NanoAl develops heat-treatable alloys for high-performance wire and cable

More and more new metal alloys are being developed every day to suit the needs of automakers, aerospace contractors, and other OEMs. They are stronger, harder, and can survive higher temperatures. The crystalline structures of the alloy are redesigned at the nanoscale and microscale to add these qualities. Two different companies, NanoSteel and NanoAl are developing different types of new steel and aluminum alloys using this technique.

NanoSteel's proprietary nanostructured steel alloy materials include sheet metal, powder metals, and surface coatings. It serves applications in extreme industrial environments, and in the oil & gas, mining, and power industries, as well as automotive.


Aluminium has been slowly substituting copper as a material of choice for wiring over the last two decades primarily because it offers twice the conductivity per weight at almost half the cost. According to NanoAl's CEO, CTO, and co-founder Nhon Vo, Aluminium needs to improve its fatigue strength, performance, strength/conductivity ratio, and temperature limitation to be at per with copper. As a result, NanoAl has developed a family of aluminium super alloys that can do away with the shortcomings of conventional aluminium alloys.

NanoAl is developing castable, heat-treatable alloys for high-performance wire and cable in collaboration with General Cable Corp. These alloys have up to three times the fatigue performance, 10,000 times better creep resistance, and twice the use temperature (425C) compared to traditional aluminium wires. These NanoAl's T Series aluminium alloys are redesigned at the nanoscale and microscale with reinforcements and precipitates.

These alloys offer exceptional mechanical and thermal stability notwithstanding the classic characteristics of pure aluminium like low cost, easy processing, light weight, excellent thermal/electrical conductivity, and high corrosion resistance. The same alloys can be used for wire, cable, and foil applications. They are flexible enough for batch processing, continuous casting, hot or cold casting other than being heat-treatable and weldable.
