A7050-RAM2 aluminum aerospace alloy outperforms 7050

Elementum3D A7050-RAM2

A7050-RAM2, an aerospace and speciality Additive Manufacturing aluminium alloy from Elementum 3D, Erie, Colorado, USA, features a combination of high toughness and strength, as well as good stress corrosion cracking resistance.

Fatigue in metals and alloys can lead to the failure of a material at stresses well below the yield point of a material through a cyclic loading of the material in service. The fatigue life of a material is evaluated based on how many cycles it takes for a material to fail at a given stress below the yield strength of the material. To generate a full stress vs fatigue life/cycles curve (S-N curve), multiple dog-bone samples of the material are tested at a variety of stresses.
