Aluminum product classification and use

News Details
First, the natural characteristics of aluminum
Aluminum is a light metal, and its compounds are widely dispersed in the natural world. The resources of aluminum in the earth's crust are about 40-50 billion tons, second only to oxygen and silicon. Among the metal types, second only to steel, it is the second largest class of metals. Aluminum has special chemical and physical properties, not only light weight, firm texture, but also excellent ductility, electrical conductivity, thermal conductivity, heat resistance and nuclear radiation resistance. It is an important basis for the development of the national economy.
Aluminum has a specific gravity of 2.7 and a density of 2.72 g/cm3, which is about 1/3 of the usual metal. In addition to the purity, the mechanical properties of industrial pure aluminum are related to the processing status of the data. Because aluminum is excellent in plasticity and ductile, it is easy to process various cold and hot pressures. It can be made into aluminum foil with a thickness of only 0.006 mm, or it can be cold-drawn into a very fine wire. By adding other elements, aluminum can be alloyed to harden it, strength can even exceed structural steel, but still maintains the advantages of light weight.
The production of aluminum ingots is composed of bauxite excavation, alumina production, and aluminum electrolysis.
Second, aluminum and aluminum commodity classification
1. Production process of electrolytic aluminum: bauxite → alumina → electrolytic aluminum.
2. According to the main component content of aluminum ingot, it can be divided into three categories: high-grade pure aluminum (aluminum content 99.93%-99.999%), industrial high-purity aluminum (aluminum content 99.85%-99.90%), industrial pure aluminum (aluminum content) 98.0%-99.7%).
3, according to the market type of aluminum ingots can be divided into three categories: one is processed materials, such as plates, belts, foils, tubes, rods, forgings, powders, etc.; one is forged aluminum alloy, wire rod cable Etc.; one type of aluminum products in ordinary days.
4.Rolled and rolled wood, rolled rolled material, non-heat treated alloy, pure aluminum alloy (1000 series), aluminum-manganese alloy (3000 series), aluminum-bismuth alloy (4000 series), aluminum-magnesium alloy (5000 series), heat-treated alloy, aluminum-copper-magnesium alloy (2000) Series) Aluminum Magnesium Niobium Alloy (6000 Series) Aluminum Zinc Magnesium Alloy (7000 Series) Casting Material Non-heat Treated Alloy Pure Aluminum Alloy Aluminum Niobium Alloy (ADC1) Aluminum Magnesium Alloy (ADC5, ADC6) Heat Treated Alloy Aluminum Copper Beryllium Alloy (ADC10) , ADC12) Aluminum Copper Magnesium Niobium Alloy (ADC14) Aluminum Magnesium Niobium Alloy (ADC3) Aluminum Finished Product Classification: Rolled Products: Sheet, Plate, Coil, Strip Extrusion products: pipes, solid bars, profiles. Casting products: castings.
Third, the main use of aluminum
In the past 50 years, aluminum has become one of the most widely used metals in the world. Especially in these years, aluminum as an environmental protection material for energy conservation and consumption reduction, regardless of the scale of use, is still expanding. Especially in the construction, transportation and packaging industries, the aluminum costs of these three occupations usually account for 60% of the total aluminum consumption of the year.
In the construction industry, aluminum is widely used in the construction industry because of the stability of aluminum in the air and the excellent appearance after anode treatment, especially in aluminum alloy doors and windows, aluminum-plastic pipes, decorative panels, aluminum plates. The use of curtain walls and other aspects.
In the transportation industry, in order to reduce the weight of the vehicle itself and reduce the pollution of the exhaust gas to the environment, many vehicles, such as motorcycles, trains, subways, airplanes, ships, etc., use aluminum and aluminum alloy as components and Decorations. With the increasing hardness and strength of aluminum alloy processed materials, the share of the aerospace industry has been added year by year.
In the packaging industry, all types of aluminum foil for flexible packaging, all-aluminum cans, various types of caps, easy-to-open lids, and medicinal packaging are also expanding.
In the catering industry, metal aluminum was once used to make cookware, and it is very popular because aluminum pans are not easy to rust. Aluminum reacts with oxygen in the air to form a dense aluminum oxide film. However, scientifically proven aluminum Tableware is not suitable for cooking or storage of acidic, alkaline and salty foods for a long time, because acid and alkali salts can directly etch the protective film on the surface of the metal aluminum and the aluminum itself.

In other areas of spending, the use and application of electronic and electrical appliances, household appliances (refrigerators, air conditioners), and daily hardware are becoming more and more broad.
