Standard purity grades include 99.90%, 99.95% and 99.99%. Higher purity materials can be supplied for semiconductor manufacturing, crystal growth and scientific research applications.
Iridium rods are available in diameters from approximately 1 mm to 100 mm. Larger diameters or custom dimensions can be manufactured according to customer drawings and technical requirements.
Yes. Standard lengths and fully customized lengths are available. Precision cutting services can also be provided to meet specific application requirements.
Surface finishes include as-forged, turned, centerless ground, polished and precision-machined finishes depending on dimensional tolerance and application requirements.
Yes. Iridium rods can be machined using advanced CNC turning, milling, grinding and EDM processes to manufacture precision components with tight dimensional tolerances.
Iridium rods are widely used in semiconductor manufacturing, sapphire crystal growth, aerospace engineering, laboratory equipment, electrochemical systems, medical technology and scientific research.
Iridium has an extremely high melting point of approximately 2446°C, excellent oxidation resistance and outstanding mechanical stability, making it suitable for demanding high-temperature environments.
Iridium rods offer higher melting temperature, greater hardness and better wear resistance than platinum rods, while platinum provides superior ductility and easier fabrication.
Yes. Iridium rods can be joined using specialized welding processes such as electron beam welding, laser welding or TIG welding under carefully controlled conditions.
Yes. Iridium is one of the most corrosion-resistant metals available and exhibits excellent resistance to acids, alkalis, oxidation and many aggressive chemical environments.
Yes. Iridium rods are suitable for high-temperature vacuum furnaces and inert-gas atmospheres where excellent thermal stability and low contamination are required.
Yes. Sunny Steel manufactures custom iridium shafts, pins, electrodes, spacers, fixtures and other precision-machined components according to customer drawings.
Machining tolerances depend on product size and geometry. Precision tolerances can be achieved through CNC machining, grinding and finishing processes according to customer specifications.
Yes. Due to their excellent corrosion resistance and high-temperature stability, iridium rods are widely used as electrodes in electrochemical, analytical and industrial processing equipment.
Products are inspected for chemical composition, dimensional accuracy, surface quality and overall workmanship. Additional testing can be performed according to customer requirements.
Yes. Third-party inspection services from organizations such as SGS, BV and TÜV are available upon request before shipment.
Iridium rods are individually protected using anti-scratch packaging and moisture-resistant materials before being packed in strong export-grade cartons or wooden cases suitable for international transportation.
Yes. Because iridium is a high-value precious metal, used rods and machining scrap can normally be recycled and refined to recover valuable material.
Pure iridium has a density of approximately 22.56 g/cm³, making it one of the densest metallic elements.
Iridium has a melting point of approximately 2446°C (4435°F), making it one of the highest melting precious metals used in industrial applications.
