Struct ThermalProps 

pub struct ThermalProps {
    pub conductivity: ThermalConductivity,
    pub specific_heat: SpecificHeat,
    pub expansion: ThermalExpansion,
    pub emissivity: f64,
}

What it does with heat.

The two fields worth checking against the real part

specific_heat and emissivity are where a wrong number does the most damage, and they are the two a user is most likely to carry over from something that looked close enough.

A composite assembly is not a billet of its main metal. A BLDC motor is copper, electrical steel, magnets and air; its bulk c_p is nearer 450 J/kg/K than aluminium’s 896. Reaching for Substance::aluminium_6061 because it is the metal in the catalogue doubles the thermal time constant and changes the conclusion, with nothing to warn you — the answer stays plausible, it is just for a different object. Use Substance::with_specific_heat on whichever entry is closest and put the real figure in.

Emissivity is a surface, not a substance. The same 6061 is 0.09 polished and about 0.9 anodised, a factor of ten in the radiative path — which Environment::loss_from says is the same order as still-air convection at room temperature. Substance::with_emissivity exists so a finish does not have to become a new material.

Fields

conductivity: ThermalConductivity

Fourier’s k: how fast heat moves through it.

specific_heat: SpecificHeat

c_p: how much heat it takes to warm it.

expansion: ThermalExpansion

Linear expansion per kelvin — the property that turns absorbed light into a focus shift.

emissivity: f64

Emissivity, 0..1, for radiative exchange. 1 is a blackbody; polished metal is near 0.05, which is why a shiny shield works.
