Introduction to Car Brake Pads with Semi-Metallic Formula
Semi-metallic brake pads employ a hybrid Brake Pads Mixture that combines metallic reinforcements with organic compounds, striking a balance between durability and performance. This Brake Pads Formula integrates 30%–65% steel fibers, copper particles, and graphite into its Brake Pads Friction Materials, making it ideal for high-stress driving conditions.

Key Advantages
- Enhanced Heat Dissipation
- The Brake Pads Mixes leverage metallic components to rapidly dissipate heat, reducing brake fade during prolonged use.
- Maintains 85% friction efficiency at 400°C.
- Durability & Cost Efficiency
- Steel fibers in the brake pads friction materials extend service life by 25% compared to non-metallic variants.
- Lower replacement frequency reduces long-term costs.
- Wide Application Range
- Optimized brake pads formula suits SUVs, trucks, and performance vehicles due to high shear strength (≥75 MPa).
Storage & Packaging Guidelines
- Packaging:
- Individually wrapped in anti-corrosion VCI paper.
- Stacked in reinforced cartons with “↑THIS SIDE UP” labels.
- Storage:
- Temperature: 5°C–35°C in dry environments (humidity <65% RH).
- Avoid direct sunlight to prevent resin degradation.
Formula Composition
The semi-metallic brake pads mixture comprises:
- Metallic Components: Steel wool (35%), copper flakes (10%)
- Friction Modifiers: Graphite (12%), cashew dust (8%)
- Binders: Phenolic resin (15%)
This brake pads formula ensures stable friction output while minimizing rotor wear and noise generation.
