High end and low-end brake pads: the material revolution behind the performance gap

In the automotive industry, the performance of car brake pads is crucial for driving safety, and there is a significant performance gap between high-end and low-end brake pads, with material differences being the key factor leading to this gap.

Low end brake pads: cost priority, performance compromise

Ordinary household cars and low-end models often use semi metallic materials (copper/steel fiber) or ceramic matrix composite materials, which have the advantage of low cost, but there are obvious shortcomings:

Low temperature resistance limit (≤ 500 ℃), continuous braking is prone to heat degradation, and the friction coefficient fluctuates by more than 30%;

Poor wear resistance, with a lifespan only one-third of high-end materials, frequent replacement increases hidden costs;

Weak impact resistance, unable to withstand high-frequency vibrations (>50G impact force) during rapid braking of supercars.

High end brake pads: ultimate performance, only "material" is the key

Top performance car manufacturers have almost stringent requirements for braking systems, striving to achieve a perfect integration of precise braking and ultimate handling at high speeds.

High temperature resistance (>1200 ℃), resistant to high-temperature creep impact and friction sparks of brake discs;

No thermal attenuation ensures stable performance after multiple braking cycles

Ultra long lifespan, capable of handling extreme wear and tear of high-frequency brakes during track level driving.

Only cutting-edge materials can meet these demands, and tungsten carbide is the core answer to this performance competition.

The collapse of traditional materials: why are they not compatible with high-end car models?

The following table may provide the answer

Technological innovation: the perfect partner for hot pressing molding

Chengfeng Material's tungsten carbide powder can achieve the following high-quality parameters through thermophysical ultra-high pressure atomization technology

The particle size is controllable (0.5-5 μ m can be customized) to ensure material uniformity, and the finished brake pads are delicate and do not damage the brake disc.

Oxygen content<0.1%, to avoid high-temperature oxidation failure

Perfectly integrated with nickel/cobalt based alloys, the density after hot pressing is as high as 14.8g/cm ³, and the porosity is less than 0.5%.

We have achieved stable supply for domestic high-end brake pad manufacturers, and our end products are applied to European high-end car brands such as BMW M series and other sports cars.
