| 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. |

| Like 2011, this
is also a general-purpose alloy for automatic screw machine work. It is stronger than 2011, but harder to machine and does not have the fine chip
associated with 2011. It is recommended for heavy-duty parts
because of its high strength. Workability is fair, with ductility and formability
considered better that 2014. Arc and resistance weldability
are satisfactory. Corrosion resistance is
fair. It is used for rivets, fasteners and aircraft components. |
