The first successful aluminum cranks were introduced in 1933 by Stronglight (photo at the top).They used a square taper fitting on the spindle instead of the cotters used by most steel cranks at the time.Graphite was available in the "lesser" component groups, and was a darker, opaque grey/black.

When Campagnolo offered his first cranks in 1958 (above, 1965 version shown), Campagnolo used five arms for the spider instead of Herse’s three arms.They drilled holes into the crank’s spider, tapped them, and attached the third ring with spacers.The photo above shows one of these home-made conversions.As their name implied, these cranks were strong and light. The chainring attached to a small flange on the right crankarm, as was common among cranks at the time.
