Materials for Connector Plates

High-performance metals are used for durability, weight balance, and environmental resistance.

Aluminum 7075-T6 Stainless Steel 17-4PH Titanium Grade 5 Inconel 625 Copper
Surface Finishes

Each surface treatment enhances the plate’s protective and functional characteristics.

  • Anodizing: Adds a corrosion-resistant, hard oxide film on aluminum surfaces.
  • Alodine: Chemical coating that improves conductivity and corrosion defense.
  • Passivation: Strengthens stainless steel’s resistance to oxidation.
  • Electropolishing: Refines surface texture for reduced friction and a mirror-like finish.

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 connector plates be optimized for reduced weight?
Yes. Lightweight alloys, such as aluminum or titanium, are commonly used to minimize aircraft mass without compromising structural integrity.
Are these plates adaptable for hybrid mechanical-electrical interfaces?
Yes. They can serve dual purposes, providing both mechanical support and electrical conduction, depending on the coating type and base material.
How is flatness maintained during machining?
Thermal control and precision fixturing ensure parallelism and flatness within the specified limits, even on large or thin plates.
What certifications apply to production and finishing?
All operations adhere to ISO 9001 and AS9100D standards, while coating and surface finishing are performed under NADCAP approval.
Can you produce multi-hole or multi-layer plate assemblies?
Yes. Complex plate assemblies with varying hole patterns, slots, or stacked layers can be accurately machined for both prototype and full production runs.
