If you notice these alloy elements add up to 100. This alloy can be thought of more as 92% Al with 2% each of the other elements. Its a metal-metal matrix composite, primarily pure aluminum with localized, tiny grains of what would be thought of as a traditional alloy (various aluminum-titanium, aluminum-iron, etc. alloys)
