Introduction to Semi-Metallic Formula Truck Brake Linings
Semi-metallic truck brake linings are engineered with a balanced Brake Linings Formula that combines metallic and non-metallic components to deliver robust braking performance, thermal resilience, and extended service life. The optimized Brake Linings Mixture integrates steel fibers, copper particles, ceramic modifiers, and organic binders, making it ideal for heavy-duty applications requiring high friction stability and durability.
Technical Parameters
| Parameter | Value/Range |
|---|---|
| Friction Coefficient (μ) | 0.38–0.48 (dry conditions) |
| Operating Temperature | -50°C to 600°C |
| Density | 2.5–3.0 g/cm³ |
| Compressive Strength | ≥90 MPa |
| Metallic Content | 30–50% (by weight) |
| Porosity | 10–18% |
| Thickness | 12–25 mm (customizable) |
Key Advantages
- High Friction Stability
- The Brake Linings Friction Materials leverage steel fibers and copper particles to maintain consistent friction levels across extreme temperatures, reducing brake fade during prolonged use.
- Enhanced thermal conductivity from metallic components improves heat dissipation, ensuring reliable performance in heavy-load scenarios.
- Durability & Wear Resistance
- Semi-metallic Brake Linings Mixes exhibit 20–30% longer lifespan compared to non-metallic alternatives due to reduced abrasion on brake drums and rotors.
- Reinforced structural integrity from metallic fibers enhances resistance to cracking under high-stress conditions.
- Noise and Vibration Control
- Advanced brake linings formula incorporates dampening agents (e.g., rubberized polymers) to minimize high-frequency noise, achieving 10–15 dB lower sound levels than traditional metallic linings.
- Environmental Compliance
- Free from asbestos and hazardous heavy metals, meeting global standards like EU REACH and US EPA regulations.
Storage & Packaging
- Packaging:
- Sealed in moisture-resistant polyethylene bags, with shock-absorbent wooden crates for bulk shipments (up to 12,000 kg per batch).
- Barcoded labeling for traceability and OEM/aftermarket customization.
- Storage Conditions:
- Store in a cool, dry environment (humidity <55%, temperature 5–35°C).
- Avoid stacking pallets higher than 2 meters to prevent deformation.
Applications
Suitable for long-haul trucks, construction vehicles, and buses operating under high-stress conditions.
By harmonizing metallic strength with advanced brake linings friction materials, semi-metallic formulas offer a cost-effective solution for demanding braking environments.
