2.2mm 1.2mm 1.1mm 2.8mm Miniature Solid Aluminum Bearing Balls Aluminum Beads
Aluminium balls are characterized by good corrosion resistance and hard-wearing properties,
and also come with smooth surface finishes.
The basic class (1xxx) simply has good wear and corrosion resistance, and come with a minimum aluminium content of 99%.
However, they are also aluminium alloys, so traces of iron, magnesium, silicon, and copper will be present.
