Its source ore, alum, has been known since the 5th century BCE; it was extensively used by the ancients for dyeing and city defense; the former usage would only be more important in medieval Europe. Scientists of the Renaissance figured alum was a salt of a new earth; during the Age of the Enlightenment, it was established that the earth was an oxide of a new metal. Discovery of this new metal was convincingly announced in 1825 by Danish physicist Hans Christian Ørsted; his work would be greatly extended on by German chemist Friedrich Wöhler. Pure aluminium metal was very difficult to refine and thus very rare. After its discovery, its price exceeded that of gold; the rarity of aluminium would only be reduced after the first industrial production was initiated by French chemist Henri Étienne Sainte-Claire Deville in 1856. Aluminium became, however, much more available to the general public with the Hall–Héroult process developed by French engineer Paul Héroult and American engineer Charles Martin Hall in 1886 and the Bayer process developed by Austrian chemist Carl Joseph Bayer in 1889. These methods have been used for aluminium production up to the present day. After these methods were applied for mass production of aluminium, the metal has been extensively used in industry and everyday lives. Aluminium has been used for aviation, architecture, and packaging among others. Its production grew exponentially in the 20th century and aluminium became an exchange commodity in the 1970s. In 1900, the production was 6,800 metric tons; in 2015, it was 57,500,000 tons.   WHAT IS ALUMINIUM? Posted by: aluhm - 01-04-2018, 03:16 AM - Forum: Knowledge & Technique - No Replies Aluminium is a silvery-white metal, the 13 element in the periodic table. One surprising fact about aluminium is that it's the most widespread metal on Earth, making up more than 8% of the Earth's core mass. It's also the third most common chemical element on our planet after oxygen and silicon. At the same time, because it easily binds with other elements, pure aluminium does not occur in nature. This is the reason that people learned about it relatively recently. Formally aluminium was produced for the first time in 1824 and it took people another fifty years to learn to produce it on an industrial scale. The most common form of aluminium found in nature is aluminium sulphates. These are minerals that combine two sulphuric acids: one based on an alkaline metal (lithium, sodium, potassium rubidium or caesium) and one based on a metal from the third group of the periodic table, primarily aluminium. Aluminium sulphates are used to this day to clean water, for cooking, in medicine, in cosmetology, in the chemical industry and in other sectors. By the way, aluminium got its name from aluminium sulphates which in Latin were called alumen. Corundum  Such precious stones as ruby, sapphire, aquamarine and emerald are also aluminium minerals. The first two are corundum, i.e. aluminium oxide (Al2O3) in crystal form. It's naturally transparent and in terms of strength it's only second to diamonds. Sapphire is used in bullet proof glass, aeroplane windows, scratch resistant smartphone screens. In the meantime one of the less precious corundum minerals, emery, is used as an abrasive, for example in sand cloth. Today we know about almost 300 various aluminium compounds and minerals containing aluminium, from feldspar, a key source mineral on Earth, to ruby, sapphire and emerald, which are far less common.  Humphry Davy. The British physicist and chemist Sir Humphry Davy was the first to obtain a new chemical element using electrolysis: he was able to obtain boron from boric acid. He went on to use electrolysis to isolate six more previously unknown metals: potassium, sodium, barium, calcium, magnesium and strontium. It was Davy who proved the existence of aluminium, the metal found in alumina, and gave it its name. But regardless of how common aluminium may be, it may have remained hidden forever if it hadn't been for electricity. The discovery of aluminium was made possible when scientists were able to use electricity to break down chemical compounds into their elements. In the 19 century the Danish physicist Christian Oersted used electrolysis to obtain aluminium. Electrolysis or electrolytic reduction is the process that is used to produce aluminium today as well. Another rather common mineral, bauxite, is used today as the primary raw material in aluminium production. Bauxite is a clay mineral comprising various modifications of aluminium hydroxide mixed with iron, silicon, titanium, sulphur, gallium, chromium, vanadium oxides, as well as sulphuric calcium, iron and magnesium carbonates. In other words, your typical bauxite contains almost half