Aluminium Washers – Pressed Parts

Aluminium Washers – Pressed Parts

Aluminium washers are another type of essential component used in various applications. Aluminium washers are used to distribute the load of a threaded fastener and create a seal. Aluminium is chosen as the material for these washers due to its lightweight, corrosion resistance, and good mechanical properties.

Pressed parts or pressed components are manufactured through the metal stamping or pressing process. In the case of Aluminium washers, a sheet of Aluminium is placed between a die and a punch. The punch applies force to the Aluminium sheet, shaping it into the desired washer form.

Advantages of using Aluminium washers made from pressed components include:

  1. Lightweight: Aluminum is a lightweight metal, making these washers suitable for applications where weight reduction is important, such as in aerospace and automotive industries.
  2. Corrosion resistance: Aluminum naturally forms a protective oxide layer, providing corrosion resistance, particularly in non-aggressive environments.
  3. Good mechanical properties: Aluminum washers offer good strength and formability, allowing them to withstand various loads and pressures in different applications.
  4. Electrical conductivity: While not as conductive as Copper, Aluminium still possesses reasonable electrical conductivity, making it suitable for certain electrical applications.

Aluminum washers find applications in a wide range of industries, including aerospace, automotive, electronics, construction, and consumer goods.

As with other types of washers, selecting the appropriate size, thickness, and specifications of Aluminium washers is essential for their optimal performance and reliability in the intended application. Different applications may require specific considerations, such as the potential for galvanic corrosion when using Aluminium washers with dissimilar metals. Proper material selection and design are vital to ensure the best performance of Aluminium washers in the given context.
