CNC machined aluminum 6061 cooling plate

Description

1. Product Overview
This CNC machined cooling plate, fabricated from premium Aluminum 6061-T6, is a high-performance thermal management solution engineered for forced liquid or air cooling in demanding power electronics and industrial systems. Its primary industrial use lies in dissipating concentrated heat loads from IGBTs, laser diodes, battery packs, and EV traction inverters. The key value proposition is a superior balance of thermal conductivity, machined precision, and corrosion resistance, delivering predictable, repeatable thermal performance. Strategically, this product enables OEMs to reduce system failure rates, increase power density, and extend equipment lifecycle—critical factors as industries transition toward higher-efficiency, compact thermal architectures.

2. Key Specifications & Technical Characteristics

• Material Composition: Aluminum 6061-T6 (ISO 6361); Mg 0.8–1.2%, Si 0.4–0.8%, Fe ≤0.7%, Cu 0.15–0.4%, Cr 0.04–0.35%

• Grade & Temper: Aerospace-grade 6061, T6 temper (solution heat-treated + artificially aged)

• Thermal Conductivity: 167 W/m·K at 25°C

• Physical Characteristics: Precision flat-milled surface; standard flatness ≤0.1mm per 300mm; RMS surface finish ≤1.6µm; available in custom drilled through-channels, dual-pass serpentine, or pin-fin core designs

• Density: 2.70 g/cm³

• Pressure Rating: Leak-tested to 1.5 MPa (217 psi) with helium mass spectrometry (leak rate ≤1×10⁻⁶ mbar·L/s)

• Packaging Options: Individual VCI-coated poly bags + edge protectors + stacked in export-grade plywood crates (IPPC compliant)

• Shelf Life: Indefinite (non-perishable); no degradation under dry, non-corrosive storage

3. Core Industrial Applications

• Primary Industries: Electric vehicle drivetrains, high-power rectifiers, telecommunications base stations, medical imaging (MRI/X-ray), laser cutting systems, data center liquid cooling

• Operational Use Cases: Direct-mounted IGBT cooling for industrial motor drives; cold plate for 150–600A battery disconnect switches; uniform temperature control for Li-ion battery module interfaces

• Performance Advantage vs. Alternatives: Outperforms stamped or extruded aluminum plates via tighter flatness tolerance (lower thermal interface material pump-out); superior to copper in weight-critical EV applications (40% lighter with 70% of thermal conductivity at 60% lower material cost); resists galvanic corrosion when used with mixed-metal water-glycol loops

• Efficiency & Durability: Enables ΔT of <8°C across a 250×250mm plate at 2kW heat load (1 L/min water flow); designed for >10-year service life under thermal cycling (-40°C to +105°C)

4. Competitive Advantages

• Quality Consistency: 100% in-process CMM inspection; each plate serialized with dimensional and leak test report. ISO 9001:2025 and IATF 16949 certified facility.

• Supply Reliability: Three redundant CNC machining centers (Germany, South Korea, Mexico) ensure <10-day lead-time recovery from any regional disruption. Safety stock held for 20 standard sizes.

• Logistics Capability: Direct factory-to-port shipment with real-time trackable batches via RFID-coded pallets. Export documentation (BL, COO, packing list) provided within 24 hours of vessel departure.

• Price Competitiveness: Tier-1 aluminum coil purchasing agreement (2,000 MT annual volume) achieves 12–18% lower landed cost vs. regional job shops.

• Sustainability: 100% post-industrial scrap recycled into certified closed-loop billet; cooling channel designs optimized to reduce material usage by up to 22% without thermal penalty.

• Technical Support: Full CAD-to-manufacturing DFM review (72-hour turnaround); thermal simulation report (Ansys Icepak) included for orders ≥500 units.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 50 units (standard sizes up to 400×600mm) OR 10 units for custom port locations / integrated fittings

• BULK 20MT Loading Capacity: Approx. 1,200–1,800 units (depending on plate dimensions; e.g., 200×300×10mm plate → approx. 1,550 units per 20FT container, equivalent to 19.8 MT net weight)

• Container Load (20FT): Max 21.5 MT net (aluminum only); typical loading: 20 MT per 20FT general purpose container

Note: Quotations for <50 units available via express sample program (5–7 business day lead time).
