What metal is acid resistant?

Answer 1

Depends on what metal and what acid. Most common metals can be attacked by some type of acid. Other more rare and exotic metal are more resistant. Gold Platinum are resistant to almost all acids except for a mixture of Nitric and Hydrochloric acid (aqua regia) and in the case of platinum the mixture must be hot. Tungsten and Tantalum are also in this category. The only metal that is completely resistant to all acids at any temperature is Iridium, a platinum group metal. So the answer would be Iridium.

Answer 2

Some commonly used acid-resistant metals include stainless steel, nickel alloys, and titanium. These metals have a high level of corrosion resistance and are often used in environments where exposure to acids is a concern.
