Product Overview
Precision Car Aluminum Radiator Header Plates
Car Aluminum Radiator Header Plates are critical structural components that serve as the primary sealing interface between radiator core tubes and plastic/aluminum tanks in automotive cooling systems. Manufactured through precision CNC stamping processes, these plates ensure leak-proof performance under high-pressure coolant circulation. Engineered for universal compatibility with 2-row, 3-row, and 4-row radiator configurations, they provide OEM-grade reliability for passenger cars, commercial vehicles, and performance applications.
Key Features & Benefits
Precision Car Aluminum Radiator Header Plates
Superior Material Properties
1. Material Grade: Premium 3003 aluminum alloy with optional 4343/3003/7072 multi-layer clad composite
2. Hydrophilic & Anti-Corrosion: Specialized alloy composition provides excellent corrosion resistance and superior brazing characteristics
3. Lightweight Design: 40% weight reduction vs. steel alternatives, improving fuel efficiency and handling
4. Surface Treatment: Hard anodized finish (25-30μm) with protective coating for extended service life
Multi-Row Universal Compatibility
1. Single Pattern Design: One header plate accommodates 2-row, 3-row, and 4-row radiator cores
2. Staggered Tube Slots: Precision-engineered geometry ensures proper tube alignment across all row configurations
3. Reinforced Structure: Internal ribbing prevents deflection under high pressure (rated to 4.0 bar)
4. Optimized Flow: Internal channels promote equal coolant distribution for maximum cooling efficiency
Precision Manufacturing
1. CNC Stamping: High-precision dies ensure ±0.05mm dimensional accuracy
2. Burr-Free Finish: Advanced processing eliminates sharp edges, preventing assembly damage and ensuring worker safety
3. Uniform Punching: Consistent hole spacing and TAB heights guarantee seamless core integration
4. Flatness Control: ≤0.2mm per 100mm length for perfect tank sealing
