Versatile Protection and Vibrant Colors for Aluminum

Metal Finishing Group provides Type II Sulfuric Acid Anodizing, the most widely used method for enhancing aluminum components. This electrochemical process forms a controlled aluminum oxide film on the part’s surface using a sulfuric acid electrolyte. The resulting coating offers a valuable combination of protection and aesthetic appeal.

Type II anodizing is a highly versatile surface treatment, providing good corrosion resistance, improved wear properties, and excellent electrical insulation. The unique structure of the anodic film allows for the absorption of dyes, making it possible to achieve a broad spectrum of colors. This makes it an ideal solution for components requiring both functional enhancement and specific visual identification or decorative finishes.

Our Type II Sulfuric Acid Anodizing Capabilities:

We offer comprehensive Type II Anodizing services, designed to deliver consistent quality and meet diverse project requirements.

  • Standard Film Thickness: Achieves a typical thickness ranging from 0.0001 to 0.0007 inches, balancing protection with minimal dimensional impact.
  • Clear Anodize: Provides a transparent, protective finish that maintains the natural metallic appearance of the aluminum.
  • Vibrant Dyeing Options: We offer a selection of 10 distinct colors to meet your branding, identification, or aesthetic needs
  • Precision Masking: Available for selective anodizing of specific areas on your parts.
  • Post Anodize Sealing: We offer sealing processes to enhance corrosion resistance by closing the pores of the anodic film.

Properties of Type II Anodizing:

Type II Anodizing imparts several key properties that extend the life and utility of aluminum components:

  • Good Corrosion Resistance: The aluminum oxide layer provides effective protection against environmental degradation.
  • Moderate Wear Resistance: The coating increases surface hardness, offering improved resistance to abrasion.
  • Excellent Electrical Insulation: The aluminum oxide film is dielectric, providing vital electrical isolation for many applications.
  • Enhanced Paint and Adhesive Adhesion: The porous surface acts as an excellent base for subsequent painting, powder coating, or bonding.
  • Aesthetic Versatility: Th ability to absorb dyes allows for a wide range of colored finishes, enhancing product appearance and branding.
