aluminum electrical enclosures
Aluminum enclosures are ideal for protecting sensitive electronic components in both indoor and outdoor environments. They offer inherent EMI/RFI shielding and are available in a range of sizes and styles, including waterproof models that meet NEMA 4X, 6, 6P, 12, 13 and IP67/IP68 standards. Commonly used in industries like transportation, manufacturing, and electrical, these enclosures are valued for their:
✓ Excellent corrosion resistance for long service life
✓ High impact resistance for industrial durability
✓ Effective heat dissipation for thermal management
✓ Lightweight and machinable design for easy handling and customization

Diecast Aluminum Enclosures
Diecast aluminum enclosures are specially designed protective housings used to safeguard sensitive electrical and electronic components. These enclosures are made through a diecasting process, where molten aluminum is injected into a mold to form a strong, lightweight, and durable casing. They are ideal for applications that require high durability, excellent corrosion resistance, and protection against physical impacts, dust, and moisture.
Effective Heat Dissipation: The material's excellent thermal conductivity allows for efficient heat dissipation, which is crucial for preventing overheating of sensitive electrical equipment.
EMI/RFI Shielding: Diecast aluminum enclosures are ideal for applications where electromagnetic interference (EMI) or radio-frequency interference (RFI) needs to be minimized, offering inherent shielding to protect electronic components.
Waterproof Options: Many diecast aluminum enclosures come with waterproof ratings like IP67 or IP68, making them suitable for environments exposed to rain, splashes, or temporary submersion.

We offer a wide range of aluminum enclosures, including:
Extruded Aluminum Enclosures – Ideal for lightweight, customizable housings with excellent heat dissipation.

FAQ
What is an aluminum electrical enclosure?
An aluminum electrical enclosure is a protective box made from aluminum, designed to house electrical or electronic components. It shields equipment from dust, moisture, and environmental damage, especially in industrial and outdoor settings.
What are the benefits of using aluminum enclosures?
✅ Lightweight – Easier to install and transport than steel.
✅ Corrosion-resistant – Ideal for outdoor or marine environments.
✅ Good heat dissipation – Aluminum conducts heat efficiently.
✅ EMI shielding – Provides natural protection against electromagnetic interference.
✅ Durable and strong – Withstands tough conditions while being easy to modify.
Are aluminum electrical enclosures waterproof?
Yes, many aluminum enclosures are rated IP65, IP66, or IP67, meaning they are dust-tight and resistant to water jets or temporary submersion. Always check the IP rating for your specific use case.
Where are aluminum enclosures commonly used?
Industrial control systems
Outdoor electrical panels
Renewable energy installations (solar, wind)
Marine environments
Telecommunications
Automation equipment
Can aluminum enclosures be customized?
Yes! Most manufacturers offer:
Custom cutouts for connectors and displays
Powder coating or anodizing
Engraving or silk-screen printing
Internal mounting options (DIN rails, brackets, etc.)
Are aluminum enclosures suitable for outdoor use?
Absolutely. With proper sealing and surface treatment (e.g., anodizing or powder coating), aluminum enclosures perform well in harsh outdoor environments.
Do aluminum enclosures require grounding?
Yes, aluminum is conductive. Proper grounding ensures electrical safety and helps with electromagnetic shielding.
What IP rating should I look for?
IP54 – Dust and light splashes
IP65 – Dust-tight and water-resistant
IP67 – Dust-tight and submersible up to 1 meter for 30 minutes
Choose based on exposure to rain, dust, or immersion.
