ToughMet® 3CX CX105 – Advanced Spinodal Hardened Copper Alloy
ToughMet 3 Alloy is Materion Performance Alloys’ solution to your severe service material problems. By applying our proprietary technology process to create the EquaCast® microstructure, tailored alloying additions and spinodal hardening technology, we have engineered ToughMet 3 Alloy to provide attributes beyond those typically found in a high-strength copper alloy. ToughMet 3 Alloy in the cast and spinodally hardened (CX) condition exhibits tensile strength up to 120 ksi and hardness up to HRC 34 in a Copper - 15% Nickel - 8% Tin alloy with excellent machinability.
