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.
