Tungum Alloy has a high level of general corrosion resistance, allowing it to be specified for use in systems containing, or operating in the presence of, a variety of substances / solutions.
The ratings below are the result of laboratory tests conducted under the controlled conditions noted.
They are published for guidance only. Where any doubt exists, samples of Tungum are freely available for field trials to replicate the precise operating conditions.
Rating: E
Excellent resistance – minimal attacks take place.
Rating: G
Good resistance under the conditions of test.
Note: Tungum Alloy should not be used in the presence of Acetylene, Ammonia or Mercury.
