Aluminum Lead Screws for Compact and Non-Magnetic Uses

Businesses will be happy to learn that there are solutions available to help them keep up with the pace of lightweight design, which has emerged as one of the key future technologies in the domains of aircraft, automotive, and mechanical engineering.

After steel, aluminum is the most common metallic material. It is highly lightweight because, among other things, it has a very low density. In the presence of air, plain aluminum develops an oxide coating on its surface that prevents corrosion.

As a result of its self-passivation, the lightweight, stable combination, superior machinability, and non-magnetic nature of aluminum, more and more new application domains are becoming increasingly important.

Screws made of aluminum that are lightweight and non-magnetic

Aluminum lead screws are the best option for lightweight or non-magnetic applications in the healthcare, aerospace, and transportation industries.

Lead screws are frequently made from a variety of materials. In addition to alloy and stainless steel, aluminum is also a viable option. When the overall weight of the assembly or machine is important, aluminum lead screws are frequently used.

In the medical, aerospace, and transportation industries, aluminum lead screws are frequently used aslightweight, non-magnetic solutions. These applications, as examples, include:

· Aircraft seat motors

· The transportation sector's door-opening systems for buses and trains

· Drones' flight surfaces in the aerospace sector

Aluminum screws can be coated with Teflon/PTFE or anodized with Teflon and are produced with the same level of perfection as alloy and stainless-steel lead screws.

Aluminum Lead Screws Used in the Medical Sector

In equipment that uses magnetic fields, such as MRI machines, aluminum lead screws are ideal. In the MRI machine, patient beds have aluminum lead screws that are used to raise and lower the surface and move the patient into and out of the apparatus.

To account for the magnetic environment, aluminum lead screws are paired with nuts made of high-performance peek or a combination of acetals.

Aluminum Lead Screws Used in Aerospace Industry

There are several uses for aluminum lead screws in the aerospace sector. Airline seat actuators and drone flight surface control are two examples. Aluminum lead screws were used in the redesign of airline seat actuators to significantly reduce weight and expense while greatly improving customer comfort.

Also essential for controlling drone flying surfaces are aluminum lead screws. Additionally, drone onboard flight control and launching systems employ aluminum lead screws. Aluminum lead screws and unique hollow lead screws enable light control and positioning.

Aluminum Lead Screws Used in the Transportation Sector

Aluminum lead screws are frequently used in bus and train door-opening systems in the transportation sector. Doors can open and close with speed, accuracy, and safety thanks to door-opening systems.

The lightweight system may run with less maintenance and more efficiency thanks to dual lead screws made of aluminum that have both left- and right-hand threads.

In lightweight or non-magnetic applications, aluminum lead screws are the perfect choice in the medical, aerospace, and transportation industries.


Applications will continue to seek lighter, more affordable linear motion devices as these industries' technology develops. You can get assistance from the creative engineering staff at Wanfu Group in choosing the best components and
