Study shows that the density of a radiation shielding material decides its penetration by gamma and x-rays. The denser the material, the more the gamma or X-ray intensity is reduced.

As we know, lead is the densest of commonly available material, which has been used to provide shielding from gamma and x-rays. However, it should be recognized that lead is not the densest element. For example, tantalum, tungsten, and thorium are higher on the density scale, but lead is readily available, easily fabricated, and cost less than these materials. Lead bricks can be purchased and arranged in various ways to shield radiation.

Compared to lead, tungsten shows much active effects on gamma and X-ray radiation protection, as its much higher density, good machinability, environmental-friendly and high hardness. It could be machined into different shapes as per different working environment and requirement. However, cost for tungsten manufacture and machining is higher than the lead material.

Tungsten market: With the recent increase of raw materials procurement Scheelite difficult, purchase price increases, tungsten powder manufacturers offer by this week to support and maintain strong, and the high price range is slightly higher, the price of tungsten powder or concentrated in the mainstream 205-210 yuan / kg. End of the market demand is still busy, so late to continue sharply upward blocked, before the Spring Festival, or stabilization of the main powder prices.

Molybdenum market: copper, nickel and other metals group fell peripheral, so molybdenum market fears increase, downstream active buying scarce, steel mills have negative procurement, market supply and demand fundamentals did not improve, resulting in molybdenum market dip cycles. Short-term market is expected to continue to weaken.

Overseas demand remained sluggish tungsten City, only small-scale transactions, tungsten iron prices stable Europe was down, is expected before the Spring Festival, or hard tungsten overseas rose. It is understood that the Vietnamese sun star tungsten industry started trial production of sodium tungstate.

The latest week MB Rotterdam ferrotungsten 33-34 USD / kg of tungsten, the average price fell $ 0.5, paratungstate Eurodollar 270-315 / metric ton, the average price fell $ 2.5.

This week tungsten powder smelter home offer a slight increase, the range quoted slightly raised high, and gradually approaching the range of high turnover. Analysis predicts end of the market demand is still busy, so late to continue sharply upward blocked, before the Spring Festival, or stabilization of the main powder prices.

The powder products prices for two main reasons: on the one hand raw tungsten concentrate market upward, raising the cost of supporting tungsten powder prices, also contributed to the increase downstream manufacturers purchase intentions; on the other hand, the end of this week, will soon be home tungsten powder smelter shutdown maintenance, single or downstream users continued under the new orders in the near future, the recent increase in actual demand.

January 13, Commerce Department of Treaty and Law Department official on the Chinese Government to abolish export quotas for rare earths and other management issued a statement.

Recently, the Chinese government abolished for rare earths, tungsten, molybdenum and other products of export quota management, aroused great concern. Commerce Department of Treaty and Law Department official has issued a statement that the rare earths, tungsten, molybdenum and other products of export quotas cancellation product management reform is in line with the domestic rare earth resources such as class I, at the same time, considering the implementation of a WTO ruling related to the conduct of policy adjustments.

Tungsten market: businesses generally optimistic about the market after the tungsten ore, tungsten ore cargo hold very strong emotional reluctant to sell, market purchases more difficult, tentative inquiry compelled to raise, stabilize the main tungsten products, some manufacturers offer even with the slight increase in raw material prices upward while. Recent market conditions continued maintenance of stability of tungsten scrap, scrap tungsten steel cargo operators continued reluctance to sell not waste tungsten grinding away material is difficult to hold stocks of goods, is expected to total tungsten market volume was light.

With respect to the recent fluctuations in the raw materials market, the recent market conditions continued maintenance of stability scrap tungsten, tungsten steel scrap cargo operators continued reluctance to sell not waste tungsten grinding away material is difficult to hold stocks of goods, the overall market volume was light.

It is understood the import of waste tungsten inserts the current market price excluding tax mainstream 154-159 yuan / kg, scrap tungsten blade domestic price excluding tax mainstream 147-149 yuan / kg, scrap tungsten drill 155-160 yuan / kg, 70 degrees above tungsten grinding waste material is still near 1.35 yuan / kWh, almost no change compared to the price of a half months ago.

With respect to the recent fluctuations of raw materials markets, businesses generally optimistic after tungsten ore market, tungsten ore cargo hold very strong emotional reluctant to sell, market purchases more difficult, tentative inquiry compelled to raise, stabilize for tungsten-based products Lord, some manufacturers offer even with a slight increase in raw material prices and upward.

Macro level, the 12 western provinces generous layout CCCC, a total investment of over 600 billion this year; last year's investment growth or hit 13-year low, multi-year plan to expand investment in the province to open; Bank lowered global economic growth is expected.

Tungsten market: Inquiry increased raw material of tungsten ore, tungsten ore prices firm and was up slightly, but holding business sellers, spot market transactions stalemate, tungsten ore market in mid-January or continued strong run. Ferrotungsten market demand continues to slump, the market temporarily steady run, newly signed smelter single hard, take the goods difficult. Years ago, the market demand is expected to iron or tungsten hard to break.

This week ferrotungsten market demand continues to slump, the market temporarily steady run, newly signed smelter single hard, take the goods difficult. Market demand is expected ago ferrotungsten or difficult to break, mainly due to: the Spring Festival approaching, the downstream steel industry needs less equipment downtime smelter also began to leave home, tungsten, iron market inquiry less turnover situation is not optimistic. It is understood that the cash price concentrated 15 yuan / ton or less, redemption price at 152,000 yuan / ton.

Tungsten iron prices are expected to decline year may not: on the one hand due to raw material price increases, the cost of support, and cargo operators reluctant to sell raw materials, raw material procurement more difficult; on the other hand this tungsten iron smelters home inventory has been strictly controlled, tungsten iron smelter currently home inventory is not large, open next year in procurement of raw materials more difficult, is estimated to have a new multi-March tungsten produced iron products, tungsten, iron smelters therefore not possible at home before selling cheap tungsten iron.
