What is the density of Ni 200 and Ni 201?

Both Ni 200 (UNS N02200) and Ni 201 (UNS N02201) have a nominal density of 8.89 g/cm³ (0.321 lb/in³). Ni 201 is the low-carbon variant preferred for applications above 315 °C but the density is identical for weight calculation purposes.

What cross-section shape does this calculator assume?

The calculator models a standard C-channel (also called a U-channel or parallel-flange channel) with uniform wall thickness t. The cross-sectional area is A = t × (2B + H − 2t), which accounts for the web and two flanges without double-counting the corners.

Can I use this for other nickel alloys like Monel or Inconel?

Not directly — the density presets are specific to Ni 200/201 (8.89 g/cm³). Monel 400 is approximately 8.83 g/cm³ and Inconel 625 is approximately 8.44 g/cm³. You can use the custom density field to enter any value for other alloys.

Why does the formula subtract 2t in the area calculation?

The two flange plates each span the full flange width B, and the web spans the height H. However, where the flanges meet the web at the corners, the material is already counted in the flange area, so we subtract 2t from the web height to avoid counting those corner zones twice.

What units does the calculator accept?

Cross-section dimensions (H, B, t) are entered in millimeters. Length can be entered in millimeters or meters — use the unit toggle to switch. Weight is reported in both kilograms and pounds.
