Questions
Is Brass C260 stronger than Wood?
Brass C260 is stronger: its yield strength is 345 MPa against tensile strength 99 MPa for Wood (3.48x).
Which is stiffer, Brass C260 or Wood?
Brass C260 is stiffer: Young's modulus 110 GPa against 12.5 GPa for Wood, so the same part in Brass C260 deflects less under the same load.
Which conducts heat better, Brass C260 or Wood?
Brass C260 conducts heat better: 121 W/m·K against 0.18 W/m·K for Wood.
Which expands less with temperature?
Wood expands less: 3.8 µm/m·K against 20 µm/m·K for Brass C260.
