Product Code:SAE AMS4178
Title:Core, Flexible Honeycomb, Aluminum Alloy, Treated for Sandwich Construction, 5052, 350 (177)
Issuing Committee:Ams D Nonferrous Alloys Committee
Scope:This specification covers an aluminum alloy in the form of honeycomb core in a non-hexagonal, flexible cell configuration, the core being treated for increased corrosion resistance and furnished only in the expanded form. This honeycomb core has been used typically in contoured sandwich construction for short-term exposure up to 350 掳F (177 掳C) or for long-term exposure up to 200 掳F (93 掳C), but usage is not limited to such applications.
