Precision Micro Sapphire Rods
applications in bioengineering, dental procedures, and medical bone implants
Micro Sapphire Rods employed in pumps, including HPLC piston/plunger rods, as well as in lamps, gaskets, insulators, and wear applications.
Our product range includes cylindrical rods, sapphire tapered rods, and sapphire tips/needles, with the capability to manufacture micro sapphire rods as small as 0.3mm.
Widely employed in medical devices, precision machinery, and inspection instruments, micro sapphire rods are highly valued for their exceptional properties, which include high hardness, strength, scratch resistance, high-temperature resilience, purity, chemical durability, and superior radiation stability.
Micro sapphire rods prove ideal for high-temperature applications, retaining their shape and dimensions due to an extremely high softening point that exceeds 2000°C. These rods are chemically inert and withstand attacks from most processing environments, including acids and alkalis at temperatures of up to approximately 1,000°C.

Application of Micro Sapphire Rods
Micro sapphire rods are renowned for their outstanding chemical and plasma resistance, making them exceptionally well-suited for diverse applications.
The remarkable chemical resistance of sapphire rods, especially at elevated temperatures, positions them as excellent choices for applications in plasma chambers. Notably, only hot caustic salts possess the potential to etch sapphire rods, while other solvents, acids, and caustics have no impact on sapphire, including molten metals. This unique property ensures the safe handling and processing of chemicals within a chemically pure environment.
The chemical and bio-inert characteristics of sapphire rods make them ideal for critical applications in medical, pharmaceutical, semiconductor, and various industries where maintaining purity and health is of utmost importance.
Supported sapphire rods exhibit the ability to withstand temperatures up to 2000°C without significant alteration in shape and with minimal impact on mechanical performance. In high-temperature furnace systems, sapphire rods serve as excellent choices for rollers and standoffs, maintaining their straightness and dimensional precision up to 1800°C. Sapphire’s exceptional chemical resistance prevents many materials from adhering to it, even at elevated temperatures.
Sapphire rods hold the highest temperature rating among all optical materials, preserving their integrity in both oxidizing and inert atmospheres.
