|---|---|
| Friction Coefficient (μ) | 0.45–0.55 (stable up to 700°C) |
| Operating Temperature | -40°C to 700°C |
| Material Composition | Brake shoes friction materials (high-density steel fibers, copper-free metallic particles, ceramic modifiers, and thermoset resins) |
| Thickness Range | 12–18 mm (customizable for heavy-duty axles) |
| Noise Level | <80 dB (optimized for low-vibration operation) |
Key Advantages
- Exceptional Heat Resistance:
- The Brake Shoes Formula maintains consistent friction performance at temperatures up to 700°C, minimizing brake fade and rotor wear during prolonged downhill braking.
- Ceramic modifiers enhance thermal conductivity, rapidly dissipating heat to prevent brake system damage.
- Extended Service Life:
- High-density Brake Shoes Mixes reduce wear rates by 40–50% compared to standard metallic formulations, ideal for fleets requiring reduced maintenance downtime.
- Heavy-Duty Durability:
- Reinforced steel fibers and copper-free metallic particles ensure structural integrity under high-load scenarios, such as fully loaded trailers or off-road terrain.
- Environmentally Compliant:
- Free from copper and asbestos, aligning with global regulations (e.g., U.S. Copper-Free Initiative and EU REACH).
Packaging and Storage
- Rust Prevention: Treated with high-temperature anti-corrosion coatings to withstand humid or saline environments during transit.
- Packaging:
- Individually vacuum-sealed in moisture-resistant foil.
- Stacked in reinforced wooden crates with desiccant packs for bulk shipments.
- Storage Conditions:
- Store in dry, well-ventilated areas (humidity <50%) at 0–30°C.
- Avoid stacking above 2 meters to prevent material deformation.
Applications
Designed for:
- Long-haul trucks and freight carriers.
- Mining and construction machinery.
- Emergency vehicles requiring fail-safe braking.
The HD Metallic Formula’s brake shoes friction materials meet ISO 9001, SAE J661, and ECE R90 standards, ensuring compliance with global safety and performance benchmarks.
