Basics of metal polishing

Basics of Aluminum

Aluminum is a porous metal. the ease of polishing is nearly 100% related to this fact as we are actually cutting the top surface of the
pores off and smoothing the surface of what remains. Think of the pores like sharks teeth. When the aluminum comes in the pores
edges are rough and jagged and when it leaves they are smooth dimples reflecting more light and giving the shine we seek. Due to its
porosity aluminum absorbs fallout, pollution and other environmental factors, these can contribute to the loss of shine. Another
drawback to the material being porous is that without regularly getting polished aluminum has a tendency to dry out and whiten in
color. It is important to remind customers that with simple hand maintenance and a machine polish annually at worst their shiny
product will remain that way longer and will protect the Material from absorbing (toxins?) or drying out.

Aluminum Tools & Supplies
– Buffer/grinders (we prefer GA7021 6000 rpm)
– Flanges -> ideally if using more than a few times a month
– Buffs (cut/color)
orange (cut) & yellow (color) >>> aluminum
red (cut) & pink (color) >>> stainless
– Rouge brown/green (aluminum)  -or- black/yellow (stainless)
– Rake
– Tape
– Extension cords
– Sanders
– Paper various grits 220, 320, 400
– Advanced speed sand pad (soft)

Aluminum Maintenance Levels
– Washing
– Washing >>> hand polish >>> heavy cut
– Cut buffing followed by coloring
– Sanding cutting coloring
Levels of Aluminum Deterioration Descending
– Polished just dirty >>> wash and hand polish
– Dull/hazy polish >>> cut then color
– Pitted >>> heavy cut buff then hand polish or sand and polish
– Oxidized/acidized (discernible by white coloration enlarged pores dry appearance) >>> heavy sand cut n color
