FAQ

How much does it cost to extract aluminium from its raw ore? Also how much does extracted aluminium sell for? I cannot find this anywhere on the internet. I would really appreciate some help.

The biggest cost is the electricity. This is why most Al smelters are located where electricity is cheap. The price of Al metal depends on exactly what form it is in and what the alloy is. Scrap Al is worth very roughly $0.30 per pound. Fabricated Al alloys for aerospace applications sell for much much more. Ultra high purity Al for semiconductors sells for roughly $40 per kg.

Yes, aluminum coils can be used in building facades. Aluminum is a popular material choice for building facades due to its numerous benefits. It is lightweight, durable, and corrosion-resistant, making it suitable for exterior applications. Aluminum coils can be formed into various shapes and sizes, allowing for creative and versatile design possibilities. Additionally, aluminum is available in a wide range of finishes, including anodized, painted, and coated, providing further customization options for building facades. Moreover, aluminum is a sustainable material as it is 100% recyclable, making it an environmentally friendly choice for construction projects. Overall, aluminum coils are a viable option for building facades, providing both aesthetic appeal and functional performance.

Aluminum coils have a relatively high electrical conductivity. Renowned for its impressive conductivity, aluminum boasts a rating of approximately 37.7 x 10^6 siemens per meter (S/m). As a result, aluminum is an exceptional option for a range of electrical uses, particularly in coil production. The exceptional conductivity of aluminum facilitates the efficient transmission of electric current through the coils, rendering them a fitting choice for electrical wiring, transformers, motors, and other electrical apparatus.

Some common problems faced with aluminum coils include corrosion, poor heat transfer, refrigerant leaks, and coil damage due to mechanical stress or improper maintenance.

Saltwater environments do not pose a problem for aluminum coils as they possess outstanding resistance to corrosion. This is primarily due to the creation of a protective oxide layer on the aluminum surface, effectively acting as a shield against corrosion. By forming a barrier, this oxide layer prevents direct contact between the aluminum and saltwater, significantly reducing the likelihood of corrosion. Furthermore, aluminum itself has inherent resistance to saltwater corrosion as it is a relatively inert metal. Consequently, aluminum coils are widely utilized in various marine applications, including boat hulls, offshore structures, and saltwater cooling systems. Nevertheless, it is crucial to acknowledge that prolonged exposure to saltwater can still result in some degree of corrosion over time. To enhance the durability and performance of aluminum coils in saltwater environments, regular maintenance and suitable protective coatings are advised.

I can't figure out what the metabolic role of aluminum is. Been searching for a while and can't seem to find anything concrete.If you can, please include sources. Thanks!

I don't think it has any role.

Yes, aluminum coils can be used in marine or saltwater environments. Aluminum is highly resistant to corrosion, making it a suitable choice for applications in saltwater environments.

Aluminum coils are widely used in the production of consumer electronics for various purposes. One common application is in the manufacturing of heat sinks. Heat sinks are used to dissipate heat generated by electronic components, such as microprocessors, to prevent overheating and ensure optimal performance. Aluminum coils are often shaped into fins or plates and then attached to these components, as aluminum has excellent thermal conductivity properties. Another way aluminum coils are utilized in consumer electronics is in the production of electromagnetic shields. These shields are designed to block or redirect electromagnetic interference (EMI) generated by electronic devices. Aluminum, being a good conductor of electricity, is an ideal material for creating these shields. The coils are formed into various shapes and sizes, depending on the specific requirements of the electronic device, and then integrated into the product's design to minimize EMI. Furthermore, aluminum coils are used in the production of electrical connectors and wiring within consumer electronics. Aluminum is lightweight, durable, and has good electrical conductivity, making it an excellent choice for these applications. The coils are often processed and shaped into thin, flexible strips or wires that can be easily integrated into the electronic circuitry. In summary, aluminum coils play a crucial role in the production of consumer electronics by being used in heat sinks for thermal management, electromagnetic shields for EMI protection, and electrical connectors and wiring for efficient electrical conductivity. Their versatility, combined with their thermal and electrical properties, make them an essential component in the manufacturing process of various consumer electronic devices.
