The three platinum group metals (PGM) are essential in catalytic converter buying, and Techemet’s TechPrice app helps you get prices, get alerts, and calculate converter prices based on current PGM prices. Our app shows the prices for Platinum, Palladium, and Rhodium in real time for information purposes. You can also see historical prices for the past three months. We also know that you want to stay on top of the PGM prices, so our app pushes alerts to you when the prices move. As a bonus, we included a converter calculator to help estimate a converter's value based on their PGM assay and the current prices of the metals. Techemet LP is a smelter and recycler of platinum group metals. Our main function is the recovery of PGM metals from scrap automobile catalytic converters and spent petrochemical catalyst.
