 When it comes to gears, many people in the industry will compare powder metallurgy gears with machined gears, and discuss which gear produced by the two processing techniques has better performance. 　　

1: Ordinary atomized powder, the density is above 6.9, and the quenching hardness can be controlled to about HRC30. 　　

2: General pre-alloyed powder (AB powder), density above 6.95, quenching hardness can be controlled to about HRC35. 　　

3: High pre-alloyed powder (AE powder), density above 6.95, quenching hardness can be controlled to about HRC40

What are the advantages of powder metallurgy gears

1: The powder metallurgy gear itself has very good running-in performance, which can ensure long-lasting silence during use.

2: Powder metallurgy gear processing has obvious cost Mechanical structure series advantages and higher production efficiency than traditional gear hobbing technology.

3: The production cost of powder metallurgy gears is low, and it can be formed at one time, and there is no need to process the gears after forming.

4: The utilization rate of powder metallurgy gear materials is high, which is very suitable for the utilization of steel resources.

5: The density and material of the powder metallurgy gear are stable, and the tensile strength and compressive strength will be very good.

6: The powder metallurgy gear parts have good dimensional consistency, stability and high precision.

7: Powder metallurgy press forming (p/m) adopts mold forming, which can achieve complex-shaped gears that cannot be produced by machining. 8: Powder metallurgy gears can be mass-produced and processed, which greatly reduces gear production costs and has higher efficiency.
