JDA1-已應(yīng)用在凱迪拉克CT6  

JDA1- HAS BEEN APPLIED IN CADILLAC CT66

JDA1是上海交通大學(xué)輕合金國家工程研究中心丁文江院士、彭立明教授帶隊歷經(jīng)6個月,自主研發(fā)的一款鋁硅系材料,于2015年3月一次性通過北美通用汽車的新材料量產(chǎn)審核,并正式納入北美通用材料清單,在凱迪拉克CT6中應(yīng)用。
 Jdal is an aluminum silicon series material independently developed by Ding Wenjiang, academician of Shanghai Jiaotong University light alloy National Engineering Research Center and Professor Peng Liming after six months. In March 2015,jdal
 passed the mass production audit of new materials of North American general motors, and was formallyinclude in the North American general material list, and was applied in Cadillac CT6.

高韌性延展佳

輕量化適用廣

高強(qiáng)度抗沖擊

JDA1壓鑄后無無需熱處理，常規(guī)壓鑄后4-72小時后即可達(dá)到德國S付6-T6材料熱處理后性能，減少大型薄壁件熱處理變形需矯正的要求。

JDA1保證抗拉強(qiáng)度的同時極大提升了延伸率。

JDA1適合車身結(jié)構(gòu)件（四門兩蓋/車身關(guān)鍵結(jié)構(gòu)件等）、底盤抗沖擊結(jié)構(gòu)件（電動化電池組托盤、發(fā)動機(jī)安裝支架等）。在保證強(qiáng)度的前提下，重量減輕26%，超出通用預(yù)定的20%的目標(biāo)。
