Al / SiC Metal Matrix Composite (MMC)
O'Fallon Casting
O’Fallon Casting is the preeminent manufacturer of Investment Cast Al/SiC Metal Matrix Composite (MMC) castings in the world today. Its family of cast MMC’s contains particles of Silicon Carbide, ranging in size of 9 to 38 microns, homogeneously suspended in an aluminum matrix. The particle density can be varied, from 20%-40% Silicon Carbide by volume to create different properties of MMC.
Although MMC’s are difficult to machine, Investment Casting produces them in Near Net Shapes that helps to minimize the machining content.
Al/SiC MMC’s have Coefficients of Thermal Expansion and Specific Stiffness similar to cast Beryllium Aluminum but without the potential health hazard.

Aluminum Investment Castings
O'Fallon Casting
The casting of Aluminum Alloys comprises the largest part of O’Fallon Casting’s business. Most common are aluminum-silicon alloys 356 / A356 / 354 / C355 / A357 / F357. These alloys have excellent castability, weldability, pressure tightness and corrosion resistance. They are heat treatable and can be provided in various combinations of physical properties
The most frequently cast aluminum alloys are 356 and its higher purity version, A356. These are good general purpose alloys and because they are in wide use are advantageous in terms of cost and delivery.
