Tihotoptics specializes in custom aluminosilicate glass fabrication for advanced industrial and commercial applications. Our lead-free, high-strength glass components are engineered to meet the demands of electronics, aerospace, medical, laboratory, and optical systems. Whether you require ultra-thin, impact-resistant, or heat-stable aluminosilicate glass, we offer complete OEM solutions tailored to your technical drawings and performance requirements.
What Is Aluminosilicate Glass?
Aluminosilicate glass is a high-performance silicate glass composed of silicon dioxide (SiO₂) and aluminum oxide (Al₂O₃), enhanced by alkali and alkaline earth oxides. This unique composition results in:
- Exceptional thermal stability
- High mechanical strength
- Scratch and impact resistance
- Superior chemical durability
It is widely used as a durable alternative to soda lime and borosilicate glass, especially in applications where strength, thinness, and precision are critical—such as smartphone cover glass, touch panels, aerospace sensors, and lab instrumentation.
Why Choose Custom Aluminosilicate Glass?
Unlike standard glass materials, custom aluminosilicate glass offers:
- Up to 5x the strength of soda-lime glass
- Enhanced resistance to thermal shock and mechanical stress
- Available in ultra-thin sheets down to 0.3 mm
- Compatible with chemical strengthening and ion exchange processesExcellent optical clarity and transmission
By customizing aluminosilicate glass to your specs, you gain maximum control over thickness, geometry, surface quality, and performance, ensuring it integrates seamlessly into your devices or systems.
