Figure 3 pictures some representative sizes of powder cores. An alloy material is first ground to a fine powder. The powder is mixed with an insulating material which separates each particle from the next, thus increasing resistivity. Next, the powder is pressed into toroidal shapes. The cores are annealed, painted, and then tested for ...

Different density and size ratios were investigated to observe the limit up to which good mixing takes place. Density differences between the binary powders were varied from 1.5 up to 16.4. The range of size ratio investigated was from 1.96 up to 15.73. Results indicate that powders mixed very well up to a particle size ratio of 4.45.

At the bottom of the powder column, the rotor slices through the powder to avoid hard compact. The rotor then moves up through the powder at 20 mm/s twice followed by two cycles of 50 mm/s, two cycles at 100 m/s, and two cycles at 10 mm/s. The analysis is performed on both the positive (force vs distance) and negative areas. The average is ...

The mesh size of this aluminum powder is -200 vs. the -300 mesh for the other metal powders and gives a better cold cast effect compared with other mesh size powders that we tested. Polished castings are brighter vs. castings made using nickel/silver powder, which has more of an antique metal look.

A powder's mesh size can at times be somewhat confusing. A -6 mesh powder contains particles that pass through a 6 mesh screen. A -6 mesh powder has particles that measure less than 3360 microns. A powder that is -325 mesh has particles that measure less than 44 micron. As you can see, the larger the mesh number the smaller the particle size ...

The number of openings is the mesh size. So a 4 mesh screen means there are four little squares across one linear inch of screen. A 100 mesh screen has 100 openings, and so on. Note, therefore that as the number describing the mesh size increases, the particle size decreases. Higher numbers = finer powder.
