Description
Alloy B95 is used: for the manufacture of rolled and extruded lengthy (30 m) semi-finished panels for the top wing (plates, sheets), stringers (bent and pressed sheet), beams, columns and other elements of the fuselage and wings of modern aircraft (TU-204, Il-96, be-200) and other highly loaded structures, working primarily in compression; profiles with cross-sectional area of 200 cm2 and a diameter of circumcircle up to 350mm, designed for use in the aviation industry and special machine building industries; extruded large pipes.
Note
High strength alloy system Al-Zn-Mg.
