AEROSPACE COMPOSITE
EARNS SAE-AMS
SPECIFICATION
The Society of Automotive En-
gineers—Aerospace Material Specifi-
cation Nonferrous Alloys Committee
(SAE-AMS) published aerospace speci-
fication AMS4355 for SupremEX 225XE,
a particle-reinforced, aerospace-grade
aluminum metal matrix composite
produced by Materion Corp., Mayfield
Heights, Ohio. SupremEX 225XE is made
by reinforcing a high-quality aerospace
aluminum alloy with 25 vol% ultrafine
silicon carbide particles, resulting in a
lightweight, strong, and stiff composite
that can replace aluminum, titanium,
steel, and other structural alloys and
composites. The AMS4355 specifica-
tion covers the material in reinforced,
hot isostatically pressed shaped billets.
Materion is working to obtain specifi-
cations for forged and extruded forms,
and other grades of the SupremEX
product line.
