520.0 Sand Cast Aluminum Modulus of Rupture

[chief52]

I am working on a bending analysis for a part made from 520.0 sand cast aluminum (T4 temper). I am having a hard time finding mechaincal strength properties for this material that will be acceptable for airworthiness certification purposes. Same for modulus of rupture curves or charts for this material.

I have not had any luck with MMPDS-01, ANC-5 or Bruhn.

Any suggestions or thoughts on where I might find data for this material is appreciated.

Check MatWeb.com.

Although that site is not acceptable for certification purposes, its lists the following references for your material:

Metals Handbook, Vol.2 - Properties and Selection: Nonferrous Alloys and Special-Purpose Materials, ASM International 10th Ed. 1990.

Structural Alloys Handbook, 1996 edition, John M. (Tim) Holt, Technical Ed; C. Y. Ho, Ed., CINDAS/Purdue University, West Lafayette, IN, 1996.

Information provided by The Aluminum Association, Inc. from Standards for Aluminum Sand and Permanent Mold Castings (14th Edition, 2000) and/or Designations and Chemical Composition Limits for Aluminum Alloys in the Form of Castings and Ignot (revised 1999).

chief52... very important...

520.0-T4... but what type (sand, permament mold, metal die, etc) and what procurement spec (MIL, AMS, ASTM, etc)???????
