What is aluminum products?
Aluminum products are a collective term for daily necessities and industrial products made of aluminum alloy as the main raw material.
Aluminum is a chemical element. Its chemical symbol is Al, and its atomic number is 13. The content of aluminum in the earth's crust is second only to oxygen and silicon, ranking third, and it is the most abundant metal element in the crust. Among the metal varieties, it is the second largest metal after steel. It was not until the end of the 19th century that aluminum emerged as a competitive metal in engineering applications and became popular. Development of three important industries of aviation, construction and automobile
The material characteristics are required to have the unique properties of aluminum and its alloys, which greatly facilitates the production and application of this new metal aluminum. Aluminum is widely used.
Pure aluminum is very soft, not strong, and has good ductility. It can be drawn into thin wires and rolled into foils. It is widely used in the manufacture of wires, cables, radio industry, and packaging. Its conductivity is about two-thirds of that of copper, but because its density is only one-third of that of copper, compared with aluminum wires of the same quality and length and copper wires, the conductivity of aluminum is about copper Twice as much, and the price is lower than copper.
Aluminum alloy is a general term for aluminum-based alloys. The main alloying elements are copper, silicon, magnesium, zinc, and manganese, and the secondary alloying elements are nickel, iron, titanium, chromium, and lithium.
Aluminum alloy has low density, but relatively high strength, close to or exceeds high-quality steel, good plasticity can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, second only to steel.
