Introduction to Car Brake Shoes with Sintered Mixture
Sintered brake shoes mixture is a high-performance brake shoes friction material widely used in automotive braking systems. This brake shoes formula combines metal powders (e.g., copper, iron, graphite) with ceramic additives under high-temperature sintering, creating a durable and heat-resistant composite ideal for demanding braking conditions. Below is a detailed technical overview, advantages, and storage guidelines for sintered brake shoes mixes.
Technical Parameters of sintered brake shoes mixture
| Parameter | Specification |
|---|---|
| Friction Coefficient (μ) | 0.40–0.55 (stable at 0–800°C) |
| Operating Temperature | -30°C to 800°C |
| Density | 3.2–4.0 g/cm³ |
| Compressive Strength | ≥150 MPa |
| Shear Strength | ≥4.0 MPa |
| Noise Level | ≤75 dB (low-vibration design) |
Note: Parameters vary based on formulations for specific vehicle models (e.g., sedans, SUVs).
Advantages of Sintered Brake Shoes Mixes
- Exceptional Durability
- The brake shoes friction materials exhibit high wear resistance, extending service life by 20–30% compared to organic alternatives.
- Stable friction performance at extreme temperatures prevents brake fade during prolonged use.
- Environmental Compliance
- Free from asbestos and restricted heavy metals (e.g., chromium VI), aligning with global standards like REACH and RoHS.
- Low dust emission reduces environmental contamination.
- Enhanced Safety
- Optimized brake shoes formula ensures rapid heat dissipation, minimizing thermal deformation of brake drums.
- High shear strength (≥4.0 MPa) prevents delamination under heavy loads.
- Cost Efficiency
- Reduced maintenance frequency due to extended lifespan.
Packaging and Storage Guidelines
- Packaging:
- Vacuum-sealed moisture-proof bags + reinforced cardboard boxes for bulk transport.
- Labels include part numbers (e.g., WVA29035, 29100) and certifications (IATF16949, ISO 9001).
- Storage:
- Temperature: 10–30°C; Humidity: ≤60%.
- Avoid exposure to corrosive chemicals or direct sunlight.
Applications
The brake shoes mixes are ideal for:
- Passenger vehicles (e.g., Toyota Camry, Honda CR-V).
- Commercial vehicles requiring high-load braking (e.g., delivery vans).
This sintered brake shoes mixture balances robustness, safety, and eco-friendliness, making it a leading choice for modern automotive braking systems. For OEM customization, refer to supplier technical catalogs.
