APT domestic prices

APT domestic market this week has been warmer. According to domestic suppliers to increase the offer price of raw materials. However, compared to the previous offer appear export prices fell, export market competition, foreign customers lower prices again, the lower part of the transaction price.

Now MP for 88.5% APT offer represents a month ago before the price increase compared to 3000 yuan / ton.

Domestic market inquiries increased, but the transaction was not large-scale expansion. A manufacturer Hunan recent offer up 2,000 yuan / ton before the holiday. Sellers are more reluctant to sell due to the concentrate, it is difficult to purchase the raw materials. Although a producer Jiangxi recently received several inquiries, but no deal, waiting for prices to rise after the sale.

European antimony market supply is still tight prices

Sources said this week the European antimony ingot prices rise again, the supply is still very tight. Earlier this week, traders say prices stimulate consumption makers in the price increase is not large when to spot purchases, so now the market demand is relatively strong. Traders confirmed that the current market supply, because Asian manufacturers to push up the price as much as possible and reduced exports to Europe. Currently antimony offer late last week increased by $ 200 / ton.

European trader said a major Chinese suppliers due to higher prices and reduced exports, so the current tight supply of antimony ingot market. Makers of consumer prices rose to a higher level before adequate inventory, purchasing enthusiasm is high they are now. The trader turnover of 8 tons of cargo. He said: supply shortage caused prices upward, if this trend continues, the price will certainly rise further.

Central Europe, a trader said last week the amount of exercise alone received significantly increased consumer business had not expected such a rapid growth of prices, so they can only go up in price more before, as soon as sufficient antimony purchase in order to avoid more high purchase price. The trader stressed that although now in short supply, but many traders still timely delivery. The source also expected, if continued shortage of supply, they will offer up.

Spain’s Nanomaterials and Nanotechnology Research Center has fabricated what it claims is the first 400 mm pure tungsten carbide blank produced by a hybrid Spark Plasma Sintering-Hot Press process. The sintering technique utilises a combination of both induction and joule heating.
cinn The production of the tungsten carbide blank at the facilities of the Multifunctional Materials Development Unit marks an important milestone in the development of the Spark Plasma Sintering technology. The achievement demonstrates the possibility for industrial scale fabrication of large components via the SPS-HP process.



The Nanomaterials and Nanotechnology Research Center is a joint research centre established in 2007 by an institutional initiative of the Spanish Council for Scientific Research, the Government of the Principality of Asturias and the University of Oviedo. These three institutions contribute to the CINN with funding as well as scientific facilities and staff.
The CINN combines a high-quality and internationally competitive interdisciplinary research with scientific and technological demonstration activities and has among its objectives the creation of new technology-based companies.

As Leech Carbide marks its 50th anniversary, the Meadville-area firm is investing almost $1 million in new equipment for the second consecutive year and setting the stage for the third generation of ownership. Daniel D. Leech, the third generation of the Leech family, has been promoted to vice president of Leech Carbide and has acquired part ownership of the firm. Terms of the sale weren’t disclosed. Leech Carbide is a local tungsten carbide manufacturer started in 1965 by Daniel J. Leech, Daniel D. Leech’s grandfather.

The firm had five employees at the outset, but today has around 70 skilled workers, according to Daniel T. Leech, the current president, and owner of the firm since 1985. Daniel T. Leech is the son of Daniel J. Leech and the father of Daniel D. Leech.
The growth of tungsten carbide technology is the direct result of the need established by the tooling and machining industry and other industries for wear-resistant parts.

Tungsten carbide is a mix of tungsten and carbon and is approximately two times stiffer than steel. Cutting tools made of tungsten carbide are more abrasion resistant and can withstand higher temperatures than standard high speed steel tools.
Tungsten carbide cutting tools are used for machining through materials such as carbon steel or stainless steel. They also are used in applications where other types of material would wear away quicker such as high-quantity production runs.
Because of high demand for its products, Leech just keeps growing, according to Daniel T.



“We’ve got close to 50,000 square feet of (manufacturing) space now,” he explained. “We’ve got more than 1,000 customers worldwide and we’re making parts for everything from medical equipment to farming. We do everything from corn-planting tools to tools for Ikea furniture.” To keep up with growing demand for its products, the firm purchased almost $1 million worth of CNC manufacturing equipment in 2014 and is purchasing a similar amount of equipment this year, he said.

The Leech Carbide plant has always been located at 1061 Lamont Drive in West Mead Township, just east of Meadville, but has been expanded several times. In a 10-year period, Leech has added three times to its production and administrative facility.
“We’re a lot bigger and a lot more organized — I can remember when this plant was just a 30-(foot)-by-30-(foot) room and we only had three or four guys working,” Daniel T. said with a chuckle.

Daniel D. Leech, 36, too, said he’s seen a lot of changes in the close to two decades he’s been involved in the business.
“Today, we’ve got more CNC machinery and one guy is running three or four machines,” the younger Leech said. “We’re making parts smaller, too. Leech Carbide doesn’t see its growth slowing down any time soon.
“A lot of what we sell goes to China, but we’re seeing a lot of (manufacturing) work coming back from China as well,” Daniel T. said.

Diamond is famously the hardest naturally-occurring material on Earth, and because of this it has long been used for cutting and drilling operations. Whether the operation is downhole drilling for oil and gas, or precision shaping in an engineering workshop, the principle of any cutting is that the tool must be harder than the work piece.
Despite this, diamond hasn’t always been the preferred cutting edge. Along with its exceptional hardness come other properties that limit its usefulness as a cutting tool. Now, however, a new development from hard surfacing specialists Cutting & Wear and advanced surface coating innovator Hardide Coatings has solved many of these problems and has, in effect, created new diamonds that can work harder than the originals.



One of the challenges with diamond as a cutting medium is that its very hardness can make it brittle. Diamond is a pure form of carbon in which the atoms are arranged in a closely packed crystal lattice. In the face-centred cubic (or 'diamond lattice') crystal, each atom is bonded to four neighbours with strong covalent chemical bonds. The result is a uniquely strong crystal structure which tolerates few impurities.
As well as its exceptional strength, the structure of diamond makes it almost completely unreactive to other chemicals, with very high thermal conductivity, a very low coefficient of thermal expansion, an extremely smooth surface, and a very high refractive index. While these properties are useful, and in some cases make larger gemstone diamonds so valuable, they also make the material tricky to use in cutting tools. In particular, the smoothness of the crystal's facets and its chemical inertness means that it has great non-stick qualities. The result is that diamond has poor wettability, and does not work well with adhesives.
This becomes an issue when incorporating diamonds and diamond grit into cutting and drilling tools.

The only effective way to do this has been to encase the particles in the metal matrix, relying on the mechanical strength of the metal to hold it in place. However the thermal expansion of the metal is higher than that of diamond, meaning that its grip will loosen as temperatures rise – as they generally do during cutting operations unless care is taken to cool and lubricate the tool.
Heat presents another difficulty, causing diamond to oxidise and degrade to graphite. Although popular culture holds that 'diamonds are forever', the reality is that at temperatures above 400°C the hardest material on Earth can quickly undergo graphitisation and revert to one of the softest – graphite – especially in the presence of some metals.
Finally, while the anisotropic lattice structure of diamond is very strong, it does present fracture planes along which the crystal can shatter. Constant directional impact can cause brittle fracture in monocrystalline diamond.
