The so-called brake drum is a part of the drum brake system. When braking, the piston applies pressure to the two pairs of half moon shaped brake shoes, making them tightly adhere to the inner wall of the drum chamber, thereby generating friction to stop the rotation of the wheels
The material of the brake drum is generally HT200-300 (i.e. gray cast iron), with the main matrix structure being pearlite and a small amount of ferrite and cementite. The graphite is mainly A-grade, with a long sheet shape and a length grade of 4-6, which plays a role in heat dissipation, increasing friction performance, and reducing brake noise.
The production process of brake drum blanks is casting, and the main raw materials required are generally pig iron, scrap steel, and recycled iron. At the same time, some alloys such as Cu, Cr, etc. are added to improve the performance of the castings
