Aircraft Aluminum Specialists

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 information on 2000, 6000 and 7000 series extruded alloys.

Choosing the Right Aircraft Aluminum

7000

7075 Extrusion Alloy

Introduced by Alcoa in 1943 and standardized for aerospace use in 1945, 7075 remains the most common aircraft alloy today. Used extensively in airframes for both military and commercial aircraft, it offers exceptional strength-to-weight ratio.

High strength-to-weight ratio
Excellent fatigue resistance
Standard in military and commercial airframes

2000

2024 Extrusion Alloy

With copper as its main alloying element, 2024 delivers high strength-to-weight ratio and excellent fatigue resistance. Most commonly used for outer fuselage skin in both commercial and military aircraft.

Superior damage tolerance
High toughness properties
Ideal for structural components

6000

6061 Extrusion Alloy

A versatile alloy for light aircraft applications. With magnesium and silicon as the main alloying elements, 6061 provides outstanding corrosion resistance. While its mechanical properties are lower than 2024 and 7075, it offers superior formability and weldability.

Excellent corrosion resistance
Superior formability
Excellent weldability

Aircraft Aluminum Characteristics

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.

Aircraft Aluminum Availability

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.
