Tips for Troubleshooting Common Issues with Anodised Aluminium Extrusions

Anodised aluminium extrusions are a versatile and durable material used in a wide range of applications. However, even the most robust materials can encounter problems. This article provides troubleshooting tips for common issues that can arise with anodised aluminium extrusions, empowering you to restore their optimal performance.

1. Discoloration or Chalking

Discoloration or chalking can occur due to factors such as improper cleaning or exposure to harsh chemicals. To address this, thoroughly clean the surface using a mild detergent and soft cloth. If discoloration persists, consult a professional anodiser for specialised treatments.

2. Oxidation or Surface Defects

Oxidation or surface defects may result from moisture accumulation or abrasive cleaning methods. To prevent this, maintain a dry environment and avoid using harsh cleaning products. Regularly apply a protective coating to protect against moisture and oxidation.

3. Scratch Resistance

Anodised extrusions offer excellent scratch resistance, but excessive force or improper handling can still cause scratches. Use non-abrasive cleaning cloths and handle extrusions with care. If scratches do occur, touch-up solutions are available to restore the surface finish.

4. Electrical Conductivity Issues

Anodised aluminium is generally non-conductive. However, if the anodising process is not properly controlled, it can lead to electrical conductivity issues. Ensure that the anodisation process is executed by a reputable and experienced anodiser to minimise this risk.

5. Corrosion Resistance

Anodised extrusions possess exceptional corrosion resistance. However, extreme environmental conditions or improper maintenance can compromise this protection. Regular cleaning and periodic inspections are essential to maintain the integrity of the protective oxide layer.

Troubleshooting common issues with anodised aluminium extrusions requires a thorough understanding of the material’s properties and the potential causes of problems. By implementing these troubleshooting tips, you can effectively restore the optimal performance of your anodised extrusions, ensuring their durability and aesthetic appeal. Remember to consult with a professional anodiser for more complex issues or specialised treatments.
