Kaiser Aluminum Alloy 4026 T651 Rod & Bar

Subcategory: Aluminum Alloy; Nonferrous Metal; 4000 Series Aluminum Alloy

Close Analogs: Aluminum content is determined by balance.

Material Notes:
This alloy is used when high strength with wear and/or galling resistance is required. It can eliminate hard-coat anodizing in some applications. Typical applications include air compressor pistons and automotive transmission valve parts. It has good machining characteristics, producing small chips and good surface finish.

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.
