Hello everyone, I’m from Annat. Today, let’s explore Big Flake Graphite—a critical material in high-performance Brake Pads Mixes.
First, what defines it? Big Flake Graphite refers to graphite with a flake diameter exceeding 800 microns, and Annat’s premium grade typically ranges from 1000 to 2000 microns. Its unique layered crystalline structure is the key to its value in brake pads production.

Now, let’s dive into its core advantages in Brake Pads Friction Materials, backed by key technical data:
1. Exceptional Lubricity & Wear Resistance: The layered structure enables micro-sliding between flakes, reducing friction-induced wear. Tests show brake pads incorporating Annat’s Big Flake Graphite (at 15-20% weight ratio) have a wear rate as low as 0.3 mm/1000 km—30% lower than those using small-flake graphite. This extends brake pad lifespan significantly.

2. Stable Friction Coefficient: It maintains consistent friction even under extreme temperatures. From -40°C to 600°C, the friction coefficient only fluctuates between 0.35 and 0.45, avoiding “friction fade” at high temps or “cold grab” in low temps—critical for driving safety.
3. Superior Thermal Conductivity: With a thermal conductivity of 150-200 W/(m·K), it rapidly dissipates heat generated during braking. This keeps brake pad surface temperature 50-80°C lower than non-graphite alternatives, preventing material degradation and ensuring stable performance during continuous braking.

4. Reduced Noise & Vibration: The flake structure absorbs vibration and dampens noise. Brake pads with our graphite produce noise below 65 dB during operation, well below the industry average of 80 dB, enhancing driving comfort.
At Annat, we strictly control purity—our Big Flake Graphite has a carbon content of ≥99.5% and ash content ≤0.3%, ensuring no impurities compromise brake pad performance. It’s the ideal choice for passenger cars, commercial vehicles, and high-performance vehicles alike.
