Description
Alloy V95pch 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; moulded panels of constant cross section with longitudinal fins in the aircraft industry, is made by a sweep of extruded finned tubes in the plane of the width of the fabric up to 2100 mm.
Note
Vysokoaromatichnyj alloy system Al-Zn-Mg.
