Tungsten market: With the summer break into foreign, overseas orders decrease, lower APT market demand, manufacturers received fewer orders, transaction difficulties, sodium tungstate market overall smooth and quiet operation, the factory operating rate is low, difficult to sell at high prices, cheap shipping even inversion phenomenon, more and more manufacturers to suspend production of sodium tungstate, watching the market. Tungsten increasingly sluggish demand, prices steady weakening, the market volume was light, wait and see mood strong, especially traders will ship very low, both hold stocks sidelines waiting for the market outlook rose to a certain peak, is expected to have significant short-term gains or difficult.

Tungsten prices steady Ming kicked upstairs. Currently the mainstream price of tungsten powder and tungsten carbide market concentration in the 258-260 yuan / kg, down about 2 yuan / kg, individual businesses 255 yuan / kg also cheap shipping, but most businesses are still reluctant to cut prices, steady still waiting to see the majority.

Steel market price at 285 yuan tungsten concentrate / kg, high-purity tungsten 310 yuan / kg, down about 5 yuan / kg. 99.98% of the reference price of tungsten military 480,000 yuan / ton. Since the powder prices continue to decline, prices of manufactured goods would be difficult to continue to firm, businesses offer had to be reduced. Tungsten prices or expected short-term transient stability sidelines.

Tungsten market: the traditional off-season approaching, the market demand is more sluggish, tungsten concentrate market turnover continued light, mine take the goods properly and ore purchase price is higher, the relative cost of mining, now the ore price is still no inversion phenomenon, there certain profit margins, some businesses in order to ease the financial pressure, shipping is also relatively positive. APT, tungsten, iron, tungsten manufacturers received exercise alone has decreased, the price adjustment underpowered, although quoted stabilize, but the actual transaction Yindie material tungsten City this week, the market mainstream steady weakening.

Tungsten concentrate market turnover continued light, mine take the goods properly and ore purchase price is higher, the relative cost of mining, now the ore price inversion phenomenon still does not appear, there is a certain profit margin, some businesses in order to ease the financial pressure, shipping also relatively positive. It is understood that 55 degrees is not tax price of tungsten ore hair is 1.4 yuan / degrees, about 60 degrees above 1.42 yuan / kWh.

Strong ore market, in terms of tungsten concentrate smelter home increased raw material costs, profit margins are low tungsten concentrate shipments, partially or even upside down, and therefore reluctant to sell their home smelter darker mood, quotes enthusiasm is not high, on the sidelines more.

Traders, buyers reluctant to purchase high-priced, low-cost seller was unwilling to take the goods, cash has been stuck, turnover continued stalemate, the operation dilemma, traders hold stocks and more recently watching the market for gold, nine silver ten have expectations.

Tungsten market: Due to continued weakness in demand, low prices, some of the tungsten iron smelters home suspend production, planning and other market conditions improved then. Medium and large tungsten iron smelter home remains started purchasing much for tungsten iron, large manufacturers inventory pressures, cautious traders operate. Scheelite mainstream market to stabilize, but demand remained weak, the specific transaction Yindie phenomenon, the relative decline in the actual transaction 500-1000 yuan / ton, high quotations have also been reduced, expected post-market or down slightly.

Due to continued weakness in demand, low prices, some of the tungsten iron smelters home suspend production, planning and other market conditions improved then. But in a large tungsten iron smelter remains home to start the downstream steel smelting, machinery industry, tungsten, iron recent purchases for small, large manufacturers inventory pressures, cautious traders operate.

Close in July and August the traditional off-season, more sluggish market demand, APT, tungsten, iron, and other manufacturers received fewer inquiries single smelter home price adjustment underpowered, although manufacturers outside offer stabilize, but the actual transaction Yindie and cash payment difficulties , how much cash to pay the current transaction.

Tungsten market: Scheelite conditions stabilize, the market continued oversupply, applying downward pressure on prices, turnover deadlocked. Ferrotungsten continued weak market demand, volume decreased slightly. APT manufacturers are not enthusiastic to sales quotas, tungsten scrap market weakness stability maintenance, poor demand and price adjustment due to lack of motivation, most traders tungsten scrap funding constraints, operational dilemmas, some traders a small receipt, quickly take the goods, Boli more sales. Due to high-priced stock, and businesses continue watching the market. Short-term market or are expected to continue to stabilize the tungsten scrap.

Maintenance of stability-oriented tungsten market today, Scheelite offer flat, not market demand continues to improve, the transaction price is hovering at a low position, currently traded in 110,000 yuan / ton. Lack of internal demand is expected to support short-term, tungsten concentrate prices up will be blocked, July ore price or less steady decline.

However, both the traditional miners of gold, nine silver ten have great expectations that this year there is a tungsten City certainly gained momentum, most likely in the fourth quarter, thus holding cargo ship will generally not high, wait and see mood strong. Meanwhile, investors also believe that the turning point may have ushered in the late tungsten City, concerns more hot money into the city late tungsten or increased.

Notable amid the vast array of information and knowledge shared at the 13th Electronic Circuits World Convention in Nuremberg, Germany, was the highly-informative session on advances in drilling and routing, with a focus on the technology of tungsten carbide cutting tools. The session was introduced and moderated by EIPC Technical Director Michael Weinhold.

Growth in applications of high-power LEDs had created an increasing demand for substrates with high thermal conductivity, and resulted in the development of a wide range of insulated metal substrates heavily loaded with ceramic fillers in the dielectric. Consequently, the dielectric layer of these composite laminates tended to be very abrasive, causing rapid wear of conventional tungsten carbide routing cutters. Johann Schmidt of CGT GmbH discussed how diamond coated tools could significantly increase dimensional accuracy and reduce production cost.

Schmidt described a proprietary process for diamond coating of tungsten carbide drills and routers, based on hot-filament chemical vapour deposition. A particular feature of this proprietary coating was that it was built up as a multilayered combination of different crystalline and nano-crystalline layers. Typical coating thickness was 12 microns, although this could be varied depending on tool geometry and diameter. The multilayered structure gave the benefit of resistance to crack propagation, a major limitation of single-layer coatings, and a very smooth surface with low friction and excellent chip-removal characteristics. Hardness of the coating was approximately 9000VPN, compared with about 2100VPN for standard tungsten carbide grades, and coated tools could be used at higher feeds and speeds.

Schmidt showed many comparative examples: On a typical IMS substrate, routing feed could be increased from 4 mm per second to 15mm per second with tool life extended from 7.5 metres to 60 metres. And a coated drill could complete 1,000 hits with no clogging, whereas a conventional drill was clogged with aluminium swarf after only 150 hits.

Diamond-coated tools offered greater dimensional accuracy and cost and productivity benefits from increased production speeds and significantly improved tool life resulting in less machine down-time for tool changing. Clearly, even with the most advanced cutter technology, good tool management, machine maintenance and operating discipline were essential, with minimal spindle run-out, rigid fixturing of the work and powerful vacuum extraction if the best results were to be realised. Some applications, such as using a 2-flute end-mill on IMS, benefited from wet lubrication.
