As a strategic metal, tungsten is widely used in metallurgical machinery, petroleum chemistry, aerial and space industries and national defence engineering. So, today we are going to talk about tungsten supply and demand.

China has rich tungsten resources. During the past 10 years, China supplys more tungsten than the demand. By the end of 1998, China’s tungsten production capacity exceeded 35,000 tons. In recent years, the global demand for tungsten has been about 31,000 tons, whild China’s tungsten production in 1998 amounted to about 22,000 tons, making up 71% of the global tungsten demand.

At present, China’s domestic tungsten demand is about 8,000 tons and most of its tungsten is exported. While, excess tungsten exports have caused a decline in the global tungsten price, which is unfavorable to the development of China’s tungsten industry.
Varied international and domestic tungsten markets make it difficult to accurately predict the future demand for tungsten.
It is necessary to maintain and give full play to tungsten superiority to guarantee a sustainable development of China’s tungsten industry.
Above is about tungsten supply and demand.

The high density of tungsten heavy alloys makes it possible to significantly reduce the physical size of components. This in turn, gives the benefit of greater control of weight distribution and increases the sensitivity of controlling mechanisms. Where a large mass must be housed within a restricted area, Tungsten heavy alloys are the ideal material.

Tungsten heavy alloys counter balances are often used to optimize the performance of flight control surfaces, such as rudders, elevators and ailerons, with many advantages over conventional balance materials e.g. steel or lead.

Helicopter rotor blades demand perfect balance. Tungsten heavy Alloys can be utilized to compensate for any imbalances built into individual blades during the manufacturing process, such as helicopter balance.

 Today, let us learn about tungsten supply in the world.

There is plenty of tungsten in the ground. But some of the biggest tungsten deposits are different to access.

Over the last few years, sources of tungsten supply have changed dramatically. In 1986, the USSR was the largest tungsten consumer in the world. By 1992, the reformed CIS was exporting tungsten and by 1996, the CIS became the second largest tungsten supplier in the world.

Today, other main tungsten producing countries are China, Austria, Bolivia, Peru and Portugal. Whilst in the last decade, tungsten mines have closed in Australia, Brazil, Canada, France, Japan, South Korea, Sweden, Thailand and the USA.

Not only have the sources of tungsten supply altered but also have the tungsten compounds traded.
