Aluminum plate for aviation application

2021-01-14 11:42:36

Aluminum and its alloys are today considered one of the most practical of metals for a variety of reasons. Its low cost, light-weight, and modern appearance are among the primary reasons for its widespread use. It is non-sparking, electrically conductive, thermally conductive, non-magnetic, reflective, and chemically resistant. It is popular in the construction, marine and aircraft industries because of its ease of fabrication, non-toxicity, strength (pound-for pound), and resistance to the corrosive atmospheres of industry and marine environments. Anodizing increases this corrosion resistance and also permits iridescent finishes in different colors. Some alloys are slightly corrosive and so are cladded with a thin layer of aluminum for added protection.

 Aluminum plate is an important structural material for aircraft, and it is mainly used in fuselage, wing skin, oil tank etc. By using aluminum composite materials, the density of aircraft’s outer skin can be decreased by 5%-7%. As a result, the total weight can be reduced 10%, and therefore fuel efficiency increases. Moreover, 7% can be increased in stiffness of the material by using aluminum plate. Due to the superb corrosion resistance, fatigue resistance and damage tolerance of alunimium alloy, the inspection period can be extended and hence decreasing maintenance cost.
