The MacBook Air will now be assembled with a shell made from a custom alloy created by the company’s material team. “Apple’s metallurgy team has designed an aluminium alloy that uses excess aluminium from the production process,” said Grove.
“It’s designed to use fine shavings of recaptured aluminium that are re-engineered down to the atomic level. This new alloy is as beautiful and robust as any we’ve used before,” continued Laura Metz, Apple’s senior product manager.
The alloy makes construction of the computer possible “without mining any new aluminium from the earth,” according to Apple. The use of 100 per cent recycled aluminium in the casing has been verified by UL, a global safety consulting and certification company based in Illinois.
The recycled aluminium can itself be recycled. “This helps reduce the carbon footprint of the new Air by nearly 50 per cent and makes it the greenest Mac ever,” continued Metz.
