Aluminum Enclosures

Aluminum enclosures are highly sought after in various industries due to their durability and resistance to corrosion. These enclosures, often used for electrical and instrument enclosures, offer protection to the components housed within. The material aluminum is inherently resistant to certain environmental factors, making it an ideal choice for such purposes.
Manufacturing of aluminum electrical enclosures is typically done with precision to ensure a tight fit and appropriate protection for the housed components. Some aluminum enclosure models come with specific IP (Ingress Protection) ratings, indicating their level of protection against elements like dust and water. This makes them suitable for a wide range of applications, from simple cases to more complex wall mount units.
The inherent characteristics of aluminum, such as its lightweight nature combined with its strength, make it a popular choice for instrument enclosures. This ensures that the sensitive equipment inside remains shielded from external damages. While there are various features available depending on the specific need or application, aluminum enclosures remain a reliable choice for many industries.

More Information about Aluminum Enclosures
Extruded Aluminum Enclosures
Extruded aluminum enclosures are a type of aluminum enclosure that is created using a specialized manufacturing process called extrusion. Extrusion involves forcing molten aluminum through a die to create a specific shape or profile. Extruded aluminum enclosures can also be machined and finished with various coatings and treatments to enhance their performance and make them extremely durable.
Aluminum Sheet Metal Enclosures
Aluminum sheet metal enclosures are a type of enclosure made from flat sheets of aluminum that are formed and welded together to create a box-like structure. Sheet metal enclosures are commonly used as instrument enclosures in a range of industrial and electronic applications, including telecommunications, electronics, and control systems.
FAQs
Is an aluminum enclosure available as a free standing unit or wall mount boxes?
Aluminum metal enclosures are available as free standing units as well as wall mount boxes.
NEMA 3R, 4, 4X Enclosures
Electrical enclosures are cabinets that are designed to house electrical components. Their main function is to protect the components, as well as to protect the operators from electrical hazards. Enclosures are typically made of solid plastics, fiberglass and metal materials, such as carbon steel, stainless steel and aluminum.
One of the most important things to consider when selecting an electrical enclosure is the NEMA rating. NEMA stands for National Electrical Manufacturer Association. They have developed a rating system which determines the types of environments an electrical enclosure can be used in.
NEMA 3R Enclosures
The NEMA definition of a 3R enclosure is as follows: ‘Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against access to hazardous parts, to provide a degree of protection of the equipment inside the enclosure against Ingress of solid foreign objects such as falling dirt, to provide a degree of protection with respect to harmful effects on the equipment due to the Ingress of water, rain, sleet or snow, and that will be undamaged by the external formation of ice on the enclosure.' NEMA 3R enclosures provide adequate outdoor protection while providing significant cost savings over NEMA 4 and NEMA 4X enclosures.
NEMA 4 Enclosures
They provide all of the same protections found in the NEMA 3R enclosures with two additional protection elements, protection against wind-blown dust particles and protection against hose directed water. NEMA 4 enclosures provide this additional protection using a gasket material to prevent water or dust from entering the enclosure, while the NEMA 3R enclosures rely on enclosure design and gravity to assist in diverting water and dust.
NEMA 4X Enclosures
They provide all of the same protections found in the NEMA 4 enclosures with one added protection element, corrosion resistance. NEMA 4X enclosures are typically made of either stainless steel or fiberglass.
