E – elastic modulus σy – yield strength K1c – fracture toughness Ρ - density

Tmax – limiting temperature for engineering applications Cp – heat capacity λ – conductivity Diffusivity  λ/Cp

εD – dielectric constant ‘Hard’ magnet – permanently magnetized ‘Soft’ magnet – can be magnetized and demagnetized

Intrinsic resistance of a material in a given environment Rated on a scale of 1 (very bad) – 5 (very good)

Properties that determine the suitability of a material based on design requirements For the plane, strength, stiffness, and toughness are design limiting – if any of the three are too low, the plane will not fly
