Common Surface Finishes for CNC Aluminium Parts
We offer a range of surface finishes to enhance both aesthetics and functionality, providing optimal protection against corrosion. Our anodizing processes exceed industry standards, with many finishes passing rigorous salt spray tests of 72 hours or more.
Machined + Anodized: Combines precision machining with a durable, corrosion-resistant anodized coating for a sleek and professional look.
Brushed + Anodized: Creates a sophisticated matte finish with the added benefits of anodizing.
Sandblasted + Anodized: Provides a textured surface with enhanced durability and corrosion protection.
Hard Anodized: Delivers exceptional hardness, wear resistance, and corrosion protection. While typically available in black, it offers superior durability compared to standard anodizing.
Your questions answered
Common questions
What factors affect the price of an aluminium machined part?
Several factors influence the price of an aluminum machined part. These include:
Dimensional tolerances: Tighter tolerances require more precise machining, increasing cost.
Surface finish: A finer surface finish (lower Ra value) generally demands additional processing steps, impacting price.
Part complexity: Features such as small radii (R less than 1mm), internal right angles, or small, long holes can increase machining time and cost.
Hole diameter: Precision machining of small holes (under 1mm) requires specialized tooling, contributing to higher costs.
Small long holes: These features can also increase machining time and cost due to the specialized tooling and processes required.
Can you provide material certificates for your machined aluminum parts?
Yes, we can provide material certificates for all our machined aluminum parts. We source our aluminum raw materials exclusively from leading suppliers known for their high-quality products.
These certificates detail the complete chemical composition of the material and guarantee that all parts are made from virgin aluminum.
What is the difference between hard anodizing and regular anodizing?
Hardness
- Hard Anodizing: Significantly harder than regular anodizing. This increased hardness makes it ideal for applications requiring high wear resistance, such as engine components and molds.
- Regular Anodizing: Less hard compared to hard anodizing. Suitable for decorative purposes and general corrosion protection.
Coating Thickness
- Hard Anodizing: Typically has a thicker coating compared to regular anodizing. This thicker layer provides enhanced protection against wear, corrosion, and abrasion.
- Regular Anodizing: Offers a thinner coating, primarily focusing on aesthetics and basic corrosion resistance.
Unit Price
- Hard Anodizing: Generally more expensive due to the longer processing time and specialized equipment required for the thicker coating.
- Regular Anodizing: Typically more cost-effective compared to hard anodizing.
Anti-Corrosion and Wear Performance
- Hard Anodizing: Offers superior anti-corrosion and wear resistance. Ideal for applications exposed to harsh environments or experiencing high levels of friction.
- Regular Anodizing: Provides good corrosion protection but is not as resistant to wear as hard anodizing.
Color Options
- Hard Anodizing: Primarily limited to dark colors, such as black, due to the thickness of the coating.
- Regular Anodizing: Offers a wider range of color options, including bright and vibrant colors.
What are the different grit options available for brushed and sandblasted finishes?
Grit options for brushed and sandblasted finishes typically range from 80 to 150 grit. The most common grit used for these finishes is 120 grit.
It’s important to note that the higher the grit number, the finer the abrasive, resulting in a smoother surface finish.
However, it’s essential to remember that a higher grit number may not effectively mask defects such as scratches or machining marks.
