Conventional pressing is around 6.8.

The maximum temperature and pressure can reach 7.3.

MIM can reach 96% of the relative density (for example, the iron density is 7.9 and the product density is 7.58).

HIP, recompression, reburning or copper infiltration can all increase the density to 7.8.

Of course, these are only theoretical densities.

Due to different raw materials, different equipment, different personnel, different product structures and different molds, the actual density will be affected.

Why do you need to know this?

I work in powder metallurgy. If you don't understand anything, you can ask or add friends.
