| Machinability |
A combination of chip size, tool wear, cutting force, part
dimensional control and part surface finish. |
| Preferred Alloys |
2011, 6262,
6040, 6033 |
| Lead-Free |
The absence of intentionally added lead to an alloy, i.e. less than 0.05%
by weight. |
| Preferred Alloys |
|

| Corrosion
Resistance |
Preferred Alloys |
| 1- All of the 7XXX alloys in the T76 temper. |
| 2- All of the 7XXX alloys in the T73 or T74 tempers. |
|
| Wear
Resistance |
Resistance to galling and/or abrasive wear in parts subjected to sliding
friction. |
| Preferred Alloys |
4026 is an
aluminum-silicon alloy that has been developed for wear resistance. Other alloy families generally require hardcoat anodizing for wear
applications. |
| Light Weight |
Aluminum is 1/3 the weight of steel for an equivalent volume. |
| Anodize
Response |
The ability to accept hard coat, bright dip or color anodize coatings. |
| Preferred Alloys |
6033, 6061, 6262
, 6040; other alloy families can be anodized but
require tighter controls. |
