Table 2 - Copper Alloy vs. Corrosives Compatibility Chart

Alloy Categories Liquid Corrosives Moist Vapors
Notes:

E = excellent, immune for all practical purposes.

G = good, not immune, but corrosion rates acceptable.

F = fair, corrosion > than G, but can be used if corrosion can be tolerated, in intermittent service or coated.

P = poor, unsuitable due to excessive corrosion.

ND = No data
