Armstrong throws a debris of EXCELSUS at Raiden as seen here.
Mass of the debris[]
We need to use pixel scaling on them to find their volume.


All pixel scaling here:

Since length is a bit ass to find, I scaled it from two images.
Armstrong's height is 200 cm
First image:
200 cm: 144 px
Height: 349 px= 2.423611111111111 m
Width is not full but was counted at 381 px, but since it's cut, we're gonna use 400 px
400 px = 2,777777777777778 (roughly 3 meters)
Now about it's length:
First distance
200 cm = 100 px
Distance from Armstrong = 744 px = 7.4 meters
Distance from Armstrong 2 = 718 px = 5.653543307086614 (due to it being cut again I'm gonna rought it up at ~6m)
Total length: 13.4 meters
V=2.423611111111111×13.4×3=97.596 m^3
m=97.596 m^3*1300 kg/m^3 (carbon nanotube density)
m=127,874.8 kg
Arm movement[]
This was pulverised as seen here, I don't know value for pulverization, but I'm going to use 500 GPa
97596000cm3 x 500000jcc (500Gpa) = 48798000000000j

I will assume he moves his arm in a 120 degree.
Armstrong is 2 meters tall, so his arm length should be 0.8 meters.
48798000000000j / 1.6755m = 29124440465532.6768128916741271N (Class T)

Lifting Strength:
2969866413.7 tons (Class T)
Might be kinda higher because the energy to pulverise it is considerably more than the fragmentation end I'm using.
