Sodium tungstate market demand remains in the doldrums, with tungsten Association guidance price declines, Minmetals has not buy in large quantities, this week the sodium tungstate inquiry lowered again, although the smelting manufacturers cut and dimension stability quote, but the actual transactions is still slightly lower. According to the current understanding of 96 sodium tungstate mainstream cash prices in the 12.4-12.5 yuan / ton near, part processing or slightly lower.

Ammonium paratungstate market continued to slump, price stability test, the cash price of the mainstream in 16.2-16.3 yuan / ton, compared with last week, down 1000 yuan / ton. Analysis of the causes of the ammonium paratungstate market down: one is the terminal consumption ability is poor, resulting in ammonium paratungstate downstream demand is difficult to release, ammonium paratungstate market demand not flourishing; two is the latest August tungsten Association guidance prices down again, the business mentality of weakness, high price decline. Is expected in the short term the ammonium paratungstate price or in the 16-16.3 yuan / ton.

Tungsten market: yesterday Minmetals guidance prices flat, Ganzhou tungsten co guidance prices down slightly as expected, 65 degree black tungsten from 110000 to 107000, closer to the actual market price 105000, because the two big institutions offer the disagreement continued weak demand downstream, Shang Jiamu, before the main wait-and-see, late funds hold the goods business shipment or slightly increased, expected short-term tungsten price stability and fall.

Yesterday the Minmetals Nonferrous and Ganzhou tungsten co published guidance price is different, Minmetals flat 65 degree black tungsten concentrate bid to 110000 yuan / ton, Ganzhou tungsten co down 3000 to 107000 yuan / ton, the two price is still higher than the actual price, in this price spot market sale does not ship. It is understood, now a 65 degree black tungsten concentrate 105000 yuan / ton are difficult to sell, 65 degree white tungsten concentrate even now 103000 yuan / ton low price.

The two institutions offer the differences, continued weak downstream demand, businesses at present mainly wait-and-see, late funds tense shippers shipping intention or slightly increased, the short term price of the tungsten vulnerable, there is still risk small fell.

Minmetals announced yesterday August guidance prices flat with July, but Ganzhou tungsten co downregulated, tungsten, mentality also weakened, waste tungsten market wait-and-see atmosphere thickening, merchants offer to steady, the market price is still more resources. Ammonium paratungstate prices fell, tungsten concentrate not yet noticeable drop.

Waste tungsten market mainstream remains stable. At present, the waste tungsten bit not including tax price of mainstream is still concentrated in the 188-190 yuan /kg, domestic waste tungsten blade 169-171 yuan /kg, imports of scrap tungsten blade 179-181 yuan /kg, waste tungsten grinding material 30-40 traders purchase price concentrated in the 1.45-1.5 yuan / degrees, 50-70 degrees concentrated in the 1.55-1.7 yuan / degrees, 70 degrees or more concentrated in the 1.7-1.75 yuan / degree, expected short-term waste tungsten market are weakening running stability of.

Hardide Coatings has supplied its Hardide T nano-structured tungsten carbide coating for a new range of trunnion-mounted ball valves for the UK energy sector.

The ‘Phase’ range includes numerous variations of soft and metal seated side entry ball valves, used for the safe isolation of pipeline production and process equipment. These valves are often used in erosive operating environments, so the new valve required a durable protective tungsten carbide coating. The Phase range comes in both metal to metal and soft seated options which posed additional considerations.Metal to metal seated valves often suffer wear by erosion when there is particulate in the process fluid. Most ball valves are soft seated, but wear can also cause scratches and resultant leakage.

Heap & Partners selected Hardide-T for use in the range, particularly in the smaller diameter valves, for several reasons, including the inherent hardness of Hardide-T, at 1100 to 1600 Hv with a typical tungsten carbide coating thickness of 50 microns. Hardide-T is produced in a gas-phase CVD (chemical vapour deposition) process.

“The Hardide coating achieved excellent results, meeting all the required leakage rates and delivering consistent results on various substrates,” said Peter Burnett, business development manager at Heap & Partners. “We also chose to partner with Hardide Coatings as we worked with the team previously on a project in the nuclear sector to tackle a corrosion issue and carry out re-engineering of valves.”

