Sapphire Tapered Rods
applications in bioengineering, dental procedures, and medical bone implants
Sapphire Rods are used in a wide range of applications. A sapphire rod can be made with all surfaces polished for optical and wear applications or with all surfaces fine grind (un-polished) to serve as an insulator. Sapphire Rods are available in a range of outer diameter and lengths. OD's as small as 0.3mm.
As a leading OEM supplier of custom Sapphire Tapered Rods, we offer a wide range of precision-engineered solutions for applications including ram pumps, plunger rods, laser rangefinders, laser designators, insulators, and precision measuring tools. Our advanced manufacturing capabilities allow us to produce custom sapphire rod geometries such as cylindrical rods with a single tapered cone, double flat conical ends, or multi-surface flat cones, tailored to meet your exact specifications.
Sapphire tapered rods are well known for their exceptional chemical and plasma resistance, making them highly suitable for a wide range of applications. The impressive chemical resistance of sapphire tapered rods, particularly at elevated temperatures, positions them as optimal choices for use in plasma chambers. This distinct property ensures the secure handling and processing of chemicals within an environment of chemical purity.
Sapphire tapered rods demonstrate the capability 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 excel as excellent options 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.

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.
