Near-Net Shape, Closed-Die Forgings with SiC Particle Loadings Up To 40 Vol%

Al MMCs are excellent forging alloys. They can be readily hand forged, and open and closed-die forged.   With fatigue resistance 2X that of conventional aluminum, opportunities for weight reduction and service life extension are substantial.

Significantly Lower “Fly-to-Buy” Compared to Aluminum and Titanium

The fine grain size of Al MMCs is maintained through the forging process.  A higher level of near-net shape forming is possible, compared to conventional aluminum and titanium.  The result is significantly reduced scrap and finish machining.  The “fly-to-buy” ratio of Al MMCs forgings can be less than 2:1.

Density Adjusted Properties of Aluminum MMCs Compared to Steel, Titanium and Aluminum

One of the clear advantages of Al MMCs compared to conventional metallic materials is greatly enhanced strength and stiffness. These property gains are achieved without impacting material density, so the specific properties of Al MMC are dramatically increased. Al MMCs are also isotropic composite materials. Their design space is not dependent on reinforcement orientation.

Aluminum Metal-Matrix-Composites Manufacturing

The Al MMC manufacturing process can be divided into three elements- primary processing, secondary processing and finishing. Unlike other composite materials, after primary processing of the billet, Al MMCs offer a high level of “fit, form and function” when inserted into the industrial manufacturing stream, making use of conventional facilities and equipment.
