· Product Overview
Introducing the YITECH Precision Copper-Anodized Aluminum Block — a CNC-machined structural & functional component engineered for electrical grounding, thermal management, optical alignment, and aesthetic integration in high-performance electronics and precision machinery.
This block delivers:
- Solid 6061-T6 or 2011-T3 aluminum construction — lightweight, strong, and highly conductive (electrical: ~35% IACS; thermal: 167 W/m·K)
- Unique copper-bronze anodized finish (Type II) — visually distinctive, corrosion-resistant, and electrically conductive (unlike standard black anodize)
- Integrated functional features:
- Internal threaded bore (M3/M4/M5) for secure fastening
- Precision through-holes for wire routing, shafts, or alignment pins
- Flat, parallel surfaces for reliable mounting and thermal contact
- Tight tolerances: ±0.01 mm on critical dimensions, ≤0.01 mm flatness — ensures zero misalignment in sensitive assemblies
Unlike generic plastic or steel brackets — which insulate, corrode, or add weight — our copper-anodized blocks offer true electrical continuity, superior heat dissipation, and premium visual identity, all in one part.
Ideal for designers building next-gen power electronics, RF modules, laser systems, or consumer devices where form and function must coexist.
· Core Specifications
| Parameter | Specification |
|---|---|
| Material | • 6061-T6 Al (standard): Best balance of strength, machinability, conductivity • 2011-T3 Al (optional): Higher machinability, better chip control, slightly higher Cu content (~5.5%) → enhances copper-like appearance & conductivity |
| Surface Finish | Type II Anodize, Copper-Bronze (RAL 8028 / Pantone 7519 C equivalent); conductive anodize (surface resistivity: 10⁴–10⁵ Ω/sq vs. 10⁹+ for standard anodize) — allows grounding without removing coating |
| Standard Configurations | • Block A (Threaded Hub): 25×20×25 mm, M4 internal thread (depth 10 mm), Ø6 mm side through-hole • Block B (Through-Hole Cube): 30×30×30 mm, Ø12 mm central through-hole, Ø4 mm side hole (for pin/clip) • Custom L/W/H up to 80×60×50 mm |
| Thread Options | M3, M4, M5 (standard); blind or through-tap; optional: left-hand thread or dual-thread (e.g., M4 + M3 coaxial) |
| Tolerances | • Length/Width/Height: ±0.01 mm • Hole position: ±0.01 mm • Flatness (top/bottom): ≤ 0.01 mm • Concentricity (bore to outer face): ≤ 0.015 mm |
| Electrical Properties | • Volume resistivity: 2.8 × 10⁻⁸ Ω·m (6061-T6) • Surface resistivity (anodized): ~50 kΩ/sq (conductive anodize) — groundable without stripping |
| Thermal Conductivity | 167 W/m·K (6061-T6); 170 W/m·K (2011-T3) — ideal for passive heat spreading |
| Weight (Example) | 25×20×25 mm, 6061-T6: ~10.8 g |
| Operating Temp. | -40°C to +150°C (anodized); up to +250°C (bare Al) |
| Compliance | RoHS, REACH, ISO 9001; FDA-compliant (USP Class VI for medical variants) |
· Application Scenarios
These blocks excel where electrical continuity, thermal management, and visual differentiation are critical:
- Power Electronics & EV Components
→ Grounding blocks for inverters, DC-DC converters, battery management systems (BMS)
→ Heat-spreading bases for MOSFETs, IGBTs, or SiC modules
→ Busbar transition adapters (copper-like appearance signals “high-current path”) - RF & Microwave Systems
→ Shielding housings for LNAs, filters, or mixers (conductive anodize enables EMI containment)
→ Waveguide flange adapters with integrated grounding points
→ Antenna feed network mounts - Laser & Optics
→ Mounting hubs for diode lasers (heat sink + electrical ground in one)
→ Kinematic base plates for mirror stages (copper tone aids visual alignment)
→ Fiber optic connector retainers with ESD-safe path - Consumer Electronics
→ Premium USB-C port surrounds (copper = “premium tech” signal)
→ Smartwatch charger docks with integrated grounding
→ Audio amplifier chassis accents (aesthetic + functional) - Industrial Automation
→ Sensor grounding blocks in high-noise environments
→ Modular fixture carriers with color-coded conductivity zones
→ Robotics joint housings with thermal + electrical integration
💡 Why engineers choose YITECH copper blocks:
- Conductive anodize = no extra grounding wires — saves assembly time & space
- 2011-T3 option = richer copper tone — more authentic than dye-only finishes
- CNC from billet = zero porosity — unlike cast parts that trap moisture or crack
- Custom in 6 days — not weeks — with full electrical validation

- Rush service (≤6 days): Available for +20% fee
Q3: Can I get true copper (Cu) instead of aluminum? Or add EMI gaskets, O-rings, or magnets?
A: Yes — full customization:
A: Yes — full customization:
- Material: Pure copper (C11000), brass (C36000), or aluminum (standard)
- Features: O-ring groove (AS568), press-fit magnet cavity, EMI finger stock slot, or integrated spring contact
- Finishes: Conductive black (for EMI), gold flash (for RF), or clear anodize + copper plating
- Note: Pure copper blocks are heavier (8.9 g/cm³) and softer — we recommend aluminum for most structural uses.
Q4: Is the “copper” color real metal, or just dye? Can it conduct electricity?
A: It’s not raw copper — it’s aluminum with a special conductive anodized layer. Key facts:
A: It’s not raw copper — it’s aluminum with a special conductive anodized layer. Key facts:
- The base is aluminum (lightweight, strong, machinable)
- The surface is dyed with copper-complex pigment + sealed with nickel acetate → retains electrical conductivity (unlike standard anodize)
- Surface resistivity: ~50 kΩ/sq (vs. >1 GΩ/sq for standard black anodize)
- We provide a conductivity test report with every batch
