Surface Finishes

Finishes designed to enhance corrosion resistance, surface quality, and durability

  • Anodizing: Creates a hard oxide coating to protect aluminum against abrasion and oxidation.
  • Alodine: Chemical film that maintains conductivity while adding corrosion protection.
  • Passivation: Enhances stainless steel’s corrosion resistance by removing surface contaminants.
  • Electropolishing: Produces a bright, smooth, and contaminant-free surface for clean cabin applications.

FAQ

Frequently Asked Questions

These are our common FAQs. If you need specifics: such as machines, quoting, lead time, shipping, quality process, packaging, or payment, please email info@aerocncparts.com.

Our engineers will reply with clear, detailed information.

Can you integrate wire channels or hinge mechanisms into the armrest bracket design?
Yes. We can machine internal slots, hinge housings, or wire passages directly into the bracket to support power, control, or recline systems.
Are lightweight composite options available for business-class seating?
Yes. We can incorporate CFRP inserts or hybrid metal-composite designs to reduce mass while maintaining stiffness and durability.
How are surface finishes selected for interior components?
Finishes are chosen based on visibility, corrosion exposure, and contact frequency. Powder coating and electroless nickel are ideal for exposed parts, while anodizing is preferred for hidden structural fittings.
What quality verification steps are followed before shipment?
Every batch undergoes dimensional inspection using CMM, surface roughness measurement, visual defect checks, and document validation, as per AS9100D and PPAP standards.
Can you provide a DFM for armrest bracket models to facilitate weight reduction?
Yes. Our engineers provide design-for-manufacturing (DFM) feedback, suggesting geometry optimization and material substitution to reduce weight without compromising strength or performance.
