prominent advantages of extruded aluminum tubes in automotive industry application scenarios（二）

2、 Typical application scenarios

1. Aircraft structural components

Airframe frame and truss:

Squeezed aluminum tubes are used for the longitudinal beams and transverse frames of the fuselage, supporting the skin and transmitting loads (such as the Boeing 787, which uses 6061-T6 aluminum tubes for some structures).

Landing gear hydraulic pipeline:

High strength 7075 aluminum tube replaces stainless steel, reducing weight by more than 30%, while withstanding high pressure (20-30 MPa) and vibration.

2. Aircraft engine system

Fuel and oil pipelines:

The extruded aluminum tube is resistant to fuel corrosion and can be further improved in sealing by anodizing the inner wall.

Heat exchanger piping:

Utilizing the high thermal conductivity of aluminum (237W/m · K) to manufacture cooling pipelines for engine radiators.

3. Spacecraft and Rockets

Fuel tank pressurization pipeline:

Aluminum tube lightweight design reduces rocket dead weight and enhances payload capacity (such as SpaceX rocket fuel delivery system).

Satellite structural support:

Using high-strength aluminum tubes (such as 7050-T7451) to support solar panels, adapting to space radiation and temperature differences.

4. Drones and Missiles

Body frame:

Squeezing aluminum tubes as lightweight main load-bearing structures enhances the endurance of unmanned aerial vehicles (such as the MQ-9 "Reaper" drone).

Missile shell:

Thin walled aluminum tubes achieve high stiffness and low weight, optimizing flight speed and range.
