When choosing the right cable gland for industrial or commercial applications, the differences between Aluminium and Brass Cable Glands are very important. These two materials are widely used for cable glands because of their properties, but each has different advantages depending on the application.This blog will break down the differences between Aluminium and Brass Cable Glands for you to make an informed decision for your project.
What Are Cable Glands?
Cable glands are mechanical fittings used to provide secure attachment and sealing of electrical cables ends to equipment. They keep the cables away from dust, moisture, and vibration, thereby providing safety and durability. The material for the cable gland, be it Aluminium or brass, plays a vital role in its performance.
Main Differences Between Aluminium and Brass Cable Glands
1. Material Composition
- Aluminium Cable Glands: These are light-weight Aluminium alloys, corrosion-resistant in specific environments.
- Brass Cable Glands: These are Brass Cable Glands, which are made of copper and zinc alloys, and they are resistant to wear and tear.
2. Corrosion Resistance
- Aluminium Cable Glands: They perform well in non-corrosive environments, but in highly corrosive areas, they require a coating for protection.
- Brass Cable Glands: Resistant to corrosion by themselves, especially in harsh industrial environments, and thus perfectly suited for marine and outdoor applications.
3. Electrical Conductivity
- Aluminium Cable Glands: Have moderate electrical conductivity for applications where weight is considered critical.
- Brass Cable Glands: Have high electrical conductivity, making them the cable gland of choice for the most demanding electrical systems.
4. Weight
- Aluminium Cable Glands: Lightweight, which makes it very suitable for applications where equipment weight needs to be as light as possible.
- Brass Cable Glands: Heavier, yet tougher, providing enhanced mechanical strength.
5. Cost
- Aluminium Cable Glands: Relatively cheaper, as aluminium costs less compared to the basic raw material.
- Brass Cable Glands: Expensive usually, but prove to be more durable and valuable over time.
Benefits of Aluminium and Brass Cable Glands
Benefits of Aluminium Cable Glands
- Light weight and easily manageable.
- Cheap for bulk projects.
- In non-corrosive environments; resistant to oxidation.
- Suitable for lighter applications like in aerospace, electronics, etc.
Advantages of Brass Cable Glands
- Exceptional strength and durability.
- Excellent resistance to corrosion and harsh environmental conditions.
- Excellent electrical conductivity for high-performance systems.
- Ideal for heavy-duty industrial, marine, and outdoor applications.
Applications of Aluminium and Brass Cable Glands
Aerospace: Lightweight nature reduces the overall weight of aircraft components.
- Electronics: Suitable for use in lightweight electronic devices and systems.
- Non-Corrosive Environments: Ideal for indoor installations and controlled environments.
Applications of Brass Cable Glands
- Marine: High resistance to saltwater corrosion, ideal for vessels
- Industrial Plants: For very harsh conditions in industries.
- Outdoor Equipment: Performs satisfactorily under extreme conditions
- Power Generation: It can be used in electrical systems of high voltage.
How to Select Between Aluminium and Brass Cable Gland
Environmental Conditions:
- Aluminium cable gland to be selected for the environment, which is noncorrosive.
- Brass cable gland to be used in harsh industrial and marine environments.
Weight Conditions:
- Aluminium is perfect for applications where weight saving is important.
- Brass is suited for applications that need robustness and reliability.
Electrical Requirements:
- Aluminium has average conductivity.
- Brass is the best suited for high conductivity.
Budget:
- Aluminium is better for big projects as it is cheaper.
- Brass gives the best value for money since it is durable.
Top 10 Things to Look for When Selecting Cable Glands
- Material: Know whether Aluminium or brass is suitable for your use.
- Durability: Brass is more durable, and Aluminium is light.
- Corrosion Resistance: Brass is suitable for corrosive conditions; Aluminium may need to be coated.
- Electrical Conductivity: Brass is more conductive.
- Weight: Aluminium is lighter; brass is heavier but stronger.
- Temperature Resistance: Both materials are resistant to temperature changes, but brass is stronger.
- Cost: Aluminium is cheaper, brass is cost-effective in the long run.
- Application Environment: Consider indoor versus outdoor or industrial versus marine use.
- Ease of Installation: Aluminium is easier to install because it is lighter.
- Maintenance: Brass has minimal maintenance compared to aluminium in harsh environments.
Conclusion
There is a choice between Aluminium and Brass cable Glands. Aluminium glands are lightweight and cost-effective, hence ideal for indoor and non-corrosive environments. Brass glands, on the other hand, provide unmatched durability, corrosion resistance, and conductivity, making them the most preferred for heavy-duty and outdoor applications.
