客服官方貼吧意見反饋投訴建議舉報不良信息未通過詞條申訴投訴侵權(quán)信息封禁查詢與解封?2025?Baidu?使用百度前必讀?|?百科協(xié)議?|?隱私政策?|?百度百科合作平臺?|?京ICP證030173號?京公網(wǎng)安備11000002000001號window.PAGE_DATA=
