FG type micron diamond
Mypolex polycrystalline diamond, standard size range
Appearance
FG diamond is dark gray to black in color.
Particle structure
FG diamond is a polycrystalline diamond,
formed by explosion synthesis. Each diamond particle consists
of countless microcrystallites, about 20 nanometers in
size. Polycrystalline diamond features no cleavage planes,
which makes the particles tougher, compared to monocrystalline
particles.
Characteristics
FG diamond is particularly suited for high-performance
lapping applications.
Thanks to its polycrystalline structure without cleavage
planes, FG diamond is considerably stronger than monocrystalline
diamond. This allows for higher process pressures and
thus increased material removal rates in lapping applications.
For final polishing steps we recommend the use of precision
graded DP type polycrystalline diamond. While DP diamond
features the same high material removal rate as FG diamond,
it produces a better surface quality.
