1. Tantalum has good resistance to chemical corrosion, and its corrosion rate in the chemical environment is 0~0.05mm/ a. In sulfuric acid, nitric acid, hydrochloric acid, aqua roya, perchloric acid, chloride, bromide, ammonia-ausic acid, phosphoric acid, chlorine oxides, hypochlorous acid, organic acid (including chloroacetic acid), hydrogen peroxide and all salts that do not produce free hydrofluoric acid or strong base in the hydrolysis reaction and in hot and cold seawater, have very good corrosion resistance. 2. But it has good temperature resistance, its melting point is 2996"℃, and has good heat conductivity.
3. Excellent cold forging, easy to work at significantly below room temperature, recrystallization temperature between 900℃ and 1450℃.
4. It has good biological adaptability and good compatibility with human body fluids. It will not cause anaphylaxis during medical operation.