the periodic table. By the way, because of the texture of bauxite about a hundred years ago aluminium was often referred to rather poetically as silver obtained from clay. On the average 4-5 tonnes of bauxite are needed to produce 1 tonne of aluminium. Bauxites  Bauxites were discovered in 1821 by geologist Pierre Berthier in Southern France. The new minerals were named after the area they were discovered in: Les Baux. About 90% of the global supply of bauxites is found in tropical and subtropical areas such as Guinea, Australia, Vietnam, Brazil, India and Jamaica. In the first stage of aluminium production bauxite is processed into alumina, or aluminium oxide Al2O3. Alumina looks like white powder and it is then processed into aluminium at aluminium smelters using electrolytic reduction. Aluminium production requires huge amounts of electricity, about 15 MWH per tonne of output. That's approximately as much as a 100-apartment block consumes in a month. So the best site for an aluminium smelter is next to a powerful, preferably renewable, energy source. Hydroelectric power plants are the best option as they are the most powerful 'green' energy sources available today.   Marine aluminum services the national market Posted by: aluhm - 01-04-2018, 03:12 AM - Forum: Knowledge & Technique - No Replies Aluminum plate is the main products of the shipbuilding industry. Planking higher performance requirements for materials, especially as a new alternative materials - aluminum alloy materials, Marine aluminum plate to meet the requirements of thickness, shape, and strength, in durability and corrosion resistance, etc., also should comply with the class material license certification.

Although customers have a lot of choices when they buy aluminum plate, they are also annoyed at the increasing risks due to the strength of the aluminum sheet supplier is uneven and a lot of dishonest aluminum manufacturer to disrupt, especially a lot of bulk purchase higher request on the strength of the aluminum sheet supplier, choosing high quality aluminum suppliers becomes a necessary problem. In order to improve the customer identification ability, haomei aluminum experts help customers from the perspective of the following screening aluminum manufacturers. 1, the size and strength of the aluminum sheet supplier it is important to choose a certain number of alternative aluminum plate supplier before Customers choose and buy aluminum plate and then compare to the manufacturer of the scale and comprehensive strength, due to the special reasons of the industry, aluminum manufacturer of large scale and strength, in raw materials procurement, process innovation, and processing quality is better, and a lot of small factory due to too small all have no advantages in various aspects, and then the sale price is not higher than the market too much, so only the lower requirements on quality and service ,this will lead to increase the risk of buying customers, it is recommended that the customer must choose strength strong business cooperation in the industry. You’d better have an investigation on your own.   2, aluminum sheet supplier quotations and delivery time When customers in the communication with the aluminum supplier must determine the quotation and cycle of each other, whether it is in stock, delivery time, many small factory make guarantee on price and cycle at random in order to undertake a client,, so the customer must be put on the skin bright eyes, also cannot careless on the core issues, for the other side of the guarantee must carefully identifying, for obvious at a low price and is unlikely to complete processing cycle must find out.. About the price of aluminum plate calculation method is introduced in the previous article also carried out, the client may view. 3, understand the aluminum supplier reputation and after-sales After aluminum suppliers selected, but also to understand the word of mouth, customer query before cooperation. In addition to the supplier's situation must also detailed understanding, such as aluminum products processing, product return process, etc.   The introduction of cellular aluminum plate Posted by: haomeialu - 01-04-2018, 03:05 AM - Forum: Knowledge & Technique - Replies (2) Honeycomb aluminum plate is made up of aluminum honeycomb, aluminum alloy plate on the back and the middle compounded paste; Honeycomb aluminum plate is whole aluminum products with light weight and high strength, easy to recycle, conforms to the spirit of the contemporary environmental protection.Honeycomb aluminum plate used in the construction, can bear the wind pressure strength requirement of special region supertall buildings, can meet the demand of building a bigger frame, and has the very good flatness.
