国内钨价呈现弱势整理行情

2018-07-05views（0）转发文章

国内钨价呈现弱势整理行情，大企长单价格下调加剧市场偏空气氛，终端用户采购积极性较弱，贸易商受传统淡季效应以及供应增加忧虑影响，避险出货情绪增强。不过由于冶炼厂复工后的产能释放仍需要时间调节，厂家报价调整幅度相对保守，场内观望情绪浓郁，成交量稀少。

钨精矿市场上，矿山企业持续受到环保影响对外供应量有限，加之下游冶炼厂陆续复工，对原料的消耗能力预期将有所恢复，因此持货商在宏观经济动荡以及需求面利空背景下暂时稳价出货，市场观望氛围浓厚，成交冷清。

APT市场上，经历了近月的高位僵持行情之后，在环保督察暂告段落以及泛亚等非法吸收公众存款案开庭审理背景下，业者对后市APT供需预期并不乐观，而大企长单回调加剧市场偏空气氛，APT价格趋于阴跌整理，厂商因目前库存仍处低位，心态相对理性，观望机构预测均价，以及其他上市企业长单报价。
Tungsten stock market today

2018-07-03views（0）other

Tungsten stock market today: week domestic tungsten price continued stalemate, with environmental protection supervision policy to the paragraph, APT smelter production will start back in succession, the merchants of afternoon is expected to appear obvious differences, some think afternoon tungsten raw material requirements or will increase, and APT to raw material of downstream products due to raw material procurement, in which exploration difficulty and cost reduction and appear callback trend; Some argue that environmental policies will only increase, that the remaining temperature of the current inspection will remain, and that the supply side and the cost side will continue to support the tungsten industry.

Money problems the market at present is still not completely recede, loose traders mentality affect the price of tungsten in whole weakened the channel, tungsten products in early shipment is slow, the market marketing deadlock, focus on a new round of institutions and large enterprise attitude direction.
Domestic tungsten price constant consolidation

2018-06-26views（0）other

Domestic tungsten price constant consolidation, end surface of supply and demand and financing area there are more uncertainty factors, influence industry market outlook is expected to diverge, lack of power, the current price level to adjust the market overall marketing talks deadlock, trading volume.

Tungsten concentrates on the market, July downstream smelter production expected to strengthen, drive the business to afternoon factories consume raw material capacity optimistic expectations, but some traders financing area confined in late shipment willingness, make the mine's price remains difficult, plus a leading producer of hunan, jiangxi and other tax subsidies to expire, market delivery harder, so the price of tungsten concentrate in the short term is still confined consolidation is given priority to.

APT market, although environmental factors on the cost side and supply side has significant support role, but the factory production expected affect the market spot positive effect of resource is limited, and the downstream demand is difficult to have a positive change, afternoon imbalance between supply and demand risk forbidding that industry is not optimistic to APT price expectations in the third quarter, a recent manufacturers still spot is not much to maintain smooth quotation for hands.

Tungsten powder on the market, the back-end product under the background of weak demand, raw material loose end trend positive factors, costs supporting role gradually fade, the traditional consumption off-season along with indication of supply and demand of hesitation, the more recent alloys and products downstream enterprises with the enthusiasm is low, weak double of supply and demand, market as a whole marketing heat light, price of tungsten powder with consolidation.
New boride tungsten superhard materials may replace tungsten carbide in the drilling industry

