Introduction to aluminum alloy door - Features - Classification: the titanium magnesium aluminum alloy door is made of titanium magnesium aluminum alloy and glass as the primary material, and its function comes from the excellent function of titanium magnesium aluminum alloy.
Titanium magnesium aluminum alloy door is made of titanium magnesium aluminum alloy and glass. The excellent function of titanium magnesium aluminum alloy door comes from the excellent function of titanium magnesium aluminum alloy. Now titanium magnesium aluminum alloy door head to have titanium magnesium aluminum alloy security door, titanium magnesium aluminum alloy bathroom door and so on.
The following is a brief introduction of titanium magnesium aluminum alloy materials
Titanium is an isomer with a melting point of 1720 ℃ and a close packed hexagonal lattice structure below 882 ℃, which is called α - titanium; when it is above 882 ℃, it has a body centered cubic structure, which is called beta titanium. Using the different characteristics of the above two structures of titanium, adding appropriate alloy elements, and gradually changing the phase transformation temperature and phase content, titanium alloys with different arrangements are obtained. At room temperature, titanium alloys have three matrix arrangements, and titanium alloys can be divided into the following three categories: α alloy, (α + β) alloy and β alloy. China's parting is represented by TA, TC and TB.
Titanium alloy has high strength and low density, good mechanical function, good toughness and corrosion resistance. In addition, titanium alloy has poor process function and is difficult to cut. In hot working, it is easy to absorb impurities such as hydrogen, oxygen, nitrogen and carbon. There are also poor wear resistance, production technology is messy. The industrial production of titanium began in 1948. The demand of aviation industry makes titanium industry develop at an average annual growth rate of about 8%. At present, the annual output of international titanium alloy processing materials has reached more than 40000 tons, and there are nearly 30 kinds of titanium alloy grades. The most widely used titanium alloys are Ti-6Al-4V (TC4), ti-5al-2.5sn (TA7) and industrial pure titanium (TA1, TA2 and TA3).
Magnesium is one of the most widely distributed elements in the earth's crust, accounting for 2.77% of the crustal component, and is the fourth most abundant metal element (located after al, Fe, CA). Magnesium can only be found in natural compounds. Among the known 1500 kinds of mineral deposits, there are more than 200 kinds of magnesium ore deposits, mainly carbonate, silicate, sulfate, oxide, marine and Salt Lake magnesium is more than land, is the primary origin of magnesium. There are more than 10 elements in seawater, and magnesium content ranks the third, after Na and K. The magnesium content in seawater is 0.13%, and there are 1.3 million tons of magnesium in seawater per cubic kilometer, which is 4 times of the international annual consumption of magnesium (see table 2.8). The magnesium concentration of salt lake water is higher than that of sea water. The "Dead Sea" (actually another inland lake) between Israel and Jordan in the East was created by a dry climate of 10 million. The lake water is extremely thick, and its magnesium content is as high as 4%. Magnesium in this area alone can meet the demand of 22000 years in the whole world.
