Aluminium as a fabrication material

Posted 7:03 am, February 4, 2019 by Satish Garg / Category:

Aluminium has the capability of being extruded into complex shapes to exact tolerances. Aluminium can be formed into literally thousands of unique profiles, each one able to meet a number of specific structural and aesthetic requirements. It is this capability to provide simple elegant solutions to extremely complex design problems that has led to aluminium’s enduring appeal. Aluminium is chosen for outdoor use because it is a stable, corrosion-resistant and light weight metal. One of aluminium’s primary appeals to a specifier is its exceptional strength to weight ratio. At 2.7g/cm2, aluminium is 66% lighter than steel. It is also far less susceptible to brittle fractures. Indeed, when aluminium and steel structures are compared, aluminium’s greater modulus of elasticity means that weight ratios of 1:2 are easily attained. It can also be processed at high cutting speeds and welded connections are not necessary. These advantages help to reduce fabrication time. Constructions are realized with aluminium profiles extruded in the alloy EN AW 6060 according to EN 755-1. The mechanical characteristics conform to the standard EN 755-2, with a modulus of elasticity of 70GPa.
The tolerances are based on EN 755-3
