Abstract

Results of comprehensive investigations of extruded panel from high-strength weldable aluminum-lithium alloy V-1469 with low density made at JSC KUMZ industrial-scale production are given in the article. Mechanical, corrosion, resource characteristics and weldability of extruded panel are investigated. The welded extruded panel from alloy V-1469 application in wing design of perspective products of aviation engineering will allow to reduce weight thanks to increased strength-to-weight ratio of alloy in comparison with serial alloy V95o.ch.-Т2 and also due to application of welded joints instead of bolt and rivet. The work is executed within implementation of the complex scientific direction 8.1. «High-strength welded aluminum and aluminum - lithium alloys of the lowered density with the increased fracture toughness» («The strategic directions of development of materials and technologies of their processing for the period till 2030») [1].
