To reduce the production of slivers the severity of friction at the point where the two surfaces interface must be reduced.
The general rule for cutting materials is the softer the metal the smaller the cutting clearance.
With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet.
Improper clearance will reduce the die service life or burrs and lead to secondary cutting the irregular opening will increase the demounting force etc.
Aluminum is non magnetic and provides good thermal and electrical conductivity.
Tired of getting fingers cut on sheet metal while using tin snips.
An angle grinder fitted with an abrasive metal cutting disc works well to cut all kinds of metal including bolts angle iron rebar and even sheet metal.
If you re cutting a line in a sheet of aluminum you can skip the vice and cut your way down the sheet on a flat surface.