2018-06-21views（0）original

A team of international scientists has reported on a new type of super-hard material recently, a compound based on tungsten boride, that can be used in drilling, mechanical manufacturing and other fields. It is proved that the new type of tungsten boride has better performance than the hard tungsten carbide cobalt composite and artificial diamond materials which are widely used at present.
Superhard materials are widely used in drilling, machinery manufacturing, metal processing, defense industry, medicine and other fields. Diamonds, while having the highest hardness, are a relatively rare and expensive material, and even artificial diamonds can be prohibitively expensive for many applications. So, for the past 80 years, its competitor, the stellite carbide drill, has maintained its dominant position in the market with unparalleled cost performance.
Tungsten boride is a black or gray hexahedral crystalline powder with high hardness and is often used as a wear-resistant coating and semiconductor film for wear-resistant parts. Due to the difficulty in synthesis, there have been few reports and applications of tungsten boride at home and abroad.
Tungsten carbide materials have been used for decades to make drill bits, including drill bits, including perforators, a drilling tool similar to a piercing bullet. These rigid materials require either high pressure synthesis or much lower fracture toughness. In short, they need at least two hard indicators, namely hardness and toughness.
As is known to all, hard and tough is mutual restriction of the two inter-opposite parameters in metal, low hardness, high tenacity, brittle material is easy broken, therefore, is to find a balance of two parameters is scientists over the years dedicated to research object, scientists use USPEX WB5 evolution algorithm is a kind of new material, the material can be under ordinary conditions of synthesis, and can successfully make the drill bit in two the most important parameters - forming balance between hardness and fracture toughness. Compared with tungsten carbide cobalt drill, tungsten boride is 50% higher and 20% lower respectively. New materials are previously unknown compounds and are readily available under normal conditions. The new material is currently being tested in a large Russian project and is expected to be a new material for drilling applications.
Interestingly, the new material discovered by the team of scientists was confirmed by the simulation synthesis of supercomputer systems. They have tried a lot of materials before and fed them into computer systems to predict and calculate their performance. The new substance was eventually discovered in a sea of change. Anyhow "tungsten boron system has been the subject of many experimental and theoretical study, but they are newly discovered this tungsten boron compounds until now has not been found, this is really surprising, it is conditional and dominated nearly a century of tungsten carbide cobalt alloy material competition?
Tungsten halogen lamp is banned by Eco-design Working Plan

2018-05-31views（0）original

The move follows a proposal by the European Union to ban tungsten halogen lamps and compact fluorescent lamps as light sources by 2020 under its new eco-design Working Plan. This has been protested jointly by theaters and Lighting designers, and the Lighting designers association has launched a campaign called Save Stage Lighting to fight the proposal.

The association of lighting designers has written a petition to the European Union's energy agency seeking immunity from the legislation for entertainment lighting, such as theaters. "We strongly urge professional entertainment lighting equipment and light bulbs to be exempted from these proposed regulations and any future legislation that may directly affect the use and availability of the equipment."

The eu proposal, they said, would deal a direct and even overwhelming and devastating blow to theaters, stadiums and other venues across Europe, as well as to the entertainment industry and European culture. Under the proposal, the minimum efficiency requirements for all light source 85 lumens per watt, one of the biggest standby power of 0.5 watts, including high quality LED lighting equipment to enter the market in recent years, would be banned.

This means that almost all European venue infrastructure and inventory needs an overhaul, most of the theatre, including theater, small theater, amateur theater, universities, schools, clubs, bars, village hall, etc. Most of the lighting lamps and lanterns will be out of date, and for several decades only need some regular maintenance or replacement new bulb fixtures, will become a pile of scrap metal and small pieces.

If the proposal is approved, the British theatre alone could face losses of about 1 billion pounds (8.55 billion yuan), according to calculations by people involved. In response, the London theatre association and the British theatre association issued a joint statement saying that "the draft new EU ecological design legislation will seriously affect existing stage lighting equipment". "These changes will have a significant impact on the way the show is lit and will have a significant impact on performing arts institutions and other venues, some of which may have to be shut down."

Save Stage Lighting sports participants said that we are not against to protect the precious resources, but the Lighting is not a big energy users: Lighting show in a relatively short period of time only, and show relatively few times a week, the lamps and lanterns is rarely at the same time, it will light up. Studies in recent years have shown that stage lighting typically accounts for less than 5 percent of a theater's total energy consumption.

Before it is worth noting that the Save Stage Lighting sports related personnel has met with the European commission, and shall submit to the commission the immunity for entertainment Lighting, theatre or is expected to receive immunity.
