Half metallic brake pads are mainly composed of 30% -65% metallic materials such as copper and iron. The characteristics of this type of brake pad are fast heat dissipation, good high-temperature resistance, and relatively low price. However, due to the presence of metal materials, there is a significant amount of noise generated during braking, and the wear on the brake discs is also significant. In addition, the friction coefficient of these brake pads is generally 0.38, and their service life is relatively short.

There are two types of metal materials: iron and copper. There is a commonly known type of wear-resistant iron. This type of metal sheet is relatively black and there are no visible spots. There is also a type of copper powder. On the surface of the brake pads, some brass or purple copper metal blocks or small particles can be seen.
