Introduction to Truck Brake Linings Sintered Metallic Mixture
Truck brake linings sintered metallic mixtures are high-performance brake linings friction materials designed for extreme-duty applications, combining metallic powders, binding agents, and reinforcing additives through a sintering process. This brake linings formula ensures exceptional thermal stability, wear resistance, and consistent braking efficiency under heavy loads and high temperatures. Below is a detailed overview of their technical specifications, advantages, and storage protocols.
Technical Parameters
The table below summarizes key properties of sintered metallic brake linings mixes:
| Parameter | Specification | Remarks |
|---|---|---|
| Metallic Content | 60-80% (Iron, Copper, Bronze) | Enhances heat dissipation and structural integrity |
| Density | 2.8-3.5 g/cm³ | Optimized for high-pressure resistance |
| Friction Coefficient (μ) | 0.40-0.50 (Dry) | Stable performance across speed gradients |
| Operating Temperature | -50°C to 800°C | Resists thermal fade and glazing |
| Compressive Strength | ≥350 MPa | Withstands extreme hydraulic pressures |
| Wear Rate | ≤0.3 cm³/MJ | Extended service life in harsh conditions |
| Shore Hardness | 70-85 Shore D | Ensures firm drum contact and noise control |
Key Advantages
- Superior Thermal Management
The sintered brake linings mixture leverages metallic alloys (e.g., iron-copper matrices) to dissipate heat rapidly, minimizing brake fade during prolonged downhill braking. - Enhanced Durability
High metallic content and sintering process reduce wear rates by 30-40% compared to organic counterparts, ideal for mining and long-haul trucks. - Consistent Friction Output
The brake linings formula maintains a stable friction coefficient even at elevated temperatures, ensuring predictable stopping power. - Corrosion Resistance
Sintered materials inherently resist moisture-induced oxidation, critical for off-road and marine environments. - Low Noise and Vibration
Precision-engineered porosity in the brake linings mixes dampens vibrations, reducing squeal.
Storage and Packaging
- Moisture Protection: Packaged in vacuum-sealed, desiccant-lined containers to prevent oxidation of metallic components.
- Temperature Limits: Store in environments below 35°C to avoid binder degradation.
- Stacking: Maximum 4 layers to prevent deformation of pre-molded linings.
- Shelf Life: 18 months in unopened packaging; post-opening, use within 6 months.
Application of Brake Linings Mixes
The brake linings friction materials are sintered under high temperatures (900-1100°C) and pressures (20-40 MPa), ensuring a dense, homogenous structure. Post-production, they undergo rigorous testing for shear strength (≥4.0 MPa) and thermal shock resistance. Customized formulations are available for OEMs requiring tailored wear rates or noise profiles.
This sintered metallic technology bridges the gap between performance and longevity, making it a preferred choice for commercial vehicles operating in the most demanding environments.
