An artifical granitic or marmoreal mechanical fitting and manufacturing method thereof are disclosed. The artifical granitic or marmoreal mechanical fittings is composed of (wt.%) 80%-93% of aggregate and 20%-7% of bonding material and is produced by a process including mixing, filling of mould, densifying etc. Therein, the aggregate is natural granitic or marmoreal grain sized of 0.01-25mm. Vibration damping of the invented mechanical fittings is larger and lower cost than the prior fittings, and the mechanical fittings is widely used.
