Precision CNC Machining for Aluminum & Stainless Steel – Custom Finishing Including Anodizing & Passivation

### Introduction
We offer end-to-end CNC precision machining for both **aluminum** and **stainless steel** components, backed by a full spectrum of secondary finishing services. Whether you require **hardcoat anodizing** for lightweight aluminum parts or **passivation/electropolishing** for corrosion-resistant stainless steel, our ISO 9001:2015 facility delivers high-tolerance custom solutions. From rapid prototyping to high-volume production, every part is manufactured with strict dimensional control and full traceability.

## Core Content Highlights

**1. Multi‑Material CNC Expertise**
- **Aluminum:** 6061-T6, 7075, 2024, 6082 – ideal for anodized finishes.
- **Stainless Steel:** 303, 304, 316L, 17-4 PH – finished with passivation or electropolishing.
- **Hybrid Assemblies:** Machine both materials in one production run; anodize aluminum and passivate stainless steel to meet matching aesthetic or functional requirements.

**2. Precision Capabilities**
- 3‑, 4‑, and 5‑axis CNC milling & turning.
- Tolerances down to ±0.005 mm.
- In‑house CMM inspection and First Article Reports.

**3. Finishing Services – Clearly Explained**
| Material | Available Finishes | Benefits |
|---------------|-------------------------------------------------|-----------------------------------|
| Aluminum | Type II & III Anodizing (clear, black, colors) | Wear resistance, dye retention |
| Stainless Steel| Passivation, Electropolishing, PVD Coating | Oxide layer removal, smoothness, hardness |

*We educate customers upfront: anodizing is exclusive to aluminum. For stainless steel we recommend passivation or electropolishing – solutions that provide equivalent or superior corrosion protection.*

**4. Customization & Quality Assurance**
- Low minimum order quantities (MOQ 1 piece accepted).
- Surface roughness down to Ra 0.2 µm.
- 100% inspection for critical dimensions.
- Material certifications and RoHS/REACH compliance.

**5. Typical Applications**
- Aerospace brackets & housings
- Medical device components
- Automotive sensors & connectors
- Marine hardware
- Consumer electronics enclosures
