Monel 500 Rod is a nickel-copper alloy rod strengthened by γ' phase. Its unique aging hardening characteristics are derived from the Ni₃(Al,Ti) ordered phase formed by aluminum, titanium and nickel matrix. The alloy has similar processing properties to Monel 400 in the solid solution state. When the aging temperature is controlled in the range of 480-620℃, the nano-scale precipitation phase can increase its Vickers hardness from 180HV to more than 300HV, while maintaining an elongation of about 25%, achieving an optimized match between strength and plasticity.

The strengthening mechanism of the alloy rod shows obvious temperature dependence: when it is in service below 300℃, the precipitation phase remains stable; when the temperature exceeds 650℃, the strengthening phase begins to coarsen, but still maintains a high-temperature strength better than Monel 400.

This characteristic makes it particularly suitable for manufacturing precision parts that must withstand both mechanical stress and stress corrosion resistance. Its microstructural stability can be precisely controlled by controlling aging process parameters (such as aging time, cooling rate, etc.).
