MMC Data

MMC Data

DWA Technologies has developed a wide range of Micro & Nano MMCs to meet the specific requirements of a very wide range of markets and applications by using its proprietary micro, 2-phase nano and 3-phase nano material and processing technologies. The following is general information and typical mechanical property data for the Company's four MMC material systems:

Micro-2 & Nano-2 MMCs
Micro-6 & Nano-6 MMCs
Micro-7 & Nano-7 MMCs
BORTEC^® MMC Neutron Absorbing Material

Please note that the mechanical properties of each class of Micro & Nano MMCs can be adjusted to fit the specific requirements of the end-product manufacturer. Please contact us for additional information and property data.

Micro-2 & Nano-2 MMCs

Micro & Nano-2 MMC systems have been developed particularly for high temperature applications. They have higher strength at elevated temperatures, lower Coefficients of Thermal Expansion ("CTE"), higher fatigue resistance and higher wear resistance than those of conventional high temperature aluminum alloys. Fatigue resistance is a particularly differentiating property providing improvement of two orders of magnitude in high cycle fatigue conditions comparing with 2000 series aluminum alloys. Micro-2 & Nano-2 MMCs can be extruded, forged, rolled, machined and heat treated in a manner similar to the base aluminum alloy. Figure 2 compares Nano-2S/MMC with 2618-Al and 4032-Al between room temperature and 200°C.

Micro-6 & Nano-6 MMCs

Micro-6 & Nano-6 MMCs were developed for replacement of 6061-Al with higher strength, higher modulus, higher fatigue life and good corrosion resistance. Micro-6 & Nano-6 MMCs can be extruded, forged, rolled, machined, heat treated and welded to itself or 6061-Al. Micro-6 & Nano-6 MMCs have better properties than 6061/Al₂O₃MMC. Table 1 compares tube extruded from 6061-Al, 6061/Al₂O₃/22p MMC and Nano-6/MMC.

Tube	Density (g/cm³)	Specific Modulus (vs. 6061-Al)	Yield Strength (ksi) [MPa]	Shear Strength (ksi) [MPa]	Elongation (%)
6061-Al	2.7	100%	40 [276]	27 [186]	12
6061/Al₂O₃MMC	2.95	130%	45 [310]	27 [186]	1
DWA Nano-6/MMC	2.68	136%	60 [413]	45 [310]	7

Micro-7 & Nano-7 MMCs

Micro-7 & Nano-7 MMCs are high strength lightweight aluminum MMCs. The yield strengths of Nano-7 MMCs are above 100 ksi (~700 Mpa), which is significant higher than 7075-Al. Nano-7 MMCs can be extruded, forged, rolled, machined and heat treated. Table 2 compares

7075-Al	2.8	75 [517]	10
DWA Nano-7/MMC	2.8	102 [703]	6

BORTEC^® MMC Neutron Absorbing Material

BORTEC^® MMCs are boron carbide reinforced aluminum MMCs specially developed as neutron absorbing material for nuclear shielding material. Technical data of BORTEC^®can be found in BORTEC^®.
