A competator has introduced an aluminum burial vault that will be exposed to Formic Acid. Formic acid exposure will take place as a gas and later as a liquid. Formic acid is a product of decomposition of the human body. I have been asked to provide relative information for comparison to steel. I've read some "old" information on aluminum corrosion tests in soil. There is mention of PH, drainage, & soil conductivity. I need more information to complete the picture. Please help.
