Platinum and iridium alloys for the shipbuilding industry

1, Iridium alloys in reactor materials for nuclear-powered ships as nuclear fuel cladding materials or control rod assemblies.

2, Platinum-iridium alloys for spark plug electrodes can enhance component life and reduce failure rates due to corrosion.

3, Platinum group metal catalyst alloys.

4, Marine electronic equipment (such as radar, navigation systems) connectors, circuit board plating.

5, Relay contacts, conductive pastes and silver-tin oxide alloy switches in marine power systems.

6, ship engine high temperature monitoring system in the platinum-rhodium (Pt-Rh) thermocouple.

7, Corrosion resistant palladium alloy valves for marine fuel systems.

8, Coated titanium anodes for seawater electrolysis.

Platinum alloys in other industries

Platinum alloy is irreplaceable in the field of catalysis, platinum is the core catalyst for proton exchange membrane fuel cells; platinum-rhodium alloy in high temperature environment performance is very good, PtRh10/Pt thermocouple can be measured accurately 630.74 ~ 1064.43 degrees Celsius, a short period of time can be up to 1,600 degrees Celsius; platinum-rhodium alloy crucible can withstand 160 degrees Celsius molten glass, the life of up to several years.

Iridium alloys in other industries

Platinum-iridium alloys are excellent in strong corrosive environments, containing 30% iridium platinum-iridium alloys are virtually insoluble in boiling aqua regia, while pure platinum dissolves at a rate of 0.1mm/year under the same conditions; platinum-iridium alloys containing 25% iridium hardness up to 200 HV, 3 times that of pure platinum, and tensile strength up to 1000 MPa; platinum-iridium alloys (e.g., PtIr25) with extremely low contact resistance are used for aircraft engine ignition The contact resistance of platinum-iridium alloys (such as PtIr25) is extremely low, which is used in aircraft engine ignition points, and the service life is extended to over 100,000 times.
