Material properties

Aluminum (Al) is a silvery-white, lightweight metal with excellent ductility, electrical conductivity, and thermal conductivity. It is chemically reactive and forms a dense oxide film on its surface in air, thus providing corrosion resistance. Aluminum is amphoteric, soluble in both strong alkalis and dilute acids, but it is passivated in cold concentrated nitric acid/sulfuric acid.

Technological advantages

1.  Laser cutting：Its main features are high precision, high efficiency, strong material adaptability and low loss. It achieves non-contact processing through focused beam, can cut complex shapes without molds, and has good cutting quality (smooth edges). It is widely used in the automotive, aerospace and medical industries, and is particularly suitable for fine, complex and large-scale processing needs.。 
2. Bending：It reduces the number of parts and post-processing (eliminating welding and simplifying logistics), improves efficiency and flexibility (enabling mass production and customization, and rapid changeover), offers high precision (especially in CNC bending), reduces costs (eliminating the cost of connectors and welding), and allows for the fabrication of complex shapes and the integration of materials into a single piece.

3. Black anodizing：Black anodized aluminum boasts exceptional wear resistance, scratch resistance, and superior corrosion resistance, resulting in a matte, high-end appearance. Furthermore, the oxide layer is firmly bonded to the aluminum substrate, making it resistant to peeling. It not only possesses good thermal stability (suitable for high-temperature applications) and light absorption (suitable for electronic housings), but also offers advantages such as environmental friendliness, weather resistance, high color retention, and cost-effectiveness.

Surface treatment

The main processes used include anodizing, spraying (baking paint), electroplating, wire drawing, and sandblasting to form a protective film on the surface, thereby improving corrosion resistance, hardness, wear resistance, and aesthetics to meet different functional requirements. This method is commonly found in electronics products, building materials, and other fields. The main methods include mechanical treatment (sandblasting, wire drawing, polishing), electrochemical treatment (anodizing, electrophoresis), and chemical treatment (phosphating, chromating), among which anodizing and fluorocarbon baking paint are the most widely used.

Application performance

Aluminum keyboards (CNC aluminum alloy keyboards, commonly known as "aluminum lumps") are primarily used in mid-to-high-end offices, e-sports games, personalized customization enthusiast circles, and mobile office scenarios where quality of life and compact space are desired, due to their ultimate metallic texture, solid typing feel, and excellent Hi-Fi sound performance.
