2014 O T4 T6 T351 Aerospace Aluminum Sheet Plate

What is 2014 grade aluminium?

2014 aluminum plate is a high-strength, precipitation-hardened alloy belonging to the 2000 series aluminum alloys. It is renowned for its excellent machining characteristics and high-temperature performance, making it widely used in industries where strength and durability are crucial, particularly in aerospace, military, and automotive applications.

Due to the relatively poor corrosion resistance of 2014 aluminum, this alloy is often provided in a clad form (surface covered with pure aluminum) or undergoes surface treatments (such as painting) to prevent corrosion.

2014 aluminum alloy (2014A) contains 3.9% to 5% copper, offering excellent strength and good machinability. Due to its high strength, 2014 aluminum alloy is widely used in aircraft structures, military vehicles, bridges, weapons manufacturing, and other structural components requiring high strength and hardness.

2014 aluminum plate is the second most popular alloy in this series and is mainly processed through extrusion and forging techniques. This alloy also has good machinability, making it suitable for manufacturing molds, heavy machinery parts, wheels, truck frames, and suspension system components. The standard specifications for 2014 aluminum alloy include ASTM B209 and UNS A92014.

Although 2014 aluminum alloy has good machinability, its cold formability and weldability are relatively poor after full heat treatment.

Characteristics of 2014 Aerospace Aluminum Plate

• High strength-to-weight ratio: 2014 aluminum is ideal for aerospace/structural applications.
• Heat treatable: Can be strengthened through T6 (solution heat treatment + artificial aging) or T651 (stress relief).
• Weldability: Poor; prone to cracking (use TIG/MIG with filler 4043/4145).
• Sensitivity: Prone to stress corrosion cracking in thick sections; avoid unprotected use in marine environments.
• High mechanical strength: 2014 aluminum alloy possesses excellent strength properties, maintaining stable performance under high loads. It is widely used in aircraft structural parts and fuselage frames, where high tensile and yield strength are required to meet stringent engineering demands.
• Excellent fatigue resistance: 2014 alloy has good fatigue performance, capable of withstanding prolonged cyclic loads without fatigue failure. This characteristic is crucial for aircraft, which endure repeated stress during flight, helping extend the service life of structural components.
• Superior machinability: 2014 aluminum alloy exhibits good performance during machining and can be effectively shaped using common machining methods such as cutting, milling, and welding. This makes it efficient for manufacturing complex shapes and precision components while ensuring excellent surface quality.
• Requires protective coating to prevent corrosion: While 2014 aluminum alloy has high strength and good machinability, its corrosion resistance is relatively poor. In humid environments or corrosive media, aluminum alloys are prone to oxidation and corrosion. Therefore, it is usually necessary to apply protective coatings (such as anodizing, spraying, or painting) to enhance its corrosion resistance, ensuring reliability and durability in harsh environments.
