The best aluminum surface corrosion protection

aluminum, It is light in weight and strong in plasticity. 

It is used in many manufacturing projects because it provides these attributes at a moderate cost. But if there is no suitable aluminum surface, the corrosion begins almost immediately. Your customers don't want this. So how can you best use this silver-white metal without worrying about it corroding? You protect it. And protect it quickly.

What is the best aluminum finish for your project?

You can choose from a variety of aluminum finishes. Here are some of the most common ones:

Pretreatment

Level: Basic requirements. Aluminum must be pretreated to reach its potential. The aluminum is first peeled off, free of film, oil, etc., and then the pretreatment solution is applied. The aluminum is pretreated to provide corrosion protection and to prepare a surface for the coating. This pretreatment can enhance future coatings or powder coatings and help them better adhere to aluminum.

Paint

Level: Weak. Who likes to add some color to their project? Of course, all of us.

Therefore, the coating is very popular as a protective layer. But the paint is beautiful and not corroded.

If you insist on using paint as a protective layer, keep in mind that wet paints that are more difficult to paint (ie, paint coats) are more effective. Coatings containing Kynar® ️500 resin are rated as the best coatings for up to 20 years of non-corrosive use indoors and outdoors.

Powder coating

Ranking: Go there. If you are considering environmental regulations and a more evenly distributed surface treatment, then powder coatings are your first choice. Powder coating services provide a dense surface treatment for metal products that is more durable than coatings.

The powder coating is applied as a solid material which melts during processing and becomes a thin film layer on the aluminum.

(The interesting fact is that powder coatings are also less wasteful and more cost effective. Any powder that misses the target can be easily sucked out and reused in a vacuum-like device. This is not possible with paint or any other type of coating. Aluminum finish.

Anodizing

Ranking: Best. Anodizing is an excellent and natural way to protect aluminum. This self-forming protective layer does not peel or peel off. Suppliers can accelerate the anodizing process and get your aluminum ready for prime time.

If you want extra protection in harsh environments, you can choose hard-coat anodizing. The main difference here is that the hard coat anodization produces a more wear resistant, smoother and harder surface than standard anodization. This almost anti-corrosion option reduces the color you choose to black, gray or transparent.

Mechanical surface treatment

Level: Change. Aluminum can also be treated by mechanical surface as follows:

polishing

polishing

grinding

blasting

Sanding

These processes improve surface quality and prepare for other surface treated aluminum. With another finishing technique, higher quality surfaces are easier to protect.

Let your project be made of aluminum

Not all projects are the same, not all designs are only concerned with corrosion protection. Some people need to be nervous on the budget. Some people need to look great.

If you want to make your project shine, you need to know which aluminum coating is best for your application and at a reasonable cost. Will your project be outdoors? Under chemical pressure?

To save time and cost, consider how to complete aluminum from the start - during the design phase. If you have questions about the best choice for an aluminum project, we are here to help.
