Footnotes: (a)Brass: Some type of brass
have less corrosion resistance than is shown on the
chart, others have more, e.g. Aluminium brass. (b)Copper-nickel
alloys: Based on behaviour of Cu/Ni 90/10; 70/30 may
be generally more resistant. (c)Gunmetal: The data
refer only to high tin gunmetals. (2)Depending on
the acid. (4)Fair resistance. (11)Anhydrous (20)Not
aerated solutions (30)Depending on composition (36)Over
85%. (53)In absence of dissolved O2 and CO2 (60)May
discolour liquid/ product (62)Depending on type. (73)Not
ammonium. (82)Provided more than 70% copper. (83)Water
less than 150ppm. (119)Pure solution. (175)With
