D1T (Д1Т)
D1T Aluminium Alloy: Premium Material for Aerospace Components
D1T aluminium is a high-performance material widely used in aerospace and precision engineering applications. It is renowned for its lightweight, high strength, and excellent machinability properties, making it a preferred choice for aircraft skins, frames, and other critical structural parts. Russian Metals offers D1T aluminium plates, sheets, and bars that meet the highest standards for aerospace components.
D1T aluminium is primarily alloyed with copper, and in some cases, small amounts of other elements such as manganese and magnesium are used to enhance its overall properties. The alloy’s high strength-to-weight ratio makes it particularly valuable in applications where reducing weight without sacrificing strength is critical, such as in aerospace and automotive industries.
