1. Basic Physical Properties of Platinum-Iridium Alloys

Alloy Grade	Melting Point (°C)	Density (g/cm³)	Hardness (HV)	Tensile Strength (MPa)
PtIr10	1840	21.45	Hardened: 185 Annealed: 140	625–1150
PtIr20	1840	21.45	Hardened: 260 Annealed: 195	625–1150

2. Marine Application Selection Comparison

Requirement	Recommended Grade	Advantages
Extreme corrosion	PtIr20	40% higher hardness, doubles sealing life in ship valves
Micro-current sensing Weak electrical contacts	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
