Introduction to Car Brake Shoes with Sintered Metallic Mixture
Sintered metallic brake shoes mixture is a high-performance brake shoes friction material designed for demanding automotive braking systems. This brake shoes formula combines metal powders (e.g., copper, iron, steel), graphite, and ceramic additives through powder metallurgy processes, creating a robust structure capable of withstanding extreme conditions. Below is a detailed technical overview, advantages, and storage guidelines for this advanced friction material.
Technical Parameters of sintered metallic brake shoes mixes
| Parameter | Specification |
|---|---|
| Friction Coefficient (μ) | 0.40–0.55 (stable at 0–800°C) |
| Operating Temperature | -50°C to 800°C |
| Density | 5.0–6.0 g/cm³ |
| Hardness (Rockwell) | 70–85 HRB |
| Compressive Strength | ≥150 MPa |
| Noise Level | ≤75 dB (optimized damping design) |
Note: Parameters vary based on formulations for specific vehicle types (e.g., heavy-duty trucks, high-performance cars).
Key Advantages of Sintered Metallic Brake Shoes
- Exceptional High-Temperature Performance
- The brake shoes friction materials maintain stable friction coefficients even at 800°C, preventing brake fade during prolonged downhill braking.
- Ideal for high-load scenarios such as cargo trailers and mining vehicles.
- Superior Durability
- Sintered brake shoes mixes exhibit high wear resistance, extending service life by 30–50% compared to organic or semi-metallic formulas.
- Minimal rotor/drum wear due to homogeneous material distribution.
- Optimized Braking Efficiency
- High metal content (60–80%) ensures rapid heat dissipation and consistent stopping power.
- Environmental Compliance
- Free from asbestos and copper, meeting REACH and RoHS regulations.
Packaging and Storage Guidelines
- Packaging:
- Vacuum-sealed aluminum foil bags + reinforced wooden crates for moisture and impact protection.
- Labels include part numbers (e.g., WD37-33-310) and certifications (IATF16949, ISO9001).
- Storage:
- Temperature: 5–35°C; Humidity: ≤50%.
- Avoid stacking over 5 layers to prevent deformation.
Applications
This brake shoes formula is widely used in:
- Heavy-duty vehicles (e.g., Volvo FH, Mercedes Actros).
- High-performance cars requiring aggressive braking.
- Industrial machinery with frequent stop-start cycles.
By integrating advanced powder metallurgy and optimized brake shoes mixture designs, sintered metallic brake shoes deliver unmatched reliability for extreme braking scenarios.
