ALUMINUM ENCLOSURES

Nemaco manufactures best quality aluminum enclosures per NEMA rating standards in many configurations choices of types such as wall mount, floor mount, free standing, SCADA and mobile wheel (portable) cabinets.

Aluminum is a silvery-white, light weight metal provides excellent corrosion resistance and excellent thermal heat conduction. It is soft and malleable. Therefore, it is used in a huge variety of products in various industry such as solar battery storage, telecommunication cabinets and network server rack cabinets.

We manufacture aluminum enclosures using two different type of aluminum alloys which is 5052 aluminum and 6061 aluminum to perform the best performance of enclosure. Generally, aluminum 6061 is stronger than 5052, but it is very difficult to bend (it will crack along the edge). Therefore, we use it for flat bar, extruded angle, interior plate, and grand plate. However, we can perform aluminum 6061 with wide bending radius. On the other hand, aluminum 5052 is softer, easier to bend to specific shapes. Therefore, we use it when bending as required to be formed to manufacture enclosures.

5052 & 6061 Aluminum Metal Properties

5052 Aluminum

  • High Strength
  • Lightweight
  • High corrosion resistance
  • Smooth surface
  • Best welding aluminum
  • High modulus of elasticity
  • Easy to form
  • Not heat treatable

6061 Aluminum

  • High Strength
  • Lightweight
  • Superior corrosion resistance
  • Semi-smooth surface
  • Hard to form
    • Can be bend with a wide radius
    • Good for flat bar, extruded angle, interior plate, and grand plate.
  • Heat treatable

First of all, we need to know how they categorized aluminum to each series. In the separation process, they consider to materials that are included in aluminum, such as iron, copper, magnesium, silicon zinc, and manganese. Including these materials in aluminum alloy will change and improve aluminum’s core characteristics. For example, adding magnesium will increase strength and improves their strain hardening ability. Aluminum 5052 and 6061 are both know as wrought alloys. Notably, they are different from the cast aluminum alloy.

In particular, each level of wrought alloys is denoted by four digits, 1xxx to 7xxx. Where with the first digit elucidates primary of materials or elements that are alloyed with aluminum.

Therefore, we show you each series below.

SeriesPrimary Alloying Element
1xxxAluminum – 99.00% or Greater
2xxxCopper
3xxxManganese
4xxxSilicon
5xxxMagnesium
6xxxMagnesium and Silicon
7xxxZinc
