Alnico is an alloy of Aluminium, Nickel and Cobalt.It also contains Iron , Copper ,Titanium, Different metal
component constitution will form different magnet properties, application will also change accordingly.
Alnico is produced by sintered or casted technique,Its`surfaces may need machining,or to be ground for a smoother surface finish and looks brightly metallic looking. Casting means can producing AlNiCo forvariety sizes and shapes, Sintered Alnico is subsize and have very tiny tolorance but machanical performance is not good.
The most commonly used Alnico is Alnico5. There are 4 sort of cast Alnico5 plus a singlesort of sintered Alnico5 (sintered Alnico and cast Alnico have slightly different magnetic and mechanical performance). Among the permanent magnetic materials, AlNiCo have the best reversible temperature coefficient, the highest working temperature up to 500 ℃,it has the
hardest and toughest strongness.Most ALNICO Magnet grades are anisotropic (axial / vertical direction add magnetization).The others are isotropic(horizontal direction magnetized and usually have many poles on one magnet) they are weaker on magnetism but offer more options on design and properties.

According to relevant data, China's domestic market for dry aluminum fluoride, which has been in the doldrums for several months, has risen sharply, and its prices have risen sharply.
The average ex-factory price rose from 7110 yuan/ton to 7533 yuan/ton at the weekend and rose 5.95% in the week. It ranked first among all monitored chemicals.
Due to the weak demand, dry aluminum fluoride has continued to perform poorly this year. In early September of this year, the price of dry aluminum fluoride in Henan fell to 6,800 yuan/ton, and fell below the 7,000 yuan/ton mark. Since then, some enterprises in Henan and Shandong have also gradually reduced production or stopped production in order to cope with the losses caused by the sharp decline in prices of dry aluminum fluoride.
The reporter learned that the decrease in the price of dry aluminum fluoride was caused by many factors. First, the price of dry powder of fluorite No. 97 in the upstream raw materials dropped to 1,500 yuan/ton at the time, which was a drop of nearly 50% from the same period of last year. On the other hand, the weak electrolytic aluminum prices at the time and the loss of aluminum companies also depressed the purchase price of aluminum fluoride.
“The price increase of aluminum fluoride is the first to be driven by the cost of raw material price increase.†According to Zhang Li, an analyst from the fluorine chemical industry, the average price in the upper reaches of firefighting has risen from 1,625 yuan/ton in early November. As of today's 1645 yuan/ton, the price of fluorite in Shandong has risen by RMB 50-150/ton, which supports the price of aluminum fluoride. In addition, the upstream hydrofluoric acid also rebounded slightly. However, Zhang Li believes that rising costs is not the main reason for the price increase of dry aluminum fluoride.
"Recently, the National Materials Reserve Bureau has collected 160,000 tons of primary aluminum, which has increased the downstream demand. Plus, some time ago, the aluminum fluoride manufacturers have benefited from substantial capital adjustments because of this operation. At the same time, the operating rate of the manufacturers has also increased. Another analyst Yuan Ting said. She believes that the price of aluminum fluoride will continue to rise in the short term. However, this is also the only bright spot in the chemical market last week. In contrast, the second-ranked ** only rose by 1.64% last week. Of all the monitored products, only 18 products were “flying red†and 22 were down products, suggesting that the chemical market has entered “as a wholeâ€. During the winter.
"The commodities in the third week of November have been enlarged in both the fall and the fall compared with the first two weeks of November, which shows that the market chill is getting stronger," said Liu Xintian, chief analyst of the business community.
