Quotes from a Terry C Lowe's recent publication
.. "Most recently, coil-to-coil C-ECAP has been demonstrated for low-melting temperature alloys, including aluminum and magnesium.20 Coiling has been applied to produce AA6101 and AA6201 conductor alloys up to 12 mm in diameter. High-speed operation of C-ECAP has been piloted and these results have been used to estimate annual production volumes within a large-scale manufacturing environment, including consideration of alloy yield efficiency, tooling changes, coil handling, and machine maintenance. For C-ECAP of 9.5 mm diameter rod at 0.6 m/s with 96% production yield efficiency, a single C-ECAP system can produce 49.7 km of coiled aluminum conductor alloy per day, corresponding to 9.5 metric tons/day. Thus, for automotive conductor applications, a single C-ECAP system can produce an estimated 13,700 km/day of 130-µm diameter, 19-strand conductors. For high voltage overhead power lines, a single C-ECAP machine can produce 105 km/day of aluminum conductor steel-reinforced (ACSR) sparrow cable (six aluminum strands, each 2.67 mm in diameter) or 12.5 km/day of Osprey cable (18 aluminum strands, each 4.447 mm in diameter)"

"Competition between conventional and nanostructured metals
The most significant barrier to any new innovative product is the presence of the existing, and often long-established, conventional competing product. The improvements in metals and alloys are typically incremental, for example, 5% to 10% improvements over an existing product. But for nanostructured metals and alloys, the improvements in properties can be 30% to 200% beyond"
