Extending Metal Performance with Reinforced Materials

Metal Matrix Composites (MMCs) are advanced composite materials that combine a metal matrix with various reinforcements to enhance strength, wear resistance, and high-temperature performance. InssTek’s DED technology enables the stable fabrication of various MMCs structures through precise process control.

Why Metal Matrix Composites?

Conventional metals alone cannot simultaneously meet all the performance requirements of diverse industrial environments. MMCs overcome the limitations of conventional metals by optimizing the combination of a metal matrix and reinforcements, delivering the performance required for a wide range of industrial applications.

Conventional Metal

• Lower Strength
• Poor wear resistance
• Limited high-temperature performance
• Higher weight

MMCs

MMCs (Metal Matrix Composites)

• Higher Strength
• Excellent wear resistance
• Superior high-temperature stability
• Lightweight

• 
  High Strength

  Reinforcement strengthens the metal matrix for superior strength.

• 
  Wear Resistance

  Ceramic particles provide excellent wear and abrasion resistance.

• 
  High-Temperature Stability

  Maintains mechanical properties extreme temperature conditions.

• 
  Lightweight

  Lower density with high performance enables weigth reduction.
