Key Advantages
- Superior Heat Resistance
- The Brake Pads Mixes blend copper (45–50%), iron (30–35%), and graphite (10–15%), maintaining stable friction even at 800°C, reducing brake fade by 60% compared to organic formulas.
- Extended Service Life
- Sintered brake pads friction materials exhibit 40% lower wear rates under 30-ton payloads, validated by 100,000 km field tests.
- Enhanced Wet Performance
- Micro-porous structure in the brake pads formula improves water drainage, reducing wet-braking distance by 15% (tested at 80 km/h).
- Corrosion Resistance
- Zinc-coated steel backing plates and anti-oxidation additives prevent rust in salt-spray environments (ASTM B117 compliant).
Storage & Packaging Guidelines
- Packaging:
- Individually wrapped in anti-abrasion polyethylene film.
- Reinforced wooden crates with desiccant packs (max moisture: 5% RH).
- Storage:
- Temperature: -10°C–35°C in dry, vibration-free environments.
- Stacking limit: ≤8 layers to avoid edge chipping.
Formula Composition
The brake pads mixture comprises:
- Metallic Matrix: Copper (45–50%), iron powder (30–35%)
- Friction Modifiers: Graphite (10–15%), zirconium silicate (5–8%)
- Binders: Sintered bronze (8–10%)
- Reinforcements: Ceramic fibers (3–5%)
This brake pads formula is optimized for mining trucks, freight carriers, and other heavy commercial vehicles requiring extreme-duty braking solutions.
