What is the material selection standard of tablet computer shell aluminum?
When choosing aluminum alloy material for tablet housing, the following key criteria and factors are usually considered:
Mechanical properties: including strength, hardness, ductility, etc. For the shell, it needs to be strong enough to protect the internal components from physical damage, but also flexible enough to prevent breakage when dropped or impacted.
Weight: An important advantage of aluminum is its relatively low density, making it ideal for making lightweight devices. Therefore, in the selection of materials will be inclined to those that can provide a good strength to weight ratio of alloys.
Thermal conductivity: Aluminum alloy has good thermal conductivity, which helps to effectively dissipate the heat generated inside the equipment and maintain the good operating condition of the equipment.
Corrosion resistance: In order to ensure that the shell can be used for a long time under different environmental conditions without being corroded, the selected aluminum should have good corrosion resistance. Corrosion resistance can be further improved by surface treatment such as anodizing.
Processing performance: When selecting materials, it is also necessary to consider whether the material is easy to cut, press, bend, weld and other processing operations. Good processing properties help to reduce production costs and improve production efficiency.
Appearance quality: including color consistency, gloss, and whether there are defects. Some high-end products may pay special attention to the appearance of the material, such as the use of specific surface treatment techniques (such as anodizing, wire drawing) to enhance the visual appeal of the product.
Environmental requirements: In consideration of environmental protection and sustainable development, the selected materials should comply with the requirements of relevant environmental regulations, such as the absence of environmentally harmful substances.
Common aluminum alloys for electronic equipment enclosures are 6000 series (such as 6061, 6063), and these alloys are widely used in consumer electronics products because of their good comprehensive properties. In practical applications, manufacturers may choose the most suitable aluminum alloy model based on specific design needs and cost considerations.
