Tantalum ni a danmeremere, fadaka awọ irin eyi ti o jẹ eru, ipon, malleable ati ductile nigbati funfun. O wa ni awọn iwọn kekere ni awọn ohun alumọni (ni gbogbogbo ni apapo pẹlu niobium), ati pe o ya sọtọ nipasẹ iyipada si oxide ati lẹhinna fluoro-complex, K2TaF7, lati inu eyiti a ti gba irin mimọ nipasẹ electrolysis.
Tantalum jẹ sooro ipata pupọ nitori iṣelọpọ fiimu ohun elo afẹfẹ, ati pe o tun sooro si ikọlu acid (ayafi ti HF).
