? Precious metals are ranked as follows:
1, rhodium
Features: Hard and corrosion resistant.
Rhodium is extremely rare. Rhodium has a high melting point and amazing corrosion resistance. This silvery white metal is usually used because of its reflective properties, and its price is about four times that of gold. It is usually used in lighting industry and catalyst.
2. palladium
Features: Low melting point density.
Palladium is the second most expensive metal in the world, about 30 times rarer than gold or platinum. It is very valuable and is often used in catalytic converters of diesel vehicles, as well as electronics, groundwater treatment, hydrogen purification and so on.
3. golden
Features: Extensible and durable.
Jin Su has the title of "King of Metals", which is no stranger to everyone. The market demand has always been great, and it is often used in jewelry design and plays an important role in aerospace, medicine and other industrial fields.
4. Iridium (Ir)
Features: corrosion resistance, high melting point.
Iridium is the most extreme member of the platinum group and one of the most corrosion-resistant metals, and its melting point is very high. Usually used in metallurgy, medicine, automobile industry, electronics, aviation and other fields.
5. Platinum
Features: Not affected by high temperature.
Platinum is a natural white precious metal, commonly known as platinum and pure white gold. It is one of the most valuable metals in the world, and is usually used to make jewelry and laboratory equipment for many industrial applications.
