Copper Development Association alloy number.

W = Totally exposed in seawater on sides of structure, S = Exposed in base of structure so that ;
portion of each specimen was exposed in the bottom sediments.

Symbols for types of corrosion:
C = Crevice

CO = Coppering, a selective attack where copper

appears on surface similar to dezincification
CR = Cratering

DA = Dealuminification

ET = Etching

EWO = Etched only in the water

G = General

GBSL = General below sediment line

Numbers indicate maximum depth in mils.
Numbers refer to references at end of report.
Cast alloy.
