🌟 About Pyrite Sulfide Powder For Brake Pads
Pyrite Sulfide Powder For Brake Pads, processed from natural pyrite (Pyrite, FeS₂) through precise purification and ultra-fine grinding, is the “performance core” of friction materials in braking systems. Leveraging the advantages of natural sulfide components in pyrite, it provides brake pads with stable friction performance, excellent wear resistance, and reliable high-temperature stability. It is a cost-effective alternative to traditional artificially synthesized sulfides.

🧪 Core Advantages: From Nature, Better Than Synthesis

• Stronger Compatibility of Natural Components: The natural sulfide combination in pyrite (FeS₂ and associated sulfides) has better compatibility with brake pad friction materials (resins, metal fibers, fillers, etc.). After mixing, it is not prone to delamination or performance fluctuations, ensuring the overall quality stability of brake pads.
• Balanced Friction Performance: Within the wide temperature range of -30℃ to 550℃, the friction coefficient stably remains at 0.38 – 0.42. It avoids excessively long braking distances caused by low coefficients and prevents brake noise or jitter caused by high coefficients, adapting to braking needs under various road conditions.
• Dual Benefits of Wear Resistance and Protection: With a Mohs hardness of 3.0 – 3.5, the particles can provide braking force through moderate friction without excessive wear on the brake disc, extending the collaborative service life of brake pads and discs.
• Excellent High-Temperature Anti-Fade Ability: Based on the thermal stability of pyrite sulfides, in high-temperature environments generated by continuous braking (such as long downhill or high-speed emergency braking), it is not easy to decompose or oxidize, effectively inhibiting “thermal fade” and ensuring braking safety under extreme working conditions.

🔍 Production Process & Quality Control
Our pyrite raw materials are selected from high-quality pyrite veins. The product quality is ensured through strict processes:

Multi-Stage Inspection: Each batch of products undergoes friction coefficient testing, impurity content detection, and high-temperature stability verification, with third-party inspection reports available upon request.

Magnetic Separation + Flotation Purification: Remove non-sulfide impurities (such as quartz, clay) in pyrite to ensure the total sulfide content ≥97%.

Ultra-Fine Grinding & Classification: Use airflow grinding technology to control the particle size within 5 – 45μm, with a uniformity rate of over 95%, ensuring full contact with other friction materials during mixing.

🚗 Application Scenarios

• Passenger Vehicles: Suitable for family cars, SUVs, and new energy vehicles, ensuring stable braking during daily commuting, highway driving, and emergency situations.
• Commercial Vehicles: Ideal for trucks, buses, and vans with heavy loads, resisting wear caused by frequent braking and maintaining reliable performance during long-distance transportation.
• Two-Wheelers: Applicable to motorcycles and electric bikes, adapting to the lightweight characteristics of their brake systems while ensuring braking efficiency.

📦 Packaging & Storage

• Packaging: 20kg composite paper bags (with moisture-proof lining) for small batches, 1000kg bulk bags (with pallets) for large orders, both designed to prevent moisture and leakage during transportation.
• Storage: Keep in a dry and ventilated warehouse, avoid direct sunlight and rain. Do not store with strong acids or oxidants. The shelf life is 18 months when unopened; after opening, seal the remaining product promptly.
