Product Introduction
Aluminum Radiator Header Plate for Automotive Water Tanks
CNC-pierced and flux-coated, these AA3003+4343/4045 aluminum header plates form the precision interface between the radiator tank and the micro-channel core.
1. Thickness 1.5–3.0 mm, width up to 800 mm, length on request
2. Hole pattern ±0.05 mm true position, compatible with 6–90 port flat tubes and ISO/PAG brazing fixtures
3. Clad ratio 8–10 % each side, melts at 605 °C to create a self-healing fillet, eliminating post-braze leaks
4. Pre-temper H24, post-braze yield ≥95 MPa, salt-spray >1 000 h per ASTM B117
5. Laser-etched part number & 2-D code for 100 % traceability
Features
The gaps between the holes on the radiator header plate are the same. Burr-free and Smooth,High Strength, Heat Resistance, Corrosion Resistance
Applicable
Ready for CAB, NOCOLOK® or vacuum brazing lines—tight flatness (<0.1 mm/100 mm) guarantees uniform core-to-tank gap for robotic flame brazing.
