Tungsten Cubes & Fragments
Tungsten Parts Wyoming manufactures high-density tungsten cubes and fragments in pure and heavy-alloy grades, machined powder-to-part in Laramie, Wyoming. At up to 19.3 g/cc, tungsten concentrates maximum mass into a compact cube for ballast, defense fragment programs, and collector applications.
Why Tungsten Cubes from TPW?
Tungsten concentrates maximum mass into a compact cube - the material of choice for ballast, defense fragment programs, and precision weighting:
- Maximum Mass in Minimum Size: At up to 19.3 g/cc, tungsten packs more weight into a compact cube than any practical alternative.
- Pure & Heavy-Alloy Grades: Available in pure tungsten and WNiFe/WNiCu heavy-alloy grades to match density and machinability needs.
- Precision-Machined Faces & Tolerances: Cubes and fragments machined to your dimensional and surface-finish specifications.
- US-Manufactured & Documented: Certificate of Conformance and full lot traceability on every order from Laramie, Wyoming.

Tungsten Cubes for Sale
Tungsten cubes are available in standard sizes from 1 inch up, plus larger and custom dimensions. The same density that makes a tungsten cube a popular desk object and collector piece, a 1.5-inch cube weighs about 2.2 pounds, makes alloy cubes and fragments critical components in defense programs. We supply both pure tungsten collector cubes and defense-grade alloy cubes and fragments; request a quote for sizes and pricing.
Frequently Asked Questions
Why is a tungsten cube so heavy?
Tungsten's density is 19.25 g/cc - about 1.7x lead and 2.5x steel - so a cube small enough to hold in one hand can weigh over two pounds.
How much does a 1kg tungsten cube cost?
Pricing depends on material grade, finish, and quantity - request a quote for current pricing.
What are tungsten cubes used for?
Beyond collector and desk objects: defense fragments, kinetic-energy components, counterweight elements, and density-reference standards.
See our Tungsten Properties Guide for density details. DFARS 252.225-7052 Sourcing Confirmation available per program.

Standard Rectangle and Hexagon Sizes
The standard tungsten rectangle measures 7.5 mm x 2.5 mm x 2.5 mm. The standard tungsten hexagon measures 4 mm across flats with a 4 mm height. Both carry the same ±0.15 mm tolerance as the cubes, and custom dimensions are machined to your drawing.
Lead Times
In-stock standard sizes ship in 3 to 5 days. Out-of-stock and custom runs take 10 to 12 weeks. Both vary with shape, size, and quantity, so confirm timing when you request a quote.
