Aluminum Material
Aluminum is an extremely important metal material in modern industry and daily life. It has a silvery-white metallic luster, a relatively light texture, and a density of about 2.7 g/cm3, which is only about one-third of the density of iron. This makes aluminum quite advantageous in applications that require weight, such as in the aerospace field, where aluminum and its alloys are used extensively to reduce aircraft weight, improving fuel efficiency and flight performance.
In machining manufacturing, aluminum is widely used because of some excellent properties, such as:
Aluminum has good electrical conductivity, which is about 60% copper, so it is also widely used in some power transmission fields, such as high-voltage overhead lines.
Aluminum also has excellent thermal conductivity and is a good conductor of heat. It is often used in the manufacture of heat exchange equipment such as radiators.
In terms of chemical properties, a dense aluminum oxide protective film is easily formed on the aluminum surface, which can effectively prevent aluminum from further reacting with substances such as oxygen and water, thereby making aluminum have good corrosion resistance under normal conditions.
Aluminum has good processing performance and can be made into products of various shapes and specifications, such as aluminum plates, aluminum foils, aluminum tubes, aluminum profiles, etc. through various processing techniques such as extrusion, rolling, forging, and casting.

Compared to steel, aluminum has lower hardness and may experience wear or deformation in scenarios involving high loads or intense friction.
Higher Cost
The raw material cost of aluminum is higher compared to ordinary steel, especially in the case of high-purity or special alloys.
High Surface Treatment Requirements
Although aluminum has natural corrosion resistance, surface treatments (such as anodizing) are still required in certain harsh environments to enhance durability, increasing process complexity.
Welding Difficulties
Some aluminum alloys are prone to cracking or porosity during welding, requiring special welding techniques and technical support.
