Some Aerospace Applications of 7075 (B95) Aluminium Alloy

Abstract

Nowadays, aluminium alloys are of growing interest to scientists and are widely used in aerospace and allied industries due to their inherent lightness, high strength to weight ratio, excellent thermal and electrical conductance, good reflectivity and low working cost. Among the conventional structural materials used in aerospace applications aluminium alloys are frontrunners. This is due to the ability of modern aluminium alloys to achieve unique combination of properties, through alloying and heat treatment, tailored to particular applications. Aluminum alloy 7075 (B95) is a high-strength alloy that works in extreme conditions and is used in modern construction of aircraft, spacecraft and satellites. In this mini-review, we will briefly focus on some of the existing and growing applications of some 7xxx aluminum alloys, in particular 7075 (B95), in the aerospace industry. Possible options for continuing work in this area are considered, and some Bulgarian developments are presented.
