Aluminium
Apple uses 7000 series aluminium for Apple Watch. That's the same used in lightweight
competition bikes. But to make it even stronger and durable, Apple altered it to create a
brand new alloy that's just as light, but 60 percent stronger, and one third the density of
stainless steel. To create the textured finish that reduces reflections, each case is machined
and polished before being blasted with microscopic zirconia beads. A special anodising
process then creates a hard, clear outer layer to protect against scratches and corrosion.
