	Material	E GPa	ρ g/cm³	UTS MPa	UTS/ρ	E/ρ	CTE

Tick up to 4 to compare. UTS/ρ = specific strength and E/ρ = specific stiffness — higher means lighter for the same strength or rigidity.

Typical values — verify against your material spec and temper. A helper, not a substitute for engineering judgment.
