Metal prices
Metal prices are only for a few metals quoted on exchanges. Only aluminium alloy, aluminium, copper, lead, nickel, tin, zinc and Nasaac are exchange traded commodities. Other metals are traded on market demand and the buyers/sellers themselves set the price.
The London Metal Exchange which trades the commodities mentioned above is planning to add trading contracts for cobalt and molybdenum in the course of 2009/2010.
Contracts traded on metal exchanges are also called futures contracts.
Pricing providers
There are companies which provide a pricing service set the price by talking to producers, traders and consumers. These prices are more an indication than an actual exchange price.Unlike the prices on an exchange, pricing providers tend to give a weekly or bi-weekly price. For each commodity they quote a range which reflect the buying and selling rbout 9-fold due to China's transition from light to heavy industry and its focus on manufacturing.
Metal commodities
The commodities quoted have a specific grade and quality of the forms in which they are most often traded.An example:
| Commodity | Cobalt |
| Traded forms | Cobalt min 99.3% Russian Cobalt min 99.8% - aerospace application |
Cobalt is an important export product of Russia and therefore the Russian quality is often traded. Another form of cobalt crucial to the aerospace industry is a high grade form of cobalt with 99.8% purity.
