Due to high specific strength and resistance to high temperatures, as well as resistance to vibration loads and low specific gravity, composite companies use carbon composites. The use of composite materials in the aerospace industry can reduce the weight of the final product and thereby reduce operating costs and fuel consumption. The materials used in the space industry are an alloy of aluminum with magnesium AMg6, aviation aluminum, stainless steel, titanium, invar - an alloy of nickel (36%), and iron. The latter alloy is also good in that it has a low coefficient of thermal expansion, which makes it possible to use it in precision instrumentation.
