The invention belongs to the technical field of powder metallurgy, and discloses a powder metallurgy material for a brake magnetic seat and a preparation method of the brake magnetic seat. The powder metallurgy material comprises 100 parts of composite iron powder, 1-5 parts of graphite and 0.1-2 parts of a lubricant, wherein the composite iron powder comprises the following components in percentage by mass: 0.5-2.4% of silicon, 0.08-0.3% of phosphorus and the balance of iron and inevitable impurities. The magnetic conductivity of the magnetic seat is improved by using a small amount of phosphorus element, and the toughness and processability of the material are improved by using the composite iron powder with low silicon content, so that the material not only has good magnetic property, but also has good mechanical property. The powder metallurgy technology is adopted, the magnetic base is prepared in an integrated forming mode, the steps of material mixing, pressing, presintering, sintering and hot isostatic pressing are included, and the prepared magnetic base is high in mechanical property, good in magnetic conductivity, light, resistant to abrasion, simple in preparation step and suitable for industrial batch production.

The invention discloses an anti-cracking brake drum and a manufacturing method thereof. The anti-cracking brake drum comprises a brake drum body. The brake drum body comprises a top face and a cylindrical face vertically extending downward in the circumferential direction of the top face. A plurality of thread-shaped spiral bars are arranged on the inner wall face of the cylindrical face. A connecting bar is arranged between every two adjacent spiral bars. The spiral bars at the starting point and the end point of the inner wall face of the cylindrical face are linear annular sections. The spiral bars are combined on the cylindrical face of the brake drum in a pouring mode, and the spiral bars of the brake drum and the cylindrical face of the brake drum are an integrally-formed part, so that the spiral bars and the cylindrical face do not fall off due to thermal expansion and contraction, the stability property of the brake drum is guaranteed, and the brake drum is prevented from problems such as cracking.
