Aluminum surface treatments fall into two broad categories: anodized and painted. They all have two main goals: to enhance the aesthetic of the product and to provide additional protection to the surface.
Whatever surface treatment is chosen, we must not forget that aluminum retains the properties that make it such a widely used material:
- Versatility: Rugged and durable, aluminum can be used in many different end applications in many fields
- Processability: It’s an easier metal to work with. Bending, forging, laminating, stamping, extrusion; Any manufacturing process can be used for aluminum
- Lightweight: One-third the weight of steel for the same volume
- Thermal conductivity: Aluminum is a better conductor than steel, brass, and copper
- Recyclability: It’s a material that can be recycled indefinitely, 100 percent, and uses only 5 percent of the electricity needed to make primary products
Paint is one of the most commonly used aluminum finishes. The material can be coated with paints of different colors and properties. Depending on the final application, the option may be to increase the corrosion resistance of aluminum, limiting the formation of a coating on its surface by condensation or the growth of fungi and bacteria.
