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

DWA-USA Al MMCs are being recognized as a material of choice for a wide range of demanding structural applications.  Although Aerospace represents our current, core market sector, the benefits of our products are being realized in an ever-expanding Al MMC marketplace. Some of the markets we serve are:

  • Aerospace
  • Space & Defense
  • Industrial
  • Automotive
  • High Strength- and Stiffness-to-Weight
  • Fatigue Resistance 2x that of conventional Aluminum
  • Tailorable, Low Coefficient-of-Thermal-Expansion
  • Isotropic Mechanical Properties


Al MMCs provide the commercial and defense aerospace communities material characteristics that translate into lighter weight designs, improved dynamic response, and maximum service life.  DWA-USA Al MMCs have replaced aluminum, titanium, steel and carbon fiber composites in a variety of applications.

  • Skins and Control Surfaces
  • Critical Rotating Parts
  • Struts and Longerons
  • Gearbox Bearing Liners
  • Hydraulics
  • Equipment Racking and sub-structure

Space & Defense

Space & Defense

The high stiffness-to-weight and tailorable, low CTE of Al MMCs has translated into improved part designs for space and defense applications.  Corrosion resistance is driven by matrix alloy selection and Al MMCs are always non-out gassing, making them ideal for high stability applications.

  • Stable Members
  • Optical Assemblies
  • Mechanical Systems
  • Trusses and End-fittings
  • Structural Longerons
  • Electronic Packaging

Al MMCs have been proven to reduce the weight of moving engine parts due to their high strength-and stiffness-to-weight, elevated temperature properties, and low CTE.  They also are an emerging material for bonded structural components possessing reduced weight and improved energy absorption for crash safety.

  • Pistons
  • Piston Pins
  • Connecting Rods
  • Suspension Arms
  • Frame Components
  • Engine Block Inserts

Industrial applications are an emerging market for DWA-USA Al MMCs.  More complex and sophisticated industrial manufacturing demands a broader selection of materials that provide high stiffness-to-weight, hardness and wear resistance, and lower CTE than that offered by conventional aluminum alloys.

  • Robotics
  • Gearing & Screw Drives
  • Braking Systems
  • Molds and Dies
  • Wind Turbines
  • Oil & Gas Extraction

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.
