Polished Sapphire Rods

We supply diverse diameters, lengths and crystal orientations including C‑cut, A‑cut and R‑cut, supporting custom sizes and end‑face processing to match project demands. Widely adopted in optical systems, medical instruments, precision machinery, semiconductor equipment, analytical sensors and high‑pressure pump plunger components. Strict quality inspection guarantees consistent surface quality and stable batch performance. Small‑batch trial orders and large‑volume wholesale are both welcome for global B2B buyers.

– Domed Head Sapphire Rods: Low-friction design for reciprocating motion and optical transmission
– Flat Head Sapphire Rods: For precise positioning and pressure bearing assembly
– Cone Sapphire Rods: Tapered structure for guiding and sealing fitting
– Sapphire Plungers: Wear-resistant core parts for high-pressure HPLC pumps
– Wedged Sapphire Rods: Special wedge shape for limit guiding and customized assembly
– Double-end Open Sapphire Tubes: For fluid delivery and light transmission systems

product details

Diameter:0.5mm to 200mm. Length:0.5mm to 300mm(KY). 0.5mm to 1500mm(EFG)

Surface Quality: Polished（Ra 0.02μm）

Our polished sapphire rods are manufactured from high‑purity single‑crystal alumina (Al₂O₃), delivering premium surface finish with tight dimensional tolerances for industrial and optical‑grade applicationsMade-in-Ch…. Boasting Mohs 9 hardness, outstanding scratch‑proof and wear‑resistant performance, these rods withstand extreme high‑temperature conditions and resist most acids, alkalis and chemical corrosion. They feature broad optical transmission covering UV, visible to mid‑infrared spectrum, plus excellent thermal stability and electrical insulation capacity.
