Product Advantages

1. Multi‑spec cast‑iron material to match diverse operating conditions

   Built from grey iron, high‑carbon cast iron, G3000, GG15HC, DIN and SAE grade materials. Different metallurgical formulas strike varied balance among thermal conductivity, noise control and mechanical strength. It covers daily commuter cars, family SUVs and light commercial vehicles, meeting both cost‑efficient replacement and high‑performance aftermarket requirements.

2. Full‑range certification to smooth global trade access

   Complies with IATF‑16949, ISO14001, ISO45001, ECE R90 and AMECA standards. Authorized third‑party testing validates anti‑fatigue property, burst resistance and dimensional stability. Complete certification documents support customs clearance for different overseas regions, lowering trade risks for distributors.

3. Turning‑grinding combined processing for reliable braking comfort

   Precision turning shapes the overall contour, followed by fine surface grinding. Strictly controls disc run‑out, parallelism and thickness tolerance. It effectively avoids steering shake, pedal pulsation and abnormal noise under frequent braking, and fits seamlessly with original caliper and hub assembly.

4. Flexible anti‑rust options for complex logistics and usage scenarios

   Anti‑rust oil, paint, protective coating and zinc‑dust treatment are all available options. These surface protections defend rotors against corrosion risk from long‑time ocean shipment, humid storage environment and rainy road conditions. Buyers can select treatments according to local climate and inventory cycle.

5. Diversified surface finishes for differentiated product lines

   Available in grey, black, raw metallic and gold surface options. Apart from basic replacement demand, these stylish appearances help buyers develop high‑end private‑label retail lines to capture consumers who focus on both function and outward look.

6. Optimized heat dissipation to extend service cycle of brake assembly

   Well‑designed internal air channel speeds heat dissipation during continuous braking and downhill driving. It suppresses hot spot, thermal deformation and crack occurrence. Reasonable temperature control also reduces uneven wear of supporting brake pads for longer overall brake‑system lifespan.

7. OE‑matching dimension for direct fit‑on installation

   Mounting surface, bolt hole position and overall size strictly reference original component specifications. No modification needed at repair shops, ensuring accurate assembly for matched vehicle models.

Raw Material & Manufacturing Process

Material Parameters

‑ Casting blank: Grey iron / High‑carbon cast iron (G3000, GG15HC, DIN, SAE grade). Stable internal structure delivers good vibration

‑absorbing performance, wear resistance and heat conduction capacity, reducing brake squeal probability. 

‑ Anti‑rust treatment: Oiled, painted, coated, zinc‑dust optional 

‑ Surface color: Grey, black, metal natural tone, gold

Production Steps

1. Melting & ingredient adjustment: Raw iron is molten, chemical composition fine‑tuned to satisfy target material grade.

2. Precision casting: Form brake disc blanks; process monitoring prevents shrinkage cavity, porosity and other internal casting defects.

3. Stress‑release annealing: Heat treatment eliminates residual stress generated in casting phase to mitigate thermal deformation risk in service.

4. Blank inspection: Visual inspection and non‑destructive testing eliminate defective blanks before machining.

5. Turning process: Rough and finish turning for hub surface, outer circle and inner structure.

6. Double‑sided grinding: Fine grinding guarantees parallelism and uniform thickness.

7. Hole machining: Bolt holes and locating holes are processed as per OE drawings.

8. Surface anti‑rust treatment: Apply customer‑specified anti‑corrosion solutions.

9. Final quality inspection: Run‑out test, dimensional measurement and appearance check; sampling test for certification requirements.

Packaging Choices

‑ Single‑unit protection: Protective wrapping film to prevent scratch and collision damage.

 ‑ Custom retail carton: Support private‑label custom printing, mark OE number and vehicle application information. 

‑ Outer shipping package: Individual box, carton, pallet or bulk packing. Export‑grade heavy‑duty packaging adapts to long‑distance sea freight and mixed container loading.

Commercial Value for Global Buyers

Overseas Trade Support

Complete certification documents simplify customs clearance. The product solves common aftermarket pain points such as brake shaking, thermal deformation, premature rust and poor fitting, helping importers reduce after‑sales pressure and return ratio.

Workshop‑friendly Installation

Direct OE replacement improves fitting efficiency in repair shops. Good compatibility with mainstream aftermarket brake pads facilitates daily maintenance work.
