"Mill finish" is a term for metal surface treatment, usually used for metal materials such as aluminum, copper, and stainless steel. It refers to the state of the metal after preliminary processing without any additional surface treatment or polishing. Specifically, mill finish aluminum coil refers to aluminum coils that maintain their natural surface state after rolling and other processing. This surface has not been subjected to additional decorative treatments such as painting and coating, but retains the original surface texture formed by the aluminum during the rolling process. Mill finish is usually used in the fields of construction, decoration, and mechanical parts, and is suitable for occasions where the appearance requirements are not high.

Features of mill finished aluminum coil:
- Appearance: It has a natural metallic luster, a relatively smooth and uniform surface, and presents the silver-gray tone of aluminum itself, giving people a simple and simple beauty.
- Corrosion resistance: Aluminum easily reacts with oxygen in the air, forming a dense aluminum oxide film on the surface. This oxide film can prevent the internal aluminum from being further oxidized, making the mill finish aluminum coil have a certain degree of corrosion resistance.
> - Good processing performance: Since there is no complex coating or treatment on the surface, mill finish aluminum sheet coil has good plasticity and processability, and is easy to perform various processing operations such as bending, stamping, stretching, welding, etc., which can meet the molding requirements in different application scenarios.
- Light weight: The density of aluminum is relatively low, which makes the weight of mill finish aluminum coil relatively light, which is more convenient and labor-saving during transportation and installation, and also reduces the weight of the overall structure.
- Recyclability: It has high recyclability, high recycling value, and conforms to the concept of environmental protection. It can be easily recycled and reused after the service life ends, and reused to produce new aluminum products.

Application field of mill finish aluminum coil:
- Construction industry: used for curtain walls, roofs, wall decorative panels, etc. on the facade of buildings. Its beautiful, durable and corrosion-resistant characteristics can improve the overall quality and service life of the building; it can also be used to make door and window frames, which can achieve good sealing performance and aesthetic effects.
- Packaging industry: widely used in the packaging of food, beverages, medicines, etc., such as making cans, food packaging foils, and pharmaceutical packaging bottles, which can not only protect the products from the influence of the external environment, but also have good barrier properties and aesthetics.
- Electronic and electrical industry: Due to its good electrical and thermal conductivity, it is used to manufacture radiators, circuit board substrates, housings and other components of electronic equipment, which helps to improve the heat dissipation performance and stability of electronic equipment.
- Transportation industry: It can be used to manufacture body structural parts, interior parts, radiators, etc. of vehicles such as cars, trains, and airplanes, which can reduce the weight of vehicles and improve fuel efficiency and operating performance.

The price of mill finish aluminum coils is affected by many factors, such as fluctuations in aluminum ingot prices, alloy composition, product specifications (thickness, width, length, etc.), production processes, market supply and demand, etc. Generally speaking, the price of ordinary 1000 series pure mill finish aluminum coils is relatively low, while the price of 3000 series, 5000 series, 6000 series aluminum coils containing special alloy elements is relatively high. In the current market, the price of mill finish aluminum coils is roughly between US$3,000 and US$3,500 per ton.
