Product Introduction
Anodizing is an electrochemical process that forms an oxide layer on the surface of aluminum, providing enhanced corrosion resistance, hardness, and surface durability. Anodized aluminum is commonly used in power supply unit (PSU) enclosures, and aluminum alloys from the 1000 and 3000 series are often employed for their lightweight, durable, and thermally conductive properties.
The anodized surface offers electrical insulation and resistance to electromagnetic interference (EMI), ensuring the safety and proper functioning of the PSU. The hardness and strength of anodized aluminum protect the internal components, while its thermal dissipation properties help maintain optimal operating temperatures. Furthermore, the ability to customize the color and texture of the anodized surface adds to the visual appeal and personalization of the PSU enclosure.

Applications
Anodized aluminum stands out as a reliable and versatile material choice for PSU enclosures. It not only serves its functional purpose but also enhances the overall aesthetics and performance of the power supply unit.
1050, 1060, and 1100 aluminum alloys are pure aluminum alloys, which are commonly used choices for power supply unit (PSU) enclosures. They exhibit good electrical conductivity, workability, corrosion resistance and thermal conductivity, can be easily shaped, welded, and cut, making they suitable to house the internal components of the power supply, including the transformers, capacitors, circuit boards, and connectors.
