HIGH SPECIFIC STRENGTH AL-LI SERIES ALLOY MATERIAL FOR VESSEL EXCELLENT IN CORROSION RESISTANCE

摘要

PURPOSE: To produce a high specific strength Al-Li series alloy material excellent in corrosion resistance by incorporating specified ratios of Li, Mg, Cu, Zr, Cr, Mn, V and Ti into Al. ;CONSTITUTION: A high specific strength Al-Li series alloy material for a vessel contg., by weight, 1.5 to 3.5% Li and 1.0 to 5.0% Mg and furthermore contg. one or ≥two kinds of elements selected from the group of 0.05 to 1.5% Cu, 0.05 to 0.3% Zr 0.05 to 0.3% Cr, 0.05 to 1.5% Mn, 0.05 to 0.3% V and 0.005 to 0.1% Ti, and the balance Al with inevitable impurities is produced. In this way, the alloy material excellent in corrosion resistance can be obtd., and the lightening and speed-up of a vessel can be attained.;COPYRIGHT: (C)1994,JPO&Japio
