rhodium
Catalytic converter metal
Rhodium is a rare, silvery-white metallic element used primarily in catalytic converters and as a plating material for jewelry and mirrors.
It belongs to the platinum group of metals and is among the most expensive precious metals by weight.
Its exceptional resistance to corrosion and ability to reflect light make it valuable for industrial and decorative applications.
