FAQs
Q: How does powder coating differ from anodizing?
Eräs: Powder coating involves applying a dry powder to the aluminum surface and curing it under heat to form a protective layer. Unlike anodizing, which penetrates the metal surface, powder coating creates a thick layer on top. It provides a wide range of color options, excellent surface coverage, and good corrosion resistance.
Q: What is the purpose of brushing aluminum?
Eräs: Brushing aluminum involves creating a unidirectional satin finish by using abrasive brushes on the surface. This finish is primarily used for decorative purposes and is popular in architectural applications, keittiön laitteet, and consumer electronics for its sleek, modern look.
Q: When should I choose polishing as an aluminum finish?
Eräs: Polishing is used to achieve a mirror-like, highly reflective surface on aluminum. It is ideal for applications requiring an aesthetically appealing finish, such as automotive parts, signage, and decorative items. Kuitenkin, polished aluminum can be prone to scratches and may require regular maintenance.
