The invention relates to a guider of an automobile shock absorber and a manufacturingmethod thereof, and belongs to the field of automobile spare parts. The guider of the automobile shock absorber is formed by hot-pressing and sintering alloy powder, ceramic powder, pore-foaming agents and binders, wherein the mass ratio of the alloy powder, the ceramic powder, the pore-foaming agents and the binders is 100 to 40-90 to 0.3-1 to 1-5; the alloy powder is composed of, by weight, 2-8% of reduction copper powder, 2-8% of graphite powder, 0.3-2% of phosphorization iron powder, 0.5-3% of manganese sulfide, 3-12% of chromium powder, 0.5-3% of nickel powder and the balance iron powder. The invention further provides the manufacturingmethod of the guider of the automobile shock absorber. According to the manufacturing method, material for manufacturingthe guider of the automobile shock absorber is reasonably selected, the alloy powder and the ceramic powder are selected for manufacturing porous material, multi-stage high-temperature sintering and low-temperature tempering are adopted after forming, and therefore the weightof the guider of the automobile shock absorber is lowered, the comprehensive property of the guider is improved, the mechanical property of the guider is excellent, the strength, the rigidity, the wear resistance and the high temperature resistance of the guider are good, the cost is low, the use efficiency of the guider is improved, and the service life of the guider is prolonged.
