Modulus of elasticity (or also referred to as Young's modulus) is the ratio of stress to strain in elastic range of deformation. For typical metals, modulus of elasticity is in the range between 45 GPa (6.5 x 10 6 psi) to 407 GPa (59 x 10 6 psi). Modulus of elasticity is also a measure of material's stiffness or resistance to elastic ...

Recycling and market needs. We are often asked if we are able to indicate the amount of our aluminium which is recycled once or several times. This is not possible as a large part of our material comes from new production as the global market for aluminium is subject to high growth and where recycled aluminium / scrap is not enough to cover the actual demand.
