Aluminium alloy has superb processability and electrical conductivity, and it’s excellent heat radiating materials. 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. Because of its higher strength-to weight ratio, higher fuel efficiency, and better formability, as a result, in such a tough period regarding to energy and environmental issues, aluminium plays an essential role in weight lightening, and fuel efficiency increment to ease the energy and environmental problems. Its speicfication is from 10 to 900mm.
It’s widely used in electronics, airbus, aiviation, military, fuselage structurals, wing tension members, shear webs and ribs and structural fields where stiffness, fatigue performance and good strength are required.
