Titanium-magnesium alloy frames are currently the most durable glass door frame material, especially excelling in wind pressure resistance, corrosion resistance, and stability, making them suitable for demanding home and engineering projects.
Titanium-Magnesium Alloy: High Strength and Excellent Weather Resistance
High-Strength Structure: Titanium-magnesium alloy combines the high strength and toughness of titanium with the lightweight advantages of magnesium. Its tensile strength is 30%–50% higher than that of ordinary aluminum alloy, effectively resisting deformation caused by strong winds and vibrations.
Strong Adaptability to Extreme Environments: In windy and sandy areas like Inner Mongolia with large temperature differences, the coefficient of thermal expansion of titanium-magnesium alloy is 60% lower than that of ordinary aluminum alloy, almost eliminating gaps caused by temperature fluctuations, ensuring long-term airtightness and stability.
Excellent Corrosion Resistance: After electrophoretic coating treatment, it possesses extremely strong resistance to salt spray and oxidation, and is not prone to rusting even in humid or coastal environments.
Long Service Life: High-quality titanium-magnesium alloy frames with a wall thickness of up to 2.0mm, combined with high-strength tempered glass, ensure stable use for over 10 years, far exceeding ordinary aluminum alloys.
Aluminum Alloy: High cost-performance ratio, mainstream choice.
Widely Applicable: Anodized 1.5–2.0mm thick aluminum alloy frames are currently the mainstream in the market, possessing good strength and corrosion resistance, suitable for most home environments.
Mature Technology: Utilizing anodizing or electrophoretic spraying processes, the surface is smooth and not prone to paint peeling, supporting ultra-narrow bezel designs (e.g., 1.6–3cm), enhancing the sense of spaciousness.
Limitations: In extreme climates or high humidity environments, performance is slightly inferior to titanium-magnesium alloys.
Stainless Steel: Suitable for specific scenarios.
Preferred for High Humidity and Corrosion Environments: 304 stainless steel frames perform excellently in high-humidity spaces such as bathrooms and swimming pools, exhibiting extremely strong corrosion resistance.
The disadvantages are obvious: heavy weight, high cost, limited design options, and strong thermal conductivity, which makes it prone to condensation in winter, affecting the user experience.
