Tungsten Carbide Density and Weight Calculator
Estimate tungsten carbide part weight from shape, dimensions and grade density. Choose your units, enter measurements, then select Calculate Weight. Results are for planning and quoting.
Tungsten carbide density and weight per cubic inch
These are the calculator’s illustrative planning presets. Actual cemented carbide density varies by grade and may fall outside these values. Use your selected grade’s published or specified density for final estimates; compare the Extramet grade chart when choosing material.
| Planning density | Pounds per cubic inch | Ounces per cubic inch |
|---|---|---|
| 14.5 g/cm³ | 0.524 lb/in³ | 8.38 oz/in³ |
| 15.0 g/cm³ | 0.542 lb/in³ | 8.67 oz/in³ |
| 15.5 g/cm³ | 0.560 lb/in³ | 8.96 oz/in³ |
At 14.5 g/cm³, a 1.000 in³ blank weighs about 0.524 lb, or 8.38 oz. Multiply volume by density to estimate other part weights, using consistent units.
Carbide rod, blank, and punch weight examples
Use the calculator for rods, rectangular blanks, discs, carbide punches, pins, and other carbide products. Diameter matters heavily on round parts because cylinder volume uses radius squared. For rectangular blanks, use the oversize stock dimensions when you are planning material yield and the finished dimensions when you need delivered part weight.
Volume = pi x radius squared x length. Weight = volume x grade density.
Volume = length x width x thickness. Add grinding stock before estimating material cost.
Use the quote checklist below to gather the required part details.
Example weights at 14.5 g/cm³
| Part geometry | Approx. volume | Approx. weight | Next step |
|---|---|---|---|
| 0.500 in diameter x 6.000 in rod | 1.178 in³ | 0.62 lb | Review blanks |
| 1.000 in diameter x 6.000 in rod | 4.712 in³ | 2.47 lb | Plan grinding |
| 2.000 x 1.000 x 0.500 in blank | 1.000 in³ | 0.52 lb | Send RFQ details |
For grade selection, compare Extramet grade options. For rotary-tool work, compare the request with cutting tool blanks. For finished part requirements, route dimensions through machining and grinding review, then send the drawing through the RFQ form.
How to estimate carbide part weight
Choose the closest shape and enter the dimensions of the part or blank being supplied. Include stock allowance for an unfinished blank, then select a planning preset or enter the grade’s specified density.
Use the result to estimate material, shipping and handling requirements or part mass during preliminary design. For a material comparison, review tungsten carbide vs steel.
Frequently Asked Questions
How heavy is pure tungsten per cubic inch?
How much heavier is carbide than steel?
Does the grade affect the weight?
Why is calculating weight important for quoting?
What is the formula for calculating weight?
(π × r² × Length) × Density.
The calculator converts metric and imperial inputs automatically. Results remain estimates based on the dimensions and density you enter.

Keep the tungsten carbide density and weight RFQ reference or one-page PDF summary handy for density conversions, diameter examples and planning notes.
What to include in your quote request
Send the calculator estimate with these details so Extramet can review the material and manufacturing requirements:
- Drawing, finished dimensions, and edge or radius notes.
- Material grade and the density source used for the estimate.
- Supplied blank dimensions and any oversize stock or grind allowance.
- Tolerances, finish and inspection requirements.
- Quantity and required delivery date.
