The golden sections of Iron Man consisted of S.K.I.N (Synth-Kinetic Interface Nano-fluid), a liquid alloy that can be manipulated to conform to any desired shape. It is lightweight but has immense structural integrity, being harder than titanium and approaching low-grade adamantium. S.K.I.N. can be contracted to fit into a small container or stretched/shaped into another form. The alloy's wondrous properties were developed by Askew Technologies, and the exact elements incorporated into the S.K.I.N. remain unknown. Stark had set up the S.K.I.N. of his armor to be stored in a small container. On his command, the S.K.I.N. spilled out and assumed its default armor configuration.
