aluminum mill finish

Mill finish aluminium means the extrusion products without any surface treatment; Common Mill finish aluminium metal are aluminum sheet, aluminum plate, aluminum coil, aluminum foil, aluminum disc/circle, aluminum checkered/tread plate, aluminum embossed coil/sheet etc.

The 2 main reasons for choosing Mill finish aluminum:

Aluminum is versatile and relatively low-cost. It has a high strength-to-weight ratio and possesses non-corrosive properties. It is environmentally friendly and can accept high-performance coatings.

Reason #1: Finishes can improve corrosion resistance.

Aluminum has a naturally occurring oxide film that protects it from corrosion. This oxide film is sufficient for many applications. But in extreme environments, extra protection may be needed.

Reason #2: Finishes can enhance the appearance of the aluminum.

Depending on the look you are trying to achieve, you will need to select the appropriate finish. Maybe you want something that’s brightly colored. Maybe you’re trying to achieve a “mirror” finish. You need to choose a finish that will give you the look you want to achieve.

What is meant by “Mill Finish”?

“Mill Finish” is the term that Tigers aluminum uses to describe its aluminum trims that have no finish applied to them. It is raw aluminum from our mill and it can be field primed and painted. Typically, Mill Finish has a shiny or “mirror-like” appearance with some visible manufacturing lines.

What is meant by “Mill Finish” is aluminum in its original form and appearance as its comes directly from the rolling mill or an aluminum extrusion mill.

Here are 6 different types of finishes for extruded aluminum:

  • #1 Mechanical Finishes.
  • #2 Pretreatment. The aluminum is either etched or cleaned with alkaline or acidic materials.
  • # 3明亮的浸渍。
  • #4 Anodizing.
  • #5 Liquid Paint.
  • #6 Powder Coating.
  • #7 Sublimation.

Here are some of the mill finish aluminium sheets produced by Tigers aluminium to help you have a better understanding.

Here are 6 different types of finishes for extruded aluminum:

#1 Mechanical Finishes

Aluminum can be buffed, blasted, polished, grinded or sanded. These finishes can improve surface quality or prepare the aluminum for other cosmetic finishes.

#2 Pretreatment

铝与alka蚀刻或清洗line or acidic materials. Then a pretreatment coating is applied. This coating enhances powder or paint adhesion and provides resistance against corrosion.

#3 Bright Dipping

An extrusion can be bright dipped, giving the aluminum a specular or “mirror” finish. To do this, technicians put the profile into a special dip solution (a combination of hot phosphoric and nitric acids). After bright dipping, profiles can also be anodized, thickening the metal’s corrosion-resistant oxide layer.

#4 Anodizing

This electrochemical process provides additional protection aside from the natural oxide film. A durable, porous anodic oxide layer is formed on the surface of the aluminum. Anodized aluminum will also accept vibrant colors. You can anodize any kind of aluminum alloy.

#5 Liquid Paint

These coatings come in many colors and provide a uniform film thickness. Liquid coatings generally contain volatile organic compounds (VOCs). They are driven off during the curing or baking process. When the VOCs are gone the volume solids form a film on the extrusion.

#6 Powder Coating

Powder coatings leave behind a film that can meet stringent performance criteria. At the same time, they do not contain VOCs. This is ideal for meeting environmental regulations on VOCs. The product is applied as a solid on the extrusion. While going through the oven process, solid particles fuse together to form the film.

#7 Sublimation

Have you ever seen aluminum extrusions that look like wood? After applying a base coat of powder, profiles can go through sublimation. Technicians wrap the profiles in a thin film with a pattern on it. The sublimation process transfers that pattern directly onto the extrusions.

Packing

Aluminum products of Tigers meet the export popular.

Plastic movie and brown paper can be protected at customers’ need. Also timber case or timber pallet is adopted to shield products from harm for the duration of the delivery.

There are styles of packaging, which is eye to wall or eye to sky. Customers can choose either of them for their convenience.

There are 2 tons in one package, and loading 18-22 lots in 1×20′ container, and 20-24 tons in 1×40′ container.
