184x6mm Sintered Iron Friction Disc for Racing Clutch
I. Core Introduction to Material of Iron-Based Sintered Friction Discs
1. Basic Formula System
The substrate is mainly composed of reduced iron powder, with the following additives:
Friction enhancers: alumina, zircon sand, silicon-carbon hard particles, for boosting high-temperature friction coefficient
Lubricating components: graphite, tin sulfide, leaded / lead-free sulfides, to prevent high-temperature seizure
Alloy additives: copper, nickel, chromium, for improving mechanical strength and thermal stability
2. Core Performance (Exclusive Advantages for Racing Applications)
Excellent High-Temperature Resistance Withstands temperatures of 700–850°C for short durations. It resists heat fade under harsh conditions such as aggressive launches, consecutive gear shifts and long-distance track braking. By contrast, copper-based discs only endure a maximum of 500–600°C and perform inferiorly to iron-based ones under heavy track loads.
High & Stable Friction Coefficient Dry friction coefficient ranges from 0.45 to 0.65. It delivers strong grip during launch, transmits high horsepower and high torque, making it ideal for modified large-displacement and turbocharged race cars.
Impact Resistance & Heavy Sliding Wear Resistance Resists slipping and glazing under frequent half-clutch engagement and high-RPM launches, suitable for drifting, circuit racing and drag racing.
Disadvantages
High hardness accelerates wear of pressure plates and flywheels; reinforced racing-grade metal flywheels are required as matching parts.
Poor low-speed smoothness, prone to shuddering and jerking during stop-and-go traffic.
Generates more noise than copper-based counterparts.
II. Applicable Scenarios
Circuit race cars, drift vehicles, modified drag racing cars, heavy-duty racing motorcycles
Racing single-plate / multi-plate metal clutches (standard fitment for reinforced racing clutch kits)
III. Comparison with Sintered Copper Friction Discs
| Item | Racing Sintered Iron Disc | Sintered Copper Disc |
|---|---|---|
| Maximum Temperature Resistance | 700~850°C | 500~600°C |
| Friction Coefficient | Higher, powerful instantaneous output | Moderate, smooth power delivery |
| Counterpart Component Wear | Accelerated wear on flywheels / pressure plates | Less abrasion to steel mating parts |
| Applicable Working Conditions | Aggressive track launches, sustained heavy loads | Construction machinery, heavy-duty wet clutches, dual-purpose street & mild racing vehicles |
| Smoothness | Poor, obvious shudder at low speeds | Superior, suitable for daily commuting |
