Rare metal rhenium gold: the successor of iridium and rhodium.
Rhenium, iridium and rhodium are rare metals with very low global reserves, and the reserves of rhenium are more scarce than iridium and rhodium, and their discovery and application are much later than iridium and rhodium
1.Physical and Chemical Properties:
Rhenium: Has the highest boiling point and the third highest melting point, it is a rare silvery-white metal. It is named after the Rhine and is a key element in the aerospace and energy sectors.
Iridium: 12 times thinner than ** in the earth's crust, with a high density. It is commonly used for hardening platinum, has a high melting point, is hard and brittle, and is not easy to handle.
Rhodium: As a member of the platinum group, it is a brittle metal that is usually found in powder form. It is commonly used in electrical contacts and catalytic converters and can harden palladium and platinum alloys.
2.Applications:
Rhenium: occupies a central position in the manufacture of aero engines, especially the turbine blades and exhaust nozzles of jet engines.
Iridium: Able to withstand extremely high temperatures in industrial and medical devices, and although found in rare quantities in the earth's crust, iridium-rich clay has been found at the site of meteorite impact.
Rhodium: In addition to its wide range of applications in catalytic converters and high-end jewelry, rhodium-plated items are wear-resistant and appealing.
3.Value & Volatility:
Rhodium: In 2008, the rhodium price soared to $10,000 an ounce, but by 2013 it had sharply** fallen below $1,000. This shows the rising volatility of the rare metals market.
Iridium and rhenium: Due to their rarity and key role in specific fields, their ** with the progress and development of science and technology and relatively stable and continuous**, among which rhenium because of its short time and wide use, its upside and potential are greater than iridium.
In general, these three metals have unique characteristics and application value, and all have great value, as a latecomer, rhenium is constantly catching up with the pace of rhodium and iridium!
