据美国铝业公司技术报告称,位于匹兹堡附近的美国铝业公司实验室铸造的商品规格的2090铝锂合金扁锭,即将由印第安纳州拉裴特市美国铝业公司所属挤压管材厂加工成大型挤压件,还将由洛杉矶弗农(Vernon)厂加工成锻件。 127毫米厚的铝锂合金厚板和挤压件已交付海军倡导的试验与评价计划的29位成员。1.27厘米厚板系由美国铝业公司所属达汶波特(Davenport)厂轧制,其物理及化学性能达到铝锂合金研究计划所规定的目标。
According to Alcoa’s Technical Report, a commercial grade 2090 aluminum lithium alloy ingot cast at the Alcoa Laboratory near Pittsburgh is about to be machined by Extrusion Pipe Works owned by Alcoa in Lapping, Indiana Large extrusions will also be processed into forgings by the Vernon plant in Los Angeles. 127 mm thick aluminum lithium alloy plates and extrusions have been delivered to 29 members of the Navy’s pilot and evaluation program. The 1.27 cm thick slab is rolled by Davenport plant owned by Alcoa and has the physical and chemical properties that meet the targets set forth in the Al-Li alloy research program.
