Product Description

Electropolished Precision Spare Parts in Hard Aluminum Alloy Design

Product Description
Hard Aluminum Alloy CNC Milled Components with Color Anodizing combine high-strength alloy machining with vibrant, durable finishes. We transform alloys like 6061-T6 and 7075-T6 into complex, tight-tolerance parts with superior strength-to-weight ratios and surface quality via advanced CNC milling. Post-machining, components receive professional anodizing (Type II) in a wide color range, from black to vibrant shades. This process yields functionally and aesthetically superior components ideal for applications demanding high performance and visual appeal.

Product Processing
Material Selection & Verification: High-strength aluminum alloys (6061-T6, 7075-T6, 2024) are chosen per application needs. Certifications are verified, and stock is precision-cut to optimized sizes.
Precision CNC Milling (Core Process): Blanks are machined on advanced 3, 4, or 5-axis CNC centers using high-speed strategies for tight tolerances (±0.005mm), complex geometries, and excellent finishes. Critical features like pockets, holes, threads, ribs, and 3D contours are machined here.
Deburring & Surface Preparation for Anodizing: Post-machining, edges are meticulously deburred. Parts undergo a rigorous pre-anodizing cleaning, including degreasing, etching, and desmutting, to ensure a uniform, high-quality anodized finish.

Material Options	Standard Alloys	6061-T6(General purpose, good machinability, corrosion resistance)
	High-Strength Alloys	7075-T6(Aerospace grade, highest strength),2024-T3/T4(High strength, good fatigue resistance)
	Key Properties	Exceptional strength-to-weight ratio, excellent machinability, good corrosion resistance (alloy dependent)
CNC Milling Capabilities	Process	3-Axis, 4-Axis, 5-Axis Simultaneous CNC Milling, High-Speed Machining
	Positioning Accuracy	±0.005 mm
	Repeatability	±0.002 mm
	Surface Finish (Pre-Anodize)	Standard:Ra 0.8 µm.High-Gloss Prep:Ra 0.4 µm or better
	Minimum Feature Size	0.3 mm (e.g., thin ribs, small holes)
Anodizing (Type II)	Process Standard	Sulfuric Acid Anodizing perMIL-A-8625 Type II/AMS 2471
	Coating Thickness	5 – 25 µm (0.0002" – 0.0010") - Uniform and controlled
	Hardness	200 – 400 HV (Vickers Hardness) - Scratch resistant
Color Options - Full Spectrum	Electrolytic (2-Step)	Black, Bronze, Champagne, Stainless Steel look - Excellent UV stability for outdoor use
	Organic Dye	Vibrant Colors:Red, Blue, Green, Gold, Purple, Orange, Yellow, Pink, Teal, Turquoise
	Custom Color Matching	Available upon request (e.g., Pantone, RAL, Munsell matching)
	Color Uniformity	Consistent across all surfaces of a part and from part to part within a batch
Performance (Post-Anodize)	Corrosion Resistance	Excellent.Salt spray resistance per ASTM B117 (hours dependent on thickness/seal quality)
	Wear Resistance	Significantly improved over bare aluminum
	Electrical Insulation	Dielectric breakdown voltage typically > 400V per 25 µm
	UV Resistance	Electrolytic colors:Excellent.Organic dyes:Good for indoor use; consult for outdoor applications
Dimensional Considerations	Growth (Build-up)	Anodizing adds ~50% of thickness outward, 50% inward. For tight tolerances, pre-anodize dimensions must account for final thickness
Quality Assurance	Inspection Equipment	CMM, Optical Comparator, Surface Roughness Tester, Eddy Current Thickness Tester, Spectrophotometer (for color)
	Anodizing Tests	Thickness measurement, seal quality test (dye spot or acid dissolution), visual color match
	Material Certification	Mill Test Certificate (MTC) per EN 10204 3.1 provided
	Anodizing Certification	Certificate of Compliance with thickness and color specifications
Production Details	Maximum Part Size	Up to 1200 x 800 x 600 mm (dependent on machine)
