Our precision-engineered magnesium alloy laptop housing represents the forefront of lightweight structural components for modern computing devices. Manufactured using advanced thixomolding technology and CNC machining processes, these housings combine exceptional strength-to-weight ratios with superior electromagnetic interference protection. The manufacturing process involves heating magnesium alloy to a semi-liquid state before injection into precision molds, creating large, complex components with minimal material waste compared to traditional CNC aluminum machining.
The magnesium-lithium (LZ) alloy formulation significantly enhances room-temperature formability, addressing the traditional challenges associated with magnesium alloy processing. This innovation allows for the production of thin-walled structures as slender as 0.6mm while maintaining structural integrity, making these housings ideal for today's ultra-thin laptop designs.

Lightweight Structural Solution
Magnesium alloy's density of approximately 1.8 g/cm³ makes it 30-50% lighter than equivalent aluminum components. This significant weight reduction enhances portability without compromising structural integrity, with finished products maintaining thickness below 18mm for standard configurations and under 21mm for discrete graphics models.
Enhanced Manufacturing Efficiency
The thixomolding process enables production of single-piece magnesium alloy components with complex structural features. This advanced manufacturing approach eliminates the material waste associated with traditional CNC machining from solid blocks, with 90% post-industrial recycled magnesium alloy content in the final product.
Superior Functional Performance
Our magnesium alloy housings provide complete electromagnetic interference absorption exceeding 100dB, eliminating the need for additional conductive coatings. The material's excellent thermal conductivity efficiently dissipates heat from internal components, maintaining optimal operating temperatures.
