Is rhodium plating good?
While rhodium is both too expensive and too brittle to make jewelry out of, it makes an excellent plating material. Being harder than both silver and gold, it also makes an excellent protective coat that shields jewelry from scratches.
Why is rhodium so expensive 2021?
Since rhodium is a by-product, its supply doesn’t increase when there’s a deficit in the market and this leads to prices spiking. Rhodium usually trades at below $1,000 per troy ounce, but these deficits pushed the prices to record levels of almost $30,000 per troy ounce in 2021.
Why is rhodium used in catalytic converters?
The main use for rhodium is in catalytic converters designed to clean vehicle emissions. Rhodium — often together with palladium and/or platinum — accomplishes this by reducing nitrogen oxide in exhaust gas. Without rhodium catalysts, the air in our cities would be much worse due to vehicle exhausts.

Will rhodium turn skin green?
Does rhodium tarnish? Rhodium is nickel-free, so it does not tarnish. Rhodium is also corrosion-resistant and does not rust. Because rhodium is strong, it does not need to be alloyed with other metals like nickel or copper that, over time, will corrode and leave behind dark green marks on your skin.
Is rhodium expected to rise?
Rhodium supply is expected to rise to nearly 990,000 oz in 2021 from 905,000 oz in 2020 because of increases in mine output and scrap supply. However, rhodium is expected to remain in a surplus in 2021 of about 25,000 oz, similar to the surplus in 2020.
Will rhodium continue to drop?
Despite the outlook for improving supply, we still expect rhodium to remain in deficit until 2025.”
How much rhodium is in a catalytic converter worth?
Each converter generally contains about $400 worth of rhodium, he said, in addition to its numerous other components.
Why is rhodium so expensive?
