Watts,

Using the information you provided:

The density of aluminum is 2.8 grams per cm3

The density of liquidmetal is 6.1 grams per cm3

If 28 grams (1 oz.) was necessary to make the iPhone cover, and there are 2.8 grams per cm3 of aluminum, this would translate to 10 cm3 of aluminum in the cover.

10 cm3 of Liquidmetal would weigh 61 grams. With that being said, and knowing that Apple would frown on doubling the weight of anything within their product, it would be necessary to use half as much Liquidmetal as aluminum to not add significant weight to the product.

I am currently searching for the exact grade of aluminum used by Apple. I have only found references to "aircraft grade aluminum" which would lead me to believe they are using 6061. If I can determine the specific grade and temper of aluminum used by Apple, I may be able to determine the ratio of Liquidmetal to aluminum.

Disclaimer: I am no physicist, but I do have significant knowledge in metallurgy, welding, non-destructive, and destructive testing of various alloys.
