| 1 Ratings A through E are relative
ratings in decreasing order of merit, based on exposures to sodium chloride solution by
intermittent spraying or immersion. Alloys with A and B ratings can be used in industrial
and seacoast atmospheres without protection. Alloys with C, D and E ratings generally
should be protected at least on faying surfaces. |
| 2 Stress-corrosion cracking ratings
are based on service experience and laboratory tests of specimens exposed to the 3.5%
sodium chloride alternate immersion test. |
| A= |
No known instance of failure in service or in
laboratory tests. |
| B= |
No known instance of failure in service;
limited failures in laboratory tests of short transverse specimens. |
| C= |
Service failures with sustained tension
stress acting in short transverse direction relative to grain structure; limited failures
in laboratory tests of long transverse specimens. |
| D= |
Limited service failures with sustained
longitudinal or long transverse |
|
|
| 3 Ratings A through D for Workability
(cold), A through E for Machinability and A through C for Anodize Response, are relative
ratings in decreasing order of merit. |
| 4 Ratings A through D for Weldability
and Brazeability are relative ratings defined as follows: |
| A= |
Generally weldable by all commercial
procedures and methods. |
| B= |
Weldable with special techniques or for
specific applications that justify preliminary trails or testing to develop welding
procedure and weld performance. |
| C= |
Limited weldability because of crack
sensitivity or loss in resistance to corrosion and mechanical properties. |
| D= |
No commonly used welding methods have been
developed. |

| This alloy is used in aerospace applications
such as space booster and fuel tanks. The alloy is readily weldable. It is useful over a
temperature range of -452º to 600 ºF. The alloy also has good fracture toughness. The T8
temper is resistant to stress corrosion
craking. |
