What are the material selection criteria for aluminum mechanical keyboard case ?
When selecting
Aluminum Housing materials for mechanical keyboards, the following criteria and factors are usually considered:
Mechanical properties:
Strength and hardness: Aluminum needs to have sufficient strength and hardness to resist wear and impact in daily use.
Ductility: Proper ductility helps to form complex shapes during processing without breaking easily.
Processing properties:
Easy cutting and forming: High-quality aluminum alloys should be easy to perform with precision cutting and forming operations using CNC machines.
Surface treatment compatibility: The selected material should be suitable for various surface treatment processes, such as anodizing, sandblasting, etc.
Corrosion resistance:
Antioxidant capacity: Good antioxidant properties can extend the service life of the product and keep it beautiful.
Chemical resistance: Resistance to chemicals is also an important consideration for products that may come into contact with cleaners or other chemicals.
Thermal conductivity:
Efficient heat dissipation: In some application scenarios, good heat conduction performance can help the keyboard better heat dissipation, especially in the case of long-term high load work.
Appearance quality:
Gloss and flatness: High quality aluminum provides better surface gloss and fewer blemishes, making the final product more beautiful.
Acceptable color range: Different aluminum alloys can show different color effects after anodizing, and the selection should consider whether it can meet the design requirements.
Cost effectiveness:
Economy: Although high performance materials tend to be more expensive, the relationship between cost and desired performance needs to be balanced to achieve the best value for money.
Environmental protection:
The recyclability of materials and the environmental impact of the production process are also factors of increasing importance in modern manufacturing.
Industry standards and certifications:
Ensure that selected materials comply with relevant industry standards (such as ISO 9001) and that necessary certifications (such as RoHS compliance) are available.
The common aluminum alloys used for mechanical keyboard shells are 6061 and 6063, which are widely used because of their good comprehensive properties. Among them, 6061 has better mechanical properties and weldability, and 6063 is more commonly used in the production of complex shapes and beautiful products because of its excellent extrusion performance and surface finish. The choice of material depends on the specific application scenario and design requirements.
