Matrix-body
"Matrix" is a very hard, rather brittle composite material comprising tungsten carbide grains metallurgically bonded with a softer, tougher, metallic binder.
Matrix is desirable as a bit material, because its hardness is resistant to abrasion and erosion.
It is capable of withstanding relatively high compressive loads, but, compared with steel, has low resistance to impact loading.
Matrix is relatively heterogeneous, because it is a composite material.
Because the size and placement of the particles of tungsten carbide it contains vary (by both design and circumstances), its physical properties are slightly less predictable than steel.
Matrix body bits are manufactured by mold process.
he tungsten carbide and binder materials are arranged into the mold.
The mold get placed in to the furnace for certain period of the time and materials are cooked to certain temperature. The mold later cooled down and broken to remove the unfinished matrix bit.
