Introduction to Car Brake Shoes with Semi-Metallic Mixture
Semi-metallic brake shoes mixture is a high-performance brake shoes friction material widely used in modern automotive braking systems. This brake shoes formula combines metal fibers (e.g., steel, copper) with organic binders and friction modifiers, offering a balance of durability, heat resistance, and braking efficiency. Below is a detailed technical overview, advantages, and storage guidelines for this advanced friction material.
Technical Parameters of semi-metallic brake shoes mixes
| Parameter | Specification |
|---|---|
| Friction Coefficient (μ) | 0.38–0.48 (stable at 0–800°C) |
| Operating Temperature | -40°C to 800°C |
| Density | 2.5–3.0 g/cm³ |
| Thickness | 6–18 mm (customizable) |
| Shear Strength | ≥4.0 MPa |
| Noise Level | ≤75 dB (moderate-noise design) |
Note: Parameters vary based on formulations for specific vehicles (e.g., sedans, SUVs, light trucks).
Advantages of semi-metallic brake shoes mixture
- Superior Heat Dissipation
- High metal content (30–60%) enables rapid heat transfer, reducing brake fade during prolonged use.
- Stable friction performance at extreme temperatures, ideal for high-load or frequent braking scenarios.
- Enhanced Durability
- Reinforced with steel fibers, the brake shoes friction materials exhibit exceptional wear resistance, extending service life by 20–30% compared to organic alternatives.
- Cost-Effectiveness
- Lower production costs than ceramic or NAO mixes, making it a popular choice for mid-range and commercial vehicles.
- Adaptability
- Compatible with drum brake systems in vehicles like Ford Transit, Chevrolet Silverado, and Toyota Hilux.
Packaging and Storage Guidelines
- Packaging:
- Vacuum-sealed aluminum foil bags + reinforced corrugated boxes to prevent moisture ingress.
- Labels include part numbers (e.g., WVA29035, 29101) and certifications (ISO 9001, ECE R90).
- Storage:
- Temperature: 10–35°C; Humidity: ≤65%.
- Avoid stacking heavy items on packaged units to prevent deformation.
Applications
The brake shoes formula is ideal for:
- Passenger cars requiring high thermal stability (e.g., SUVs, pickup trucks).
- Commercial vehicles operating in mountainous or urban stop-and-go traffic.
By integrating robust brake shoes mixes with optimized metal-organic ratios, this semi-metallic solution ensures reliable braking performance across diverse driving conditions. For OEM specifications or customization, consult supplier technical datasheets.
