Why do camera lens barrels use aluminum alloy?

Before we answer why do camera lens barrels use aluminum alloy material, let’s see what’t the raw material requirement of camera lens barrel:

1. The camera lens is a precise optical device. Since the lens needs to move relatively during the focusing and zooming process of the lens, in order to ensure the reliability of the movement, the lens barrel should be made of materials that are not easy to rust.

2. The camera lens is a precise optical device, and it should be ensured that the distance between the lenses is less affected by temperature changes. This requires the lens barrel to be made of a material with a low coefficient of thermal expansion.

3. The camera lens is a precise optical device, but it is inevitably subjected to vibration or shock, which requires the material of the lens barrel to have sufficient strength.

4. The camera lens should be easy to carry, and weight reduction should also be considered, which requires the lens barrel to be made of materials with low specific gravity.

Raw Material Feature of Aluminum Alloy 6061

The main alloying elements in 6061 aluminum alloy are magnesium and silicon, which have medium strength, good corrosion resistance, weldability, and good oxidation effect. It has excellent machining performance, excellent welding characteristics and electroplating properties, high toughness and no deformation after processing, dense material without defects and easy to polish; read the article [aluminum 6061] to check more information.

The reason why camera lens barrels use aluminum alloy 6061 due to the material can meet all the design function and surface requirements:

  1. high precesion
  2. high anti-corrosion
  3. high durability
  4. ligh-weight
  5. low cost for machining, especially for the parts need cnc machining.
