Weight CalculationTo calculate the weight of an Inconel 718 part:

1. Determine the volume of the part in cubic inches or cubic centimeters.
2. Multiply the volume by the density:
   • For cubic inches: Weight (lbs) = Volume (in³) × 0.296
   • For cubic centimeters: Weight (g) = Volume (cm³) × 8.19

Key Considerations

• Inconel 718’s high density contributes to its excellent strength-to-weight ratio.
• The alloy’s weight stability at high temperatures makes it suitable for aerospace applications.
• Cold working can increase the alloy’s strength but may affect its weight distribution in complex parts.

Inconel 718’s combination of high strength, corrosion resistance, and relatively stable weight properties make it an ideal choice for applications in aerospace, oil and gas, and other industries requiring high-performance materials.
