DONGSHENG recycles platinum iridium alloy scrap from shipbuilding, including marine PtIr10/PtIr20 sensors, electrodes, and corrosion-resistant components. Platinum-iridium alloy recycling prices are assessed based on wear conditions. We offer premium prices for brands like Sandvik.
Alloy Grade | Melting Point (°C) | Density (g/cm³) | Hardness (HV) | Tensile Strength (MPa) |
PtIr10 | 1840 | 21.45 | Hardened: 185 | 625–1150 |
PtIr20 | 1840 | 21.45 | Hardened: 260 | 625–1150 |
Requirement | Recommended Grade | Advantages |
Extreme corrosion | PtIr20 | 40% higher hardness, doubles sealing life in ship valves |
Micro-current sensing | PtIr10 | Lower resistivity (1.2 μΩ·m), 15% signal stability improvement |
Cost-sensitive parts | PtIr10-clad titanium | 50% less precious metal usage, meets industrial corrosion resistance requirements |
