Tungsten is a rare and valuable metal used in various industrial applications, including electronics, mining, and aerospace. In recent years, the price of tungsten has been volatile due to fluctuations in supply and demand. According to the United States Geological Survey (USGS), the price of tungsten concentrate (65% WO3 minimum) in the United States in 2020 was around $245 per metric ton unit (MTU), up from around $210 per MTU in 2019.

Cobalt is a metal used primarily in the production of rechargeable batteries for electric vehicles and other electronics. Like tungsten, cobalt prices have been volatile in recent years due to fluctuations in supply and demand. According to the London Metal Exchange (LME), the average cash price for cobalt in 2020 was around $14 per pound, down from around $16 per pound in 2019.

It's important to note that prices for raw materials can vary widely depending on factors such as location, quality, and supply and demand dynamics. If you need up-to-date information on current prices for these materials, I would recommend checking with a reliable source such as a commodity pricing service or market research firm.
