Powder metallurgy material used for bearing and preparing method of material

The invention relates to a powder metallurgy material used for bearing and a preparing method of the material. The powder metallurgy material used for the bearing comprises following raw materials including, by weight part, 60 to 70 parts of Fe, 6 to 9 parts of Zn, 2 to 5 parts of Mo, 1 to 2 parts of Hf, 1 to 4 parts of Al, 3 to 6 parts of Nb, 1 to 3 parts of Dy, 2 to 4 parts of Te, 0.5 to 0.9 part of Tc, 0.2 to 0.6 part of Zr, and 0.6 to 1 part of Ce. The powder metallurgy material for a brake is higher in pressure resistance strength and hardness, the service life of the bearing can be effectively prolonged, and pressure and wear resistance strength of the bearing can be effectively improved. 本发明涉及种用于轴承的粉末冶金材料及其制备方法，用于轴承的粉末冶金材料包括如下重量份的原料：60-70份Fe、6-9份Zn、2-5份Mo、1份-2份Hf、1-4份Al、3-6份Nb、1-3份Dy、2份-4份Te、0.5份-0.9份Tc、0.2-0.6份Zr、0.6-1份Ce。本发明的制动器用粉末冶金材料，抗压强度和硬度都较高，可有效提高轴承的使用寿命和耐压耐磨强度。
