5083是高鎂鋁合金，強(qiáng)度較高，耐蝕性、可切削性良好，電弧焊性能良好。該合金廣泛用于船舶、汽車、飛機(jī)焊接件、地鐵、輕軌、制冷裝置、電視塔、鉆探設(shè)備、導(dǎo)彈零件、裝甲以及需嚴(yán)格防火的壓力容器等領(lǐng)域。但是由于該合金的合金化程度高、結(jié)晶溫度范圍寬，在鑄造過程中具有較大的熱裂紋傾向，而大規(guī)格(厚度630mm)的扁錠因整體應(yīng)力較大，在鑄造過程中的裂紋傾向更大，導(dǎo)致成品率低，生產(chǎn)難度較大。橋頭鋁電公司領(lǐng)導(dǎo)對(duì)此高度重視，全程參與、跟蹤、指導(dǎo)了整個(gè)試制過程。熔鑄分公司根據(jù)5083技術(shù)協(xié)議進(jìn)行了認(rèn)真的討論、研究，借鑒了其他公司的成熟經(jīng)驗(yàn)，確定工藝參數(shù)、制定試制方案，并組織人員進(jìn)行試制。
此次5083合金扁錠的試制成功，是橋頭鋁電公司熔鑄分公司在5系合金生產(chǎn)上取得的重大突破，為拓寬5系合金生產(chǎn)起到了十分重要作用，使公司產(chǎn)品轉(zhuǎn)型戰(zhàn)略向前推進(jìn)一大步。
