Since the 1940's the majority of aircraft are manufactured in 2 basic aluminum alloys, 7075 and 2024 in a variety of alloys. Over the developing years additional alloys have been developed globally with slightly different mechanical properties and tempers like 2219 or 7050. Aircraft Extrusion Company stocks the majority of extruded shapes in the 7075 alloy. It is this alloy that is used in the structure of the aircraft.
Call our technical sales teams to discuss the availability and technical infomrtaion on 2000, 6000 and 7000 series extruded alloys.
Most designers are familiar with the physical characteristics of 2024 and 7075. Offering high strength, stiffness, fatigue durability, damage tolerance, low density to name just a few. Our technical sales team works with engineers and designers to find the best fit based on technical requirements and availability in the market place.
A question we get asked a lot is the availability of aircraft alloys. With a limited supply chain of aircraft grade extrusion mills it is a constant battle for smaller aircraft development companies to find new and improved alloys that can be purchased in timely and cost effective manner. Aircraft Extrusion Company has a network of suppliers, mills in distribution that with provide the most up to date information on existing and developing alloys.
7075 was introduced in the USA by Alcoa in 1943 and was standardized for aerospace use in 1945. Today it is still the most common aircraft alloy and is used in the airframe of both military and commercial aircraft.
The main alloying element in 2024 is copper. For applications that require high strength to weight ratio, as well as good fatigue resistance. Its most common application is the outer fuselage skin for both commercial and military aircraft.
A common alloy used in light aircraft. Magnesium and silicon are the main alloying elements. 6061 has great corrosion resistance, and while the mechanicals are much lower than 2024 and 7075 it is very formable and easily weldable.
The table below is to be used as a guide only. The properties shown have been copied from the federal QQ-A-200 specification.
