Alumiinin ja alumiiniseosten kehityshistoria

Source of aluminum

Aluminum is named after the Latin word “alumen”, which means “bitter earth” or “alum”. Nimen ehdotti ensimmäisenä ruotsalainen kemisti Jons Jakob Berzelius noin 1825 kuvaamaan tämän metallioksidin ominaisuuksia. Later, when Hans Christian Ersted successfully extracted the metal aluminum, he suggested naming the newly discovered metal “aluminium”, a name that was widely accepted in Britain and other countries.

Alumiinimalmi

Kuitenkin, in the United States, people preferred to call it “aluminum”, and this spelling eventually became widely used in the United States and Canada and became the international standard. Siksi, today we usually call it “aluminum” in English.

sisään 1746, German scientist Porter used alum to prepare alumina.

sisään 1807, the British master and apprentice David failed to electrolyze molten alumina to obtain metallic aluminum.

sisään 1809, David named the envisioned metal Alumium, which was later changed to Aluminum.

sisään 1825, Danish scientist Osler used potassium to reduce aluminum oxide to obtain a small amount of metallic aluminum.

Alum

sisään 1854, French scientist Deville used sodium to reduce NaALCL4 complex salt, and built a factory to produce some aluminum helmets, tableware and toys, which were expensive and equivalent to gold.

sisään 1886, American inventor Charles Martin Hall and French engineer Paul-Louis Taubet independently invented a method for electrolytic extraction of pure aluminum at almost the same time, called the “Hall-Tauppet process”. This greatly reduces the production cost of aluminum and makes aluminum a widely used metal.

sisään 1888, the first electrolytic aluminum plant was established in Pittsburgh, USA, and aluminum production entered a new stage.

The invention of the Bayer process to produce alumina from bauxite in 1888 and the advancement of direct current electrolysis technology laid the foundation for the development of aluminum production on an industrial scale.

By the end of the 19th century, the production cost of aluminum began to decline significantly, and aluminum itself had become a common and commonly used metal.

In the early 20th century, in addition to daily necessities, aluminum was mainly used in the transportation industry.

sisään 1901, aluminum plates were used to manufacture automobile bodies.

sisään 1903, Alcoa supplied aluminum parts to the Wright brothers to build small airplanes. Automobile engines began to use aluminum alloy castings, and the shipbuilding industry also began to use aluminum alloy thick plates, profiles and castings. With the increase in aluminum production and the advancement of science and technology, aluminum has been used in other industrial sectors (such as medical equipment, aluminum printing plates and steelmaking). The use of deoxidizers, packaging containers, jne.) is also becoming more and more widespread, which has greatly stimulated the development of the aluminum industry.

German A. Wilm invented duralumin alloy (Al-Cu-Mg alloy) sisä- 1906, which tripled the strength of aluminum and was widely used in aircraft manufacturing and other arms industries during World War I. Since then, aluminum alloys with different compositions and heat treatment states, such as Al-Mn, Al-Mg, Al-Mg-Si, Al-Cu-Mg, Al-Zn-Ma, jne. have been developed. These alloys have different characteristics and functions, greatly The use of aluminum has been expanded, and the application of aluminum in industrial sectors such as construction, autot, railways, ships and aircraft manufacturing has been rapidly developed.

During the Second World War, the aluminum industry achieved rapid growth under the strong stimulation of the military industry. sisään 1943, the total output of primary aluminum soared to 2 million tons. After the war, due to the sharp drop in military demand, the total output of primary aluminum dropped to 1 million tons in 1945. Kuitenkin, as major aluminum companies actively developed new civilian products, the application of aluminum materials was gradually extended to instrumentation, electronic and electrical transportation, Various fields such as daily hardware and food packaging have increased the demand for aluminum year by year. sisään 1956, world aluminum production surpassed copper, ranking first among nonferrous metals.

By the early 1980s, the world’s primary aluminum production had exceeded 16 million tons, and secondary aluminum consumption reached 4.5 million tons. The production scale and production technology level of the aluminum industry had reached a very high level.

Tieteen ja tekniikan jatkuvalla edistymisellä, the application fields of aluminum continue to expand and innovate. Esimerkiksi, aluminum alloys are widely used in the aerospace industry, as well as in electrolytic capacitors, solar panels and electric vehicles.

Overall, aluminum has experienced a transformation from a rare metal to a wide range of applications over the past two centuries. Its cost reduction and performance improvement have made it an important material that plays an important role in modern industry and life. effect.
