An Aluminum nuts purple oxide is a type of fastener that has undergone a specialized surface treatment to achieve a decorative and corrosion-resistant purple finish. Here’s a detailed description:

1. Material

  • Made from aluminum (typically grades like 6061 or 7075 for a balance of strength and lightweight properties).

2. Purple Oxidation Process

  • The nut undergoes anodizing, an electrochemical process that thickens the natural oxide layer on aluminum.

  • The purple color is achieved through dye infusion during the anodizing process, where the porous oxide layer absorbs a purple dye before sealing.

  • Alternatively, electrolytic coloring (using metallic salts) can produce iridescent or darker purple hues.

3. Features & Benefits

  • 耐腐蝕性 – The anodized layer protects against rust and environmental damage.

  • Aesthetic Appeal – Provides a vibrant, consistent purple finish for decorative or color-coding purposes.

  • 耐用性 – Harder surface than raw aluminum, improving wear resistance.

  • Electrical Insulation – Anodized aluminum is non-conductive.

4. Common Applications

  • Aerospace & automotive (lightweight, corrosion-resistant fasteners).

  • Electronics & machinery (color-coded components).

  • Aluminum nuts purple oxide

  • Marine & outdoor equipment (enhanced weather resistance).

5. Variations

  • Bright Purple – Vivid, dye-based anodizing.

  • Iridescent Purple – Created via interference effects in hard anodizing.

  • Matte or Gloss Finish – Depending on pre-treatment (e.g., bead blasting for matte).

6. Limitations

  • Not as strong as steel nuts for high-torque applications.

  • The color may fade under prolonged UV exposure unless specially sealed.