Corrosion resistance

Heap & Partners has now utilised Hardide-T on many ball valve applications for both oil and gas and nuclear clients. There have been no wear issues since employing the tungsten carbide coating and it has provided protection from erosion. In some cases the Hardide coating has also improved the corrosion resistance of the base material.

Tungsten market: tungsten, rich atmosphere, businessmen wait tomorrow upcoming guide price. Tungsten smelting factories on-demand procurement of raw materials. Weak demand, only a small amount of the transaction, the transaction has tungsten atmosphere more deserted, at home and abroad for demand weakness, but compared to other products in China this summer for price decline is very small, the current waste tungsten prices relatively stable, shippers pricing power is insufficient, the market low price resources still more mainstream, expected short-term market stabilization.

Although the overseas holidays, at home and abroad for the demand is weak, but compared to other products in China this summer for price decline is very small, the cumulative decline less than 2000 yuan / ton. The main factors for the summer market is expected to support stability is: domestic smelting ferrotungsten manufacturers operating rate is very low, even lower than the 50% at present, supply reduction, the downward price blocked ferrotungsten.

Today's price guide forthcoming, tungsten market unusually quiet, many businesses see, for maintaining stability of the market, at present 70 for mainstream price for 17.2-17.6 yuan / ton, 80 for mainstream price in the vicinity of 185000.

At present, the waste tungsten prices relatively stable, shippers pricing power is insufficient, the market price is still more resources. In August the tungsten concentrate guidance price will be announced, the market strong wait-and-see atmosphere, expected short-term waste tungsten market continue to stabilise.

Waste tungsten grinding material 30-40 traders purchase price concentrated in the 1.45-1.5 yuan / degrees, 50-70 degrees concentrated in the 1.55-1.7 yuan / degrees, 70 degrees or more concentrated in the 1.7-1.75 yuan / degree. Waste tungsten bit not including tax price of mainstream is still concentrated in the 188-190 yuan /kg, domestic waste tungsten blade 169-171 yuan /kg, imports of scrap tungsten blade 179-181 yuan /kg, the price tends to be low, the business quoted price is still strong. Waste wire drawing mould quotation still more confusion, some high priced up to 185 yuan /kg, but also 179 yuan /kg low pricing, business mentality is different, so the price gap.

Tungsten market: tungsten market continued trading was light, it is understood in tungsten concentrate prices hovering at 105000 yuan / ton near the light, the actual transaction. The business operation of enthusiasm is extremely low, wait for a price guide published, having more clearly and make sure. Tungsten steel market temporarily stabilized wait-and-see, clinch a deal valence slightly to low. But the price is still relatively strong, the market has no obvious decline. Affected by the downturn in demand in August is expected to drag on, guiding price or continue a small drop of potential.

Tungsten steel scrap market temporarily stabilized wait-and-see, clinch a deal valence slightly to low. But the price is still relatively strong, the market has no obvious decline. Waste wire drawing mould quotation is relatively confusing, some high priced up to 185 yuan /kg, but also 179 yuan /kg low price, not a business mentality, widening price gap. At present, the waste tungsten bit not including tax price of mainstream is still concentrated in the 188-190 yuan /kg, domestic waste tungsten blade 169-171 yuan /kg, imports of scrap tungsten blade 179-181 yuan /kg.

At present, the waste tungsten grinding material 30-40 traders purchase price concentrated in the 1.45-1.5 yuan / degrees, 50-70 degrees concentrated in the 1.55-1.7 yuan / degrees, 70 degrees or more concentrated in the 1.7-1.75 yuan / degree. The market price of resources is still more, the market is not strong, but the early market funds pressure small, price low willingness of shippers. Expected short-term waste tungsten market steady operation.

Tungsten went abroad. 1 evening MB Rotterdam quotation for 40.5-41 dollars / kg tungsten, down 1 U.S. dollars; ammonium paratungstate European price 360-370 USD / ton, Hongkong price 361-370 USD / ton, to continue the steady. The European market is still in the summer season, the downstream demand is very low, the overall turnover deserted, expected short-term overseas tungsten continued weakening operation.
