No. Black tip has a core made of tool steel (steel hardened to BHN 600+), making it strong and hard but brittle.So is this the same bullet as the "Black" tip 30-06 military surplus ammo......???
Tungsten carbide is a ceramic of tungsten and carbon. It is more than twice as dense as steel (7.6 g/cc vs 15.6 g/cc) and harder, but also brittle.
Both will penetrate monolithic targets quite effectively, but their brittleness means they might have trouble with multi-layer targets. If an early layer causes the core to fracture, the shards will penetrate later layers to a shallower depth.
A milder steel (like the soft BHN 170 steel in most 7.62x39mm, or harder steels up to BHN 350 or so) will penetrate monolithic targets to less depth, but will better hold their shape (deforming rather than shattering) and may do a better job penetrating multi-layer targets.
DU and Tungsten-heavy alloy give you the best of both worlds. They are extremely dense (19.0 g/cc for DU, 17.0 g/cc for W90-Ni7-Fe3), hard and strong, but also have enough ductility to not shatter in multi-layer targets.
