Cemented carbide products prices have been raised
The reason for the current increase in the prices of cemented carbide products is still the continued rise in the prices of the main raw materials tungsten and cobalt. According to reports, most of the mines were forced to stop production or rectification due to the tightening of the implementation of environmental protection policies by the country last year, and the supply of mineral resources such as tungsten, molybdenum, and rare earths. The majority of mines are still shut down. At the same time, because China supplies about 80% of the world's tungsten raw materials, the reduction in output has led to the reversal of the market's supply and demand relationship, which has changed from a seller's market to a buyer's market.

What is the difference between cemented carbide and tungsten steel?
Tungsten steel: 18% alloy steel containing tungsten in the finished product. Tungsten steel is classified as cemented carbide, also called tungsten titanium alloy. The hardness is 10K Vickers, second only to diamonds. Because of this, the products of tungsten steel (the most common ones are tungsten steel watches) have the characteristics of not being easily worn. Commonly used on lathe tools, impact drill bits, glass cutter bits, and ceramic tile cutters, they are strong and not afraid of annealing, but they are brittle.
