· Product Overview

· Core Specifications

• Material: 7075-T6 Aerospace-Grade AluminumTensile strength ≥572 MPa (far higher than 6061-T6), yield strength ≥503 MPa, and excellent fatigue resistance; suitable for high-load applications.
• Manufacturing Standard: ISO 9001-Certified Precision CNC Milling Process
  • Key Processes: 7075 aluminum bar stock → multi-axis CNC milling (component shapes + precision features) → black anodization (corrosion/wear protection) → deburring.
  • Dimensional Tolerance: ±0.02mm (ensures tight alignment of modular parts for high-precision assemblies).
  • Mounting Hole Specs: Standard M3/M4 threaded/unthreaded holes (uniform spacing for universal fastener compatibility).
  • Surface Finish: Black hard anodized (thickness 25–50μm; enhances hardness and corrosion resistance).

· Application Scenarios

• Aerospace & Defense: Small-scale avionic component brackets, UAV (drone) frame structural supports.
• Industrial Robotics: Robotic arm link brackets, actuator mounting blocks, high-torque system connectors.
• High-Performance 3D Printing: Heavy-duty printer frame supports, build plate mounting brackets.
• Precision Industrial Equipment: CNC machine tool accessories, sensor mounting chassis, high-load conveyor system brackets.
• Automotive Prototyping: Custom performance part supports, lightweight chassis components.

· Production Process Introduction

1. Raw Material Sourcing: Procure certified 7075-T6 aluminum bar stock (metallurgically tested for aerospace-grade strength and purity).
2. Multi-Axis CNC Milling: Use precision CNC mills to shape each component (L-brackets, U-connectors, etc.) and machine mounting holes/features to tight tolerances.
3. Black Hard Anodization: Submerge parts in electrolytic baths to apply a durable, wear-resistant black finish (boosts surface hardness to ~60 HRC).
4. Deburring & Finishing: Remove sharp edges (for safe handling) and polish mating surfaces (for seamless assembly).
5. Quality Inspection: Conduct CMM (Coordinate Measuring Machine) scans (dimensional accuracy) + tensile strength spot-checks + finish integrity verification.
6. Kit Assembly: Sort components by type and package as a standardized modular kit.

· Packaging and Shipping Methods

• Packaging: Each component is wrapped in anti-scratch film; the full kit is packed in a foam-lined, rigid cardboard box (labeled by part type to prevent damage and simplify assembly).
• Shipping: Flexible logistics options:
  • Express Delivery (DHL/FedEx/UPS: 3–5 business days)
  • Air Freight (7–10 business days)
  • Sea Freight (20–30 business days)All shipments include full tracking and damage insurance.

· Frequently Asked Questions (FAQ)

• MOQ (Minimum Order Quantity): 50 sets for standard configurations; 100 pieces per individual component type. Small sample kits (1 set) are available for performance testing.
• Lead Time: Standard lead time is 7–15 working days (due to precision CNC milling of 7075 aluminum); expedited production (5–7 working days) is available for urgent orders (additional fees apply).
• Customization Capability: We can adjust component dimensions, modify hole size/spacing, add threaded features, or create custom shapes per your technical drawings. Our engineering team will validate design feasibility for 7075 aluminum’s machining properties and load-bearing performance.
