Waterjet cutting machine uses jet of water as its key element to cut thin or thick materials.
Low on-resistance silicon carbide MOSFET targets EV drives Wolfspeed has introduced a silicon carbide MOSFET rated for 196 A, with a 900V rating and with 10 mΩ on-resistance.
Lanthanide dopants play an important role in desirable phase transformations of aluminum oxide (alumina) in order to achieve optimized physical and chemical properties.
More refractory minerals production shutdowns are anticipated amid warning of heightening pollution level around Beijing.
Two applications may be necessary for seams. After wiping it thoroughly, sand the door gently in the direction of the grain with fine sandpaper (150-180). If the door surface is rough, perform your first sanding with medium sandpaper...
In December, influenced by rising alumina prices, alumina producers in Shangdong continued to expand the production, and at the same time, a plant in Henan increased the consumption for imported bauxite.
Shares in Alumina dropped 1.6 per cent to $1.82 after the company outlined the size of the hit it will take from charges related to its AWAC joint venture's closure of an alumina refinery and bauxite mines in Suriname as well as an impairment of interest.
China appears to be experiencing regional tightness, rather than an overall alumina shortfall, with transport constraints restricting alumina deliveries from Shanxi refineries in particular.
The joint venture will also incur cash costs of $181 million over five years, of which $29 million will be incurred in 2017. Alumina's share of the costs will be limited to $12 million in 2017.
In recent years, the abrasive belt industry has obtained a series of achievements in our country.The main trends of development of abrasive belt grinding are as follows:
Indian producers have faced an increasing onslaught of cheap aluminium from overseas during the past several years, especially from the Mideast and the People’s Republic of China. Although domestic demand continues to rise, imported aluminium...
For the future alumina market, experts believe that the average price of alumina in 2017 will be better than in 2016. At least, alumina prices still have strong support before the next March. Although it can't continue to rise, but will remain high over t
India’s National Aluminium Company (Nalco) may finally be given the green light to sell alumina to private-sector rival Vedanta plc, as the Indian government has requested the state-owned firm to look into sales of the aluminium precursor to the London-ba
With benchmark alumina prices ending 2016 close to two-year highs and continuing to diverge from the LME aluminium price that contracts have traditionally been fixed to, more 2017 contracts could be linked to benchmark indices, market players have suggest
Domestic aluminium producers have asked the government to introduce minimum import price (MIP) to check cheap imports of unwrought aluminium and scrap from China and West Asia.
Compared with the explosive rise in the first two months, China’s alumina prices rose more moderately in November, and the market order structure is mainly dominated by rigid demand.
As we discussed previously, bauxite sales could be Alcoa’s growth driver after the split. Alcoa has an equity stake in Ma’aden Aluminum, which is valued at $900 million. According to Alcoa, Ma’aden operates the lowest-cost smelter globally.
Glasses, cases, bridges and more besides : sapphire finds its way into the entire spectrum of watchmaking functions. This costly yet high-performance material also boasts perfect transparency.
The researchers are developing game-changing solid-state battery technology, and have made a key advance by inserting a layer of ultra-thin aluminum oxide between lithium electrodes and a solid non-flammable ceramic electrolyte known as garnet.
