What Is Aluminum Processing And Aluminum Machining
Aluminum Machining is the use of aluminum ingots (or recycled aluminum) through various processes and processes such as casting, rolling, extrusion and surface treatment to produce final products for use in different industries.
Aluminum processing is divided into two forms: Deformation Processing And Casting Machining
Deformation processing is further divided into extrusion and calendering.
Products made by extrusion process are called extruded profiles, mainly including building profiles and industrial profiles;
The products made by the calendering process are called strips and foils, which mainly include various aluminum cnc machining service plates, strips and foils.
Casting Machining: through die casting, the original aluminum is processed into various precision aluminum castings and precision sheet metal.
The Features And Application Areas
The density of aluminum is 2.7g/cm (one-third of the density of iron and copper), the ductility is good, and the conductivity is two-thirds of that of copper wire, but the quality is only one-third of that of copper wire, and the price is cheap. It is widely used in the manufacture of high-voltage wires and cables.
2. Doors and windows
Lightweight, durable and inexpensive, aluminum alloy doors and windows are the first choice for home and office doors and windows. Compared with wooden doors and windows, aluminum alloys have lower maintenance costs, more affordable prices, and are more scratch-resistant and less prone to cracking and damage.
3. High-rise buildings
Aluminum is easy to process, has strong durability, strong corrosion resistance, and has an outstanding weight-to-strength ratio. It is widely used in the construction field and is a core value material for high-rise buildings and skyscrapers.

Industry Chain Analysis
Upstream: Bauxite mining is carried out first, and alumina is extracted by dissolving, filtering, acidifying and burning the bauxite, and then electrolytic aluminum is prepared by electrolytic melting.
Midstream: electrolytic aluminum can be further processed into various aluminum materials, aluminum alloys and aluminum powders after being remelted and purified.
Downstream: widely used in construction, packaging, transportation, electric power, aerospace and other fields
The upstream industrial chain of custom aluminum parts includes bauxite mining, alumina refining and primary aluminum production. The production of primary aluminum is relatively simple and mainly depends on resources and energy. Alumina + electricity together account for more than 80% of the entire production cost.
Global reserves of bauxite are abundant, mainly concentrated in countries close to the equator, including Australia, Guinea, Brazil, Vietnam and Jamaica, accounting for 64% of the world’s total reserves. my country’s reserves only account for 3% of the world’s reserves, but the distribution is highly concentrated. The four provinces of Guangxi, Henan, Shanxi and Guizhou together account for more than 90%.
Alumina is an intermediate link, and its output is mainly distributed in China, Australia and Brazil. China imports a large amount of bauxite from overseas, which is finally produced into alumina, and China’s alumina output accounts for about 50%, which can basically meet the needs of electrolytic aluminum. Production needs, only a small amount of imports.
The midstream of aluminum cnc turning is aluminum machining. The raw material electrolytic aluminum is produced through processes and processes such as casting, rolling, extrusion and surface treatment to produce aluminum profiles, pipes, bars and other extruded materials, plates, strips, foils and other flat-rolled materials. All kinds of aluminum materials such as materials and casting materials.
my country is a big country in aluminum machining. According to statistics, from 2015 to 2020, my country’s aluminum production increased from 52.364 million tons to 57.793 million tons, with an average annual compound growth rate of 2%. It is estimated that my country’s aluminum production will reach 53.89 million tons in 2021.
The primary aluminum is processed into aluminum processed materials, which are used in various downstream industries.
From the perspective of the structure of China’s aluminum materials: the proportion of aluminum profiles is the highest; followed by aluminum sheets, strips and foils; and finally aluminum die castings.
The downstream application fields of aluminum machining materials are very extensive, which are closely related to the industry, construction industry, and the improvement of consumption levels. From the perspective of downstream demand for custom aluminum milling materials, the construction sector is the largest consumer sector, followed by industrial sectors such as transportation, durable consumer goods, and power electronics.
The pricing model of aluminum machining materials is “electrolytic aluminum + processing fee”, which can partially transfer the risk of sharp fluctuations in upstream raw material prices, so the profitability of the aluminum machining china industry is relatively stable.
The Factors Affecting Spot Aluminum Prices
1. The influence of supply and demand
When the market supply and demand of aluminum is in balance, the aluminum price will fluctuate in a narrow range; when the supply and demand relationship is out of balance, the aluminum price will fluctuate greatly.
2. Supply of alumina
The cost of alumina accounts for about 28%-34% of the production cost of cnc milling aluminum ingots. Therefore, the supply quantity and price of alumina will directly affect the price of aluminum ingots.
3. Changes in electricity prices
The electrolytic aluminum industry is a power-intensive industry and has a large demand for energy-electricity. Therefore, in developing the electrolytic aluminum industry, countries must carefully consider the ability of sustainable energy-electricity supply. The power factor not only affects the production of electrolytic aluminum in China, but also affects the price of domestic and international aluminum markets.
4. The impact of changes in aluminum application trends
Changes in the amount of aluminum used in automobile manufacturing, construction engineering, wire and cable and other industries and industrial adjustments will have a great impact on aluminum production and market prices.
5. Import and export policies and exchange rates
Due to the rapid growth of the production capacity of domestic aluminum ingots, on the one hand, the domestic alumina supply is tight, and on the other hand, the macroeconomic environment determines that the demand for aluminum cannot grow too fast in recent years. It is beneficial to promote the export of domestic aluminum ingots. However, the high energy consumption and high cost of domestic aluminum ingot production restrict the development of my country’s aluminum ingot industry. Therefore, a certain amount of aluminum still needs to be imported every year to meet domestic demand, and my country’s adjustment of aluminum import and export tariffs will affect the domestic aluminum ingot industry. aluminum price.
The mainstream aluminum transactions in the world are all priced in US dollars. As one of the main import and export commodities, the exchange rate changes between the two sides of the trade have a significant impact on the price.
