	Density g/cm3	Hardness HRA	Bending Strength N/mm2
TYG4C	14.5-15.2	>=89.5	>=1420	High strength and impact resistance, used in drilling on mining layers.
TYG8	14.5-14.9	>=89	>=1570	High strength and high shock resistance when use. Used for stones, blocks and in mining layers f = 8.
TYG8C	14.5-14.9	>=88	>=1720	Good toughness and high strength. It is capable of resisting to high impact loads. Used for very hard stone and in mining layers f = 14.
TYG11C	14.0-14.4	>=86.5	>=2060	Good thermal strength, high resistance for wearing and impacting. Used in drilling on very hard walls and cements.
TYG15	13.9-14.2	>=86.5	>=2060	High hardness and toughness. Used for very hard mining layers.
TYG15C	13.8	>=86	>=2450	Optimum wearing resistance and high bending strength. Used for very hard mining layers.
