Product Description

Description of the flange

Aluminum Alloy: Common options include 6061-T6 (tensile strength: 42-45 ksi) and 7075-T6 (tensile strength: 74-78 ksi). The latter, with strength close to steel and lighter weight, is the preferred choice for high-end modifications
Steel: Traditional steel flanges offer high strength but are heavier, gradually being replaced by aluminum alloys, and are now used only in specialized heavy-duty scenarios
Bolt Grade

Flange bolts must meet Grade 10.9 or higher to ensure connection reliability. Nuts are typically one grade lower (e.g., Grade 8) to avoid brittle fractures caused by excessive hardness
Manufacturing Process

10,000-ton forging process: Ensures material density and structural integrity.
T6 heat treatment: Includes solution treatment and artificial aging to enhance fatigue resistance
 
 
 
 
 
 

Spatial Compatibility
Unlike aftermarket radiators, OEM components perfectly align with the engine bay layout, avoiding installation conflicts (e.g., squeezing pipelines or electronics) and optimizing airflow guidance through shrouds to reduce aerodynamic losses.

Materials and Processes

Aluminum Alloy Welding: Utilizes vacuum brazing technology, with weld strength exceeding 350 MPa and corrosion resistance far surpassing conventional soldering. Annual leakage rates remain below 0.01%.
Fin Design: Corrugated or louvered stamping patterns, combined with hydrophilic coatings, enhance condensate drainage and prevent heat dissipation degradation caused by debris buildup.
Durability Testing
OEM radiators undergo extreme environment validation (e.g., -40°C to 130°C thermal cycling, 1,000-hour salt spray tests), ensuring less than 5% performance degradation within 100,000 kilometers.
