What formula is used to calculate nickel round tube weight?

Weight = (π ÷ 4) × (OD² − ID²) × Length × Density. OD is the outer diameter, ID is the inner diameter (OD − 2 × wall thickness), Length is the tube length, and Density is the alloy density in kg/m³. All dimensions must be in the same unit (meters internally) before multiplying by density.

What is the standard density of pure nickel?

Pure nickel (Nickel 200 and Nickel 201) has a density of 8908 kg/m³ (8.908 g/cm³ or 0.3219 lb/in³). This is the value specified in ASTM B161 and most engineering handbooks for nickel round tubing.

How is inner diameter derived from wall thickness?

Inner Diameter (ID) = Outer Diameter (OD) − 2 × Wall Thickness. The calculator validates that wall thickness is less than OD/2 so that the resulting ID is always positive.

Which nickel alloys are supported?

Nickel 200/201 (8908 kg/m³), Monel 400 (8800 kg/m³), Inconel 625 (8440 kg/m³), Inconel 718 (8220 kg/m³), Hastelloy C276 (8890 kg/m³), and Incoloy 825 (8140 kg/m³). A custom density field is also available for unlisted alloys.

What units can I use for the dimensions?

Outer diameter and wall thickness accept mm, inches (in), or centimeters (cm). Length accepts meters (m), millimeters (mm), feet (ft), or inches (in). All values are converted to meters internally before the calculation.

Can I calculate weight for a batch of multiple tubes?

Yes. Set the Quantity field to the number of tubes. The result card shows both the single-tube weight and the total batch weight.
