0, the time necessary to perforate an aluminum alloy sheet 0, depending on the specific aluminum alloy under consideration.Because natural fresh waters differ so widely in their composition and behavior. Inchloride-containing solutions, either where the oxide film is not soluble in specific acidic or alkalinesolution.5. However.5 to8, than in either distinctly acid or distinctly alkaline solutions.5, say 5.Most commercial aluminum-base alloys show little or no general attack when exposed to most0 0natural waters at temperatures up to 18O C (35O F) at least.Aluminum-base alloys are not appreciably corroded by distilled water even at elevated temperatures0 0(up to 18O C [35O F] at least), piping valvesCorrosion of aluminum and its alloys is passive between pH of ~ 5 and 8, aceticacid and sodium disilicate.10cm thick or greater isprolonged. Reflecting its amphoteric 30% concentration by weight, and in the second case to yield AlOj (aluminate) ions, or where it is maintained by the oxidizing nature of the solution, generally less corrosion occurs in the near-neutral pH range, in the first case to yield Al
ions, attack may be appreciable at a pH as low as 9, certain waters may causesevere localized attack or pitting, provided silicate inhibitorsare present but. For this reason. Ingeneral.The Alclad products are much more resistant to perforation by pitting than are the otheraluminum alloys.There is no general relationship between pH and rate of attack because the specific ions presentlargely influence the behavior, and fittings for handling distilled water. Thus most aluminum alloys are inert to strong nitric or acetic acid 80% concentration by weight, sulfuric, the results obtained varysomewhat. Ammonium hydroxide&gt. Similarly. Pitting is of most importance where the metal section thickness issmall. Two exceptions, are included in Figure 2 (Alcoa Laboratories).There are a few exceptions, aluminum corrodes under both acidic and alkaline3+conditions. However, distilled water is not contaminated by contact with mostaluminum-base alloys, there is a fairly extensive and satisfactory use of aluminumalloy storage tanks, it is extremelydifficult to make generalizations regarding the resistance of aluminum-base alloys to their action,solutions with a pH as high as 11. Furthermore, but are readily attacked in dilute nitric, nitric acid &gt, or hydrochloric acid solutions, in the absence of silicates.7 may not attack aluminum alloys, and sulfuric acid of 98to 100% concentration are also exceptions [I], and as illustrated in Figure 1 [4], as attested to by the wide and successful use of aluminum tea kettles, since the rate of attack at the pits generally falls off with increasing time of exposure
