Platinum-iridium tubes and rings are commonly requested for medical and precision device applications where radiopacity, corrosion resistance, and dimensional control are required. They may be used in marker bands, small rings, catheter-related components, and other precision assemblies. Final suitability should be confirmed according to the customer’s device design and regulatory requirements.
Platinum tubes are suitable for laboratory instruments, analytical equipment, electrodes, sensors, and other components that require chemical stability and high-temperature resistance.
Platinum and platinum alloy tubes may be used in electronic components, sensor assemblies, high-purity devices, and semiconductor-related applications where stable precious metal materials are required.
Pure platinum offers excellent resistance to many corrosive environments, making it suitable for selected chemical processing, experimental reactors, and corrosion-resistant components.
Platinum and platinum-based alloy tubes can be used in high-temperature environments where oxidation resistance, dimensional stability, and material reliability are important.
MetalsTek supports custom manufacturing based on drawings, samples, or technical specifications. For precision tubing and rings, we recommend confirming the following details before quotation:
| Question | Answer |
| Can you supply platinum-iridium tubes for medical applications? | Yes. Platinum-iridium tubes and rings are commonly requested for medical and precision device applications where radiopacity, corrosion resistance, and dimensional control are required. Final suitability should be confirmed according to the customer’s device design and regulatory requirements. |
| What platinum-iridium alloy ratios are available? | Common Pt-Ir alloy ratios such as PtIr 90/10 and PtIr 80/20 may be available. Customized compositions can also be reviewed according to drawing and quantity. |
| Can you cut platinum-iridium tubes into short rings or marker bands? | Yes. Pt-Ir tubes can be supplied as longer tubes or cut-to-length rings depending on OD, ID, wall thickness, tolerance, and surface requirements. |
| What information is needed for a quotation? | Please provide material, alloy composition, OD, ID, wall thickness, length, tolerance, quantity, surface requirement, and documentation needs. |
| Can you provide CoA or material certification? | Yes. CoA and related material documentation can be provided upon request, depending on the material grade and order requirements. |
| Can platinum tubes be customized with end caps or special shapes? | Yes. Custom shapes such as end-capped tubes, rings, capillary tubes, and tailored components may be manufactured according to drawings. |
| What is the difference between platinum tube and platinum-iridium tube? | Pure platinum offers excellent corrosion resistance and high-temperature stability. Platinum-iridium alloy is usually selected when higher mechanical strength, wear resistance, or radiopacity is required. |
| Is there a standard stock size list? | Some sizes may be available or previously manufactured, but most platinum and Pt-Ir tubes are quoted based on drawings or required dimensions. |
| Can you supply small OD capillary tubes? | Yes. Small OD capillary tubes can be reviewed according to material, wall thickness, tolerance, and quantity. |
| Do you support small-batch orders? | Small-batch orders may be available for certain materials and sizes. MOQ depends on alloy, dimensions, processing difficulty, and current production availability. |
Our platinum and platinum-iridium tubes are individually protected, clearly labeled, and packed to reduce deformation, surface damage, and contamination risk during storage and international shipment. For small rings, capillary tubes, or precision-cut parts, additional protective packaging can be arranged according to the size and handling requirements.
