Why Aluminum Enclosures Are Perfect For Electronic Equipments?


Aluminum is an excellent choice for many industries, with many applications. It’s known for being both light and flexible, making it a popular choice. Furthermore, the extrusion method can facilitate the creation of even more complicated shapes because of its high degree of adaptability. The tensile strength of pure aluminium for commercial application is 90MPa.

All electrical and electronic applications can benefit from aluminium enclosures, including amplifier housings and telecom storage, control systems, and automobile boxes. Electronics may be safely housed in aluminium enclosures. Metals such as aluminium are naturally EMI shielded because of their excellent heat tolerance and resistance to corrosion. In terms of aluminium enclosures, diecast and extruded models are both options. There is a wide range of NEMA and IP ratings to choose from. Thanks to a wide range of sizes and designs, locating the correct aluminium box or enclosure for indoor or outdoor applications is easy.

  • High Temperature Resistant
  • Durability: high impact, high tensile strength, rigidity
  • Rust and corrosion resistant
  • Lightweight, as compared to steel
  • Blocks passage of radio waves (naturally RFI shielded) and reflects externally generated interference, such as electromagnetic wavelengths
  • Built In Protection against fire and UV rays
  • Easy to paint and coat
  • It does not bulge or distort, and it is very beneficial at keeping away water, dust, and moisture
  • Scrap is a valuable and infinitely recyclable resource that reduces energy use and greenhouse gas emissions

Aluminium is lighter than steel and can be shipped at a lower cost, preferred over other metals. Due to a naturally occurring protective coating, it is also corrosion-resistant. Additionally, this coating can be enhanced by painting, anodizing, or die casting.

High thermal conductivity makes it ideal for dispersing heat. Even at a thickness of just a few millimeters, the metal foil is impenetrable. Heat can be transferred from the circuit board’s components to the outside, reducing internal temperatures and decreasing the risk of damage to the components from overheating. It is almost entirely unaffected over a wide range of temperatures, from -80 C to +150 C. Aluminum’s light reflectivity is above 80%, making it an excellent heat reflector under direct sunshine.

Generally, most people believe that aluminum can’t be recycled since it loses all of its qualities when recycled. Customizable enclosures are easier to work with than cases made of different materials. You can’t smell or taste it; it doesn’t absorb anything; it’s non-sparking, non-magnetic, and doesn’t catch fire.


In most cases, an enclosure consists of a mainframe with two or four-unit racks and mounting rails that is tall and rectangular in design. Some enclosures have back and front doors, side panels, top panels, and bases, depending on the design. Companies can customize various rack components or sections to match a customer’s demands or the environment. Enclosures are incredibly configurable. An extra-large file cabinet may easily be mistaken for one outside a data center or other industrial setting.

Many people confuse a cabinet with a rack; however, racks are merely the frame inside the cabinet used to hold and secure all electrical components. Cabinets protect a rack by enclosing it, providing all electrical input, electric cooling fans, and blocking radio frequency interference.

It is common practice to measure cabinets by their external dimensions, whereas racks are measured from the most forward point of the front rail to the rear-most end. Cable management, ventilation, and essential servicing access to components necessitate at least 6 inches of space between components and the back cabinet door.

EIA 310D standards specify rack widths. When using racks, one must consider the vertical spacing of all the equipment you wish to put in your enclosure. There are three mounting holes placed at 0.62, 0.62, and 0.50 inches apart in an EIA-compliant rack unit (RU) that measures 1.75 inches.


The aluminium rack mount enclosures are ideal for long-term storage since they shield the contents from the environment for a few years. For further protection, they are corrosion resistant. Whether heavy-duty or not, Aluminum mailboxes are superb at their job, and there is little room for error. Because they can withstand a sudden impact and are an excellent choice for shipping fragile items, water, dust, and dampness may all be kept at bay. Aluminum boxes are ideal for storing electrical components because they shield radio frequencies and Electromagnetic inductance from radio waves. However, to ensure this is done, there should be aluminium die casting so that the conductivity may work to your benefit.

Aluminum may be the ideal material if you’re seeking a sturdy box. Corrosive resistance, reflectivity, and recyclability are just some of the properties that make this metal ideal for so many uses.

· Electronics

Aluminum enclosures are commonly used to safeguard electrical components. Electronic devices, such as computers and servers, can be stored in these boxes.

Electronics gain significantly from the use of these enclosures. Second, they have a high rate of heat transference. As a result, it helps keep your electronics cool and protects them from overheating. They also protect from EMF/RFI. It aids in the reduction of electromagnetic and radio frequency interference.

In addition to their portability and lightweight, these boxes are impervious to harm in transit.

· Measuring Instruments

Measurement devices are commonly protected in aluminium boxes. A weather-resistant housing protects the device from the elements.

Consider the instrument’s size and weight while selecting an aluminium box for this purpose. A well-ventilated enclosure is essential to prevent overheating of the instrument. Storage of sensitive instruments such as thermometers necessitates shock-absorbent boxes, such as those lined with foam cushioning.

An additional factor to consider is the means of accessing the instrument. A box with a hinged cover is ideal if you frequently need to open it to obtain readings.

Finally, make sure the package is labeled correctly so that the contents can be immediately identified. To avoid damage or loss, the instrument must include a latch or clasp that can be firmly fastened.

· Network Devices

The heat dissipation properties of aluminium mean that network gears like routers and switches are frequently housed in aluminium boxes.

As a heat conductor and a low-weight metal, aluminium is excellent for electrical equipment casings.


  • Thermal conductivity: Check the thermal conductivity rating of the aluminium enclosure you’re considering for your electrical equipment. When it comes to heat transfer, aluminium has a thermal conductivity of 237 W/mK. As a result, it’s a good heat conductor and can assist in cooling down your electronic gadgets. Aluminum’s heat conductivity, on the other hand, might differ depending on the alloy.
  • Electrical conductivity:The electrical conductivity of aluminium is exceptional. Therefore, alternative materials like copper cannot be employed since they are too costly or impractical in electrical applications.
  • Magnetic permeability: Aluminium is impermeable to magnetic lines of force, so it is ideal for electrical shielding applications.
  • Environmental friendliness:Consider the environmental impact of your packing. Unlike other materials, aluminium may be recycled infinitely without deterioration in quality.
