DWA-USA, the global leader for Aluminum
Metal-Matrix-Composites for Lighter Weight Designs

DWA-USA produces cylindrical Aluminum MMC billets with diameters from 100 to 508 mm (4 to 20 inches) and weights from 2 to over 400 kg (2 to over 880 lb). For many applications, Al MMCs can be used in the billet form.

  • 2000, 6000, and 7000 series aluminum matrix alloys
  • SiC ceramic particle loadings from 5-50 Vol%
  • Uniform dispersion of fine ceramic particles throughout the aluminum matrix
  • Isotropic mechanical and physical properties

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.
