Electronic Application Industry

Aluminum has excellent thermal conductivity and is an efficient thermal management material. Aluminum has a high thermal conductivity, which can quickly transfer the heat from point heat sources (such as CPU and GPU chips) to the whole shell or heat dissipation fins, and then dissipate it into the air through convection and radiation. This is very important for modern electronic equipment with increasingly strong processing capacity and higher power consumption, and can effectively prevent the equipment from frequency reduction or damage due to overheating. Compared with copper with better thermal conductivity, aluminum has obvious advantages in cost and weight.

In addition, it has first-class electromagnetic shielding performance, which can provide effective electromagnetic interference (EMI) and radio frequency interference (RFI) shielding. Electronic products have dense internal components and numerous high-frequency signals, which are prone to electromagnetic interference. Metal aluminum is a good conductor, which can form a "faraday cage", effectively isolating the internal sensitive circuit from external interference, and at the same time preventing the electromagnetic signal of the equipment from leaking out, ensuring the stable operation of the equipment and passing the electromagnetic compatibility (EMC) certification. Stamped aluminum shield is a common part on the motherboard.

Non-magnetic aluminum will not interfere with the magnetic sensitive elements of the equipment. Aluminum is not ferromagnetic, which means that it will not interfere with the compass, Hall sensor, speaker and other components inside the equipment, ensuring the normal working accuracy of these components.

More importantly, aluminum is 100% recyclable, which conforms to the concept of green manufacturing. The energy required for recycling remelted aluminum is only about 5% of that for producing new aluminum, and its performance is not degraded. This is a great attraction for modern electronic enterprises pursuing environmental protection and sustainable development, which helps to reduce the carbon footprint and cost of products.
