■ Powder metallurgy features 

(1) Mass production is possible and uniform quality can be obtained within the same lot.

(2) It has good surface condition and excellent dimensional accuracy.

(3) Machining can be omitted, which not only significantly lowers the price, but also saves materials.

(4) Low energy consumption in manufacturing process.

⇒ There is no need to raise the temperature to the melting point in the manufacturing process (sintering temperature: 70% to 80% of the melting point), so energy consumption in the manufacturing process is low.

(5) Easy to design alloy.

⇒ Special alloys that cannot be made by conventional melting methods can be freely created due to differences in melting limit, specific gravity, and melting point of alloy components.
