Surface-polished synthetic sapphire rods and sapphire ingots are precision-engineered materials made from single-crystal aluminum oxide (Al₂O₃). Synthetic sapphire is known for its exceptional hardness, second only to diamond, and its ability to withstand extreme temperatures and harsh environments. The polishing process enhances the surface quality, making it ideal for applications that require high optical clarity and smoothness.
One of the standout features of synthetic sapphire is its high dielectric constant, which makes it an excellent electrical insulator. This property, combined with its mechanical strength and chemical resistance, makes sapphire rods and ingots ideal for use in a wide range of industries, including electronics, optoelectronics, and aerospace.
Sapphire rods are commonly used in optical systems, lasers, and high-precision equipment, while sapphire ingots are used as the base material for slicing into wafers for semiconductor and LED manufacturing. The material’s transparency to UV and infrared light also makes it a preferred choice for windows and lenses in high-performance optical devices. Overall, surface-polished synthetic sapphire components are critical in applications where durability, precision, and insulating properties are required.

Q6: Do you accept OEM?
A: We have our own brand-metalaser. OEM is also acceptable.
Q7:What is a sapphire rod?
A:A sapphire rod is a cylindrical form of synthetic sapphire, which is a crystalline form of aluminum oxide (Al₂O₃). Sapphire rods are known for their exceptional hardness, second only to diamond, and their resistance to high temperatures, chemical corrosion, and electrical insulation. These rods are often used in applications that require durability and stability under extreme conditions, such as in optics, lasers, high-temperature furnaces, and scientific instrumentation. They can also be used in precision machining, bearings, and medical devices due to their mechanical strength and biocompatibility.
