AEROSPACE ALUMINUM BARS

Liaocheng City Kuncheng Steel Pipe Co., Ltd. stocks aluminum bar for both aerospace and commercial applications. Since aluminum weighs approximately a third the weight of similar steel section, it is the obvious choice when weight is a factor.

Excellent resistance to corrosion permits its use without protection in most environments.  Aluminum’s ability to transmit heat rapidly and efficiently make it an ideal material for the heat transfer processes.    Aluminum bar can formed readily and has excellent weld ability.

Liaocheng City Kuncheng Steel Pipe Co., Ltd. stocks bars in 2024, 6061, 6063, 6101 and 7075 alloys in a variety of tempers.

Applications/markets:

• Aerospace
• Commercial Transportation
• Building & Construction
• Infrastructure
• Electrical
• Renewable Energy
• Mass Transportation Alloy Characteristics

  2024 ALUMINUM AEROSPACE BAR

  AL-2024 (UNSA902404) is an aerospace aluminum bar with cold finished or extruded aluminum wrought product providing high to moderate strength, very good machinability and weld ability with improved stress corrosion cracking resistance.

  2024 is known as the “aircraft alloy” in machining rod. It is one of the most popular alloys for cold heading and roll threading applications. It has high strength and excellent fatigue resistance. It is excellent on parts where good strength –to-weight ratio is needed. Machinability is good in heat treated and annealed condition. Commonly used in aircraft structural components, truck wheels, medical instruments, and screw machine products. We stock 2024-T351, 2024-T3511, and 2024-T4.
