Alloy 1430
Designation
Description
Alloy 1430 is used: for the manufacture of semi-finished products and parts of the power elements of the aircraft.
Note
The alloy system Al-Mg-Li-Cu. The alloy is recommended as a substitute for alloys D16. The alloy has a lower (~8%) density, increased (10%) modulus of elasticity and a high fracture toughness. 1430 alloy different from the alloy of 1440 high (1.5−2 times) and ductility slightly inferior to him the characteristics of low cycle fatigue.
Standards
Chemical composition
Al is the base.
OST 1 90048-90 hydrogen content of not more than 0.3 cm 3 / 100g metal. Mass fraction of each other impurity (not regulated) ≤ 0.05%, total mass fraction of other impurities ≤ 0.10%. Beryllium is not determined by chemical analysis, but is introduced by calculation.
