In life, we can often see aluminum products. For example: cans, thermos bottles, pots and pans… They are all made of aluminum. These things are cheap and durable, so people love them. In fact, in addition to tableware and cooking utensils for daily use, aluminum materials are also used in cars. Take my country’s most advanced high-speed trains for example! According to reports, the aluminum profiles used in the “Harmony” EMU from Beijing to Guangzhou are all 5083 aluminum alloy. The weight of this aluminum profile is only 1/3 of that of ordinary steel, but its strength has reached or exceeded the level of ordinary carbon steel.
Aluminum alloy has the advantages of light weight and high strength. Aluminum alloys are required for the landing gear and propeller blades of modern aircraft. Aluminum alloys are also used in aircraft engine cylinder blocks and steam turbine blades. Many aluminum alloy materials are also used in the return capsule of the “Shenzhou V” manned spacecraft developed by our country. Today, with the rapid development of the aerospace industry, aluminum has been recognized as one of the most ideal structural materials.
“Light weight” is a major characteristic of aluminum. The density of aluminum is less than 2.7g/cm3, while the density of steel of the same specification is about 7.8g/cm3, and the weight of aluminum is only two-thirds of that of steel. Therefore, aluminum is a veritable “light metal”. Compared with other traditional engineering materials, aluminum also has many advantages such as energy saving and environmental protection, shock absorption and impact resistance, sound absorption and noise reduction.
In the field of construction, aluminum alloy not only exhibits good elongation and bending fatigue resistance, but also has good processing performance, which makes designers marvel. Aluminum alloy itself has no magnetism, will not interfere with electronic instruments, and has low thermal conductivity and fast heat dissipation. It is suitable for roof and wall panels of buildings; aluminum alloy materials are easy to form, easy to construct, and have good fire resistance , can replace wood and save forest resources; aluminum alloy profiles have precise cross-sectional dimensions, simple and flexible installation, firm and stable connections, and strong bearing capacity, which can meet the needs of various building door and window frames and curtain wall frames. The aluminum alloy profile also has a unique color effect, and different colors can be customized according to the individual needs of customers, fully demonstrating the fashion style.
The aluminum alloy material is non-toxic, tasteless, green and environmentally friendly, which is in line with the current concept of “green consumption”. In the field of transportation, aluminum alloy profiles have many advantages such as light weight, high strength, good toughness, long life, and low price, which perfectly fit the development trend of future transportation.
