CLASS 1 Polishing Procedures
5.11.1 Aluminum and Aluminum Alloys
Aluminum and aluminum alloys are difficult to prepare because
they are soft and contain oxide particles which can become
dislodged and scratch the surface. The key to polishing aluminum
is to use very fine polishing abrasives (fine aggregates).
