Copper C110 and the Isola 370HR laminate from this library; the layers conduct in parallel along the board and in series through it (boardStackup.ts). Its two 0.0028 in trace layers cover little of the board and are left out; vias are ignored. Mechanical values are the bare laminate's.
Every value links to the document that states it. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
Questions Is Brass C360 stronger than PCB Board FR-4, 2 copper planes? PCB Board FR-4, 2 copper planes is stronger: its tensile strength is 315 MPa against yield strength 310 MPa for Brass C360 (2%).
Which is stiffer, Brass C360 or PCB Board FR-4, 2 copper planes? Brass C360 is stiffer: Young's modulus 96.5 GPa against 23.9 GPa for PCB Board FR-4, 2 copper planes, so the same part in Brass C360 deflects less under the same load.
Which expands less with temperature? PCB Board FR-4, 2 copper planes expands less: 13.5 µm/m·K against 20.5 µm/m·K for Brass C360.
