Metal Matrix Composites – What is it?
Definition: A metal matrix composite (MMC) is composite material with at least two constituent parts, one being a metal. The other component may be a ceramic or an organic compound.
Metal Matrix: Aluminum
Ceramic Reinforcement: Alumina (Al2O3)
Typical Matrices: Aluminum, Magnesium, Cobalt
Most common reinforcement: Silicon Carbide, Alumina, Boron Carbide

Our proposition: a one-stop shop for MMC based comp onents
- Sister company of Del West founded in 2008
- Products :
- a new class of ceramic reinforced aluminum metal matrix composites
(AlMMC) by using a new reinforcement that consists of proprietary1)
micron size spheres of Al2O3
- Matrix: wide range of aluminum series (2000, 6000, 7000 series)
- Reinforcement: from 5% to 25% of alumina particles
- vertically integrated for the production of Al MMC ingots
- Differentiation:
- powder metallurgical processing permits the creation of matrix alloy compositions that can’t be obtained by conventional melting practice
- employment of ceramic spheres in the composite allows this class of materials to be machined with conventional shop carbide tools
Note: 1) patent pending
- Offer for MMC products:
- A single entry point for customers
- Product design & testing
- Component machining & coating using gamma technology MMCs
