Introduction to Motorcycle Brake Shoes Sintered Metallic Mixture
Motorcycle brake shoes sintered metallic mixtures are high-performance brake shoes friction materials designed for aggressive braking scenarios in two-wheeled applications. Combining sintered metal powders (e.g., iron, copper, and steel) with specialized binders, this brake shoes formula ensures exceptional thermal resistance, wear durability, and consistent friction output. Below is a detailed breakdown of its technical specifications, advantages, and storage guidelines.
Technical Parameters
The table below outlines the critical properties of sintered metallic brake shoes mixes:
| Parameter | Specification | Remarks |
|---|---|---|
| Metallic Content | 60-75% (Iron, Copper, Bronze) | Optimized heat dissipation |
| Density | 3.0-3.5 g/cm³ | High-strength, compact design |
| Friction Coefficient (μ) | 0.38-0.48 (Dry) | Stable under high-speed braking |
| Operating Temperature | -30°C to 550°C | Resists thermal fade in urban/off-road conditions |
| Compressive Strength | ≥280 MPa | Withstands abrupt hydraulic pressure |
| Wear Rate | ≤0.4 cm³/MJ | 30% lower than organic counterparts |
| Shore Hardness | 65-80 Shore D | Ideal for motorcycle drum/disc contact |
Key Advantages
- High-Temperature Stability
The brake shoes mixture maintains consistent friction even during prolonged downhill braking or stop-and-go traffic, thanks to sintered metals’ superior thermal conductivity. - Enhanced Durability
Reinforced with steel fibers, the brake shoes friction materials withstand abrasive road debris and high-frequency braking cycles, ideal for sport or adventure motorcycles. - Low Noise and Vibration
Graphite and ceramic additives in the brake shoes formula dampen high-frequency vibrations, reducing squeal common in wet conditions. - Rapid Bed-In Performance
Pre-sintered surfaces achieve optimal friction within 50-100 km, minimizing break-in time. - Compatibility
Designed for seamless integration with cast iron drums or composite discs, ensuring OEM and aftermarket adaptability.
Storage and Packaging
- Moisture Control: Vacuum-sealed in anti-corrosion aluminum foil bags to prevent oxidation of metallic components.
- Temperature: Store in dry environments (10°C–35°C); avoid freezing to preserve binder integrity.
- Stacking: Limit to 6 layers to prevent deformation of friction linings.
- Shelf Life: 18 months in unopened packaging; re-seal after partial use.
Application of Brake Shoes Mixes
The brake shoes mixes are manufactured via high-pressure sintering (15–25 MPa) at 800°C–1000°C, ensuring metallurgical bonding between particles. Post-production, they undergo rigorous testing for shear strength (≥3.5 MPa) and thermal shock resistance (100 cycles at 550°C). Customizable formulations allow adjustments in metallic ratios to suit racing, touring, or commuter motorcycles.
By leveraging sintered metallurgy and precision engineering, this brake shoes mixture delivers unmatched reliability and safety for motorcycles navigating diverse terrains and demanding braking conditions.
