摘　　要：由于南山轻合金公司与天津忠旺铝业有限公司的投产,渤海湾已成为中国航空航天铝合金厚板生产基地,有世界稀少的7×××系铝合金T77状态长达39m的时效炉,并已进入批量生产阶段。再过三五年,该地区可成为世界三大航空级铝厚板供应基地之一。2017年,渤海湾有5个企业可以生产铝合金厚板,总生产能力210kt/a,但能够生产航空级铝合金厚板的只有3个企业。Due to going into production of Nanshan Light Alloy Co.,Ltd. and Tianjin Zhongwang Aluminum Co.,Ltd.,Bohai Bay region region has become the production base of aluminum thick plates for China's aerospace industry. Bohai Bay has a 39 m aging furnace for 7 ××× T77 aluminum alloys,which is rare around the world. This furnace has entered the stage of mass production. In another three to five years,the region could become one of the world's three largest bases supplying aviation-graded aluminum thick plates. In 2017, there were 5 enterprises in Bohai Bay that could produce aluminum alloy thick plates,with a total production capacity of 210 kt /a,but only 3 enterprises could produce aviation-graded aluminum thick plates.
