Description
The V-1469 alloy is usedfor producing all kinds of semi-finished products, including sheets cold rolled rolling. Mastered industrial production of plates with thickness of 1.2−6.0 mm and extruded profiles. Recommended for elements, working in compression, long in universal climatic conditions up to temperatures of 150 °C (upper surface of the wing, spars, beams, stringers). Effective use in aviation and rocket-space technique reduces the mass of parts and assemblies 10% in riveted and 20% in welded structures.
Note
High-strength weldable corrosion-resistant alloy of low density. Tech in the casting and processing pressure.
