Monel K500 density is an important physical property used in engineering design, weight calculation, material selection, and cost estimation for components such as round bars, shafts, fasteners, and marine equipment. As a nickel-copper age-hardenable alloy, Monel K500 maintains a relatively high density compared to steel and aluminum alloys, which directly affects its performance in structural and rotating applications.
Monel K500 Density Overview
The density of Monel K500 is typically around 8.44 g/cm³ (0.305 lb/in³). This value is very close to Monel 400 due to their similar nickel-copper base composition. The slight difference comes from the addition of aluminum and titanium used for age hardening.
| Property | Monel K500 Value |
|---|---|
| Density | ~8.44 g/cm³ |
| Density (lb/in³) | ~0.305 |
| Base System | Nickel-Copper Alloy |
