Sinter Parts or Powder Metallurgy
	Copper-based sinter parts , iron-based sinter parts, iron-based sinter parts Copper-based sinter parts powder metallurgy for auto parts and machinery parts. OEM service is available. Iron-based sinter parts and copper-based sinter parts. Sintered Parts are widely used for machinery, house hardware, garden, agricultural machines, electrical power tools and etc. The so called powder metals have 3 major advantages: (A) high precision due to mold-based production (B) low price due to its inherent feature of automation for mass production, and (C) flexibility of material composition due to wide variety of powder formula on Fe-Cu-Ni alloy. Besides, if the bearings and bushes are made of metallurgical metals, then it becomes free of maintenance since the sintered metals have the inherent porosities for oil impregnation which has been well done as soon as the sintered bushes, sintered gears or sintered parts are manufactured. In addition, the mechanical parts such as gears, pivots and pinions can also be produced by metallurgy because the strength can be enhanced by heat treatment and adding nickel into the powder formula. Further more, more than 200 types of vehicle parts and motorcycle parts, i.e., metallurgical parts, are made of sintered metals. This implies that the safety of long-term operation for sintered parts (or powder parts ) is pretty ensured. At last, in order to improve the ductility and elasticity of sintered metals (or sinter metal, sinter parts, sinter bush, sinter gear ) in machinery, the alloy that includes copper and iron becomes the main stream. This is only available by employing the technology of powder metallurgy and sintering
