Audi Composite Aluminum Hat Brake Discs

Brake Discs Features:                                                   

•Equivalent to OE design 

•Smooth and quick stop 

•Anti-rust 

•Low noise, low dust 

•Optimal thermal performance 

•Reduces unsprung mass, improving handling, acceleration, and energy efficiency. Can cut weight by over 50% compared to cast iron.

•High thermal conductivity lowers operating temperatures and distributes heat more evenly, reducing risk of brake fade and thermal cracking.

•Surface forms a dense oxide layer that protects against rust, preventing cosmetic rust spots on the braking surface.

•Extremely hard and wear-resistant material, with service life several times longer than conventional cast iron discs.

•Provides stable and efficient braking performance, particularly under high-stress conditions, with minimal heat-related performance drop.

1. Product Overview

Classification: Brake Disc. Origin: Shandong, China. Main Market: Global market. Engineered with OE-equivalent dimensions to ensure direct bolt-on fitment, delivering smooth and quick stops with low noise and low dust.

2. Material & Standards

Material: Gray Iron, High Carbon. Strictly meets G3000, GG15HC, DIN, and SAE standards. This metallurgy provides optimal thermal performance, effectively resisting brake fade and thermal fatigue under sustained braking.

3. Precision Machining

Machining: Turning, grinding. Precision lathe turning and fine grinding guarantee flat, smooth friction surfaces and strict run-out control, ensuring consistent pedal feel and minimal vibration.

4. Anti-Rust & Finish

Anti-rust Methods: Oiled, painted, coated, zinc dust.

Color: Gray, black, metal, gold. Multiple protective finishes prevent corrosion during storage and extend service life in diverse climates.

5. Certification & Quality

Certification: IATF16949, ISO14001, ISO45001, ECE R90, AMECA. Manufactured under certified management systems with full batch traceability and rigorous testing (hardness, salt spray, thermal fatigue) for international buyers.

6. Customization & Packaging

Brand: Private label, customized label (laser marking or embossed).

Transport Package: Box, carton, pallet, bulk. Flexible packing and mixed SKU container loading supported for distributors.

7. Installation & Bedding-in

Replace in axle pairs with matching pads. Avoid hard braking for the first 300 km; gradual moderate stops ensure even pad-disc mating to maximize life and minimize noise.

8. Storage & Logistics

Store in a dry, well-ventilated warehouse away from corrosive chemicals. Use moisture-proof inner packaging and desiccants for sea freight to protect oiled or coated surfaces.

• 100% critical dimensions, runout and DTV inspection 

• Material physical and chemical inspection

• Test shear strength, compressibility, density, flatness and parallelism 

• Test performance and noise/NVH
