1. Material: AA3003 substrate, 8 % clad 4343 both sides (optional)
2. Gauge: 1.50 mm ±0.03 mm – minimizes deformation under 220 °C CAB cycle
3. Hole matrix: CNC punched 6–32 mm pitch, ±0.05 mm true position, burr <0.02 mm
4. Post-braze strength: 95 MPa yield, 45 MPa shear on tube-to-header fillet
5. Corrosion: >1 000 h SWAAT, zinc diffusion layer available for EV coolant compatibility
Applications
Aluminum Header Plate
1. Passenger-Car Radiators
Seals micro-channel or serpentine tubes to plastic/aluminum tanks; withstands 1.4 bar pressure & 120 °C coolant surge.
2. Light-Duty Truck & SUV Cooling Modules
Supports wider cores (≤800 mm) without sag; clad layer self-fillets for leak-free joints after CAB brazing.
3. High-Performance / Racing Radiators
1.5–2.0 mm gauges accept AN fittings and weld-on stubs for custom inlet/outlet configurations.
4. EV Battery Cold Plates & Power-Electronics Coolers
Zinc-diffused header plates resist glycol corrosion, maintaining <5 × 10⁻⁵ mbar·l/s leak rates over 3 000 h.
5. Aftermarket Replacement & Repair Cores
Drop-in hole patterns match OEM part numbers.
