Corrosion Index


Corrosion properties of Carbon Steel, Brass, Cast Iron, Copper, Titanium, Aluminium, Bronze.

The table below indicates the approximate corrosion resistance of selected metals to a range of common chemicals. This is collated information from various sources but is of limited quality. For good quality information please consult reputable reference texts and/or the links provided below the table.

Key to Letters designating corrosion resistance
  • A...Excellent Minimum attack
  • B...Acceptable minor corrosion
  • C...Medium corrosion attack - Should not use
  • D...Severe attack -
  • "-" No information

Important note: The table relates to fluids at ambient temperatures (approx 21 oC )unless stated otherwise
