Introduction to Truck Brake Linings Metallic Mixture
Truck brake linings metallic mixtures are high-performance brake linings friction materials designed for heavy-duty vehicles, combining metallic elements (e.g., steel, copper) with binding agents and heat-resistant additives. This brake linings formula ensures exceptional durability, thermal stability, and consistent braking performance under extreme conditions. Below is a detailed overview of its technical specifications, advantages, and storage guidelines.
Technical Parameters
The table below highlights key properties of metallic-based brake linings mixes:
| Parameter | Specification | Remarks |
|---|---|---|
| Metallic Content | 55-75% (Steel fibers, Copper particles) | Enhances heat dissipation and wear resistance |
| Density | 2.8-3.5 g/cm³ | Optimizes structural integrity and load capacity |
| Friction Coefficient (μ) | 0.38-0.48 (Dry) | Stable across speeds and temperatures |
| Operating Temperature | -40°C to 650°C | Resists thermal fade and cracking |
| Wear Rate | ≤0.6 cm³/MJ | Extended service life for high-mileage applications |
| Shore Hardness | 65-80 Shore D | Ensures compatibility with cast iron drums |

- Shelf Life: 18–24 months in unopened, original packaging .
Application of Brake Linings Mixes
The brake linings formula is molded under high pressure (10–25 MPa) and sintered to ensure adhesion between the friction layer and backing plate. Post-production testing includes thermal cycling (500+ cycles) and shear strength validation (≥4.0 MPa) to guarantee reliability .
Customizable brake linings mixes are available for OEM or aftermarket requirements, adjusting metallic ratios for specific load or climate conditions .
This advanced blend of metallic reinforcements and precision engineering ensures optimal braking efficiency and safety for commercial vehicles operating in demanding environments.
