A 1-inch cube of tungsten weighs approximately 0.68 pounds (308 grams)

A 1-inch cube of tungsten has a volume of 1 cubic inch and a mass of about 0.68 pounds or 308 grams. This high density makes tungsten one of the heaviest common metals, with a specific gravity of 19.25 g/cm³. The weight is equivalent to holding a standard baseball or slightly more than two AA batteries.

Factors affecting tungsten cube weight

• Purity: Commercial tungsten is typically 95-99.5% pure, with impurities slightly reducing density
• Temperature: Density decreases by about 0.005% per degree Celsius above room temperature
• Manufacturing: Sintered tungsten may have microscopic voids, reducing weight by 0.1-0.5%

Practical applications of tungsten's weight

• Counterweights: Used in aircraft and racing vehicles for precise balance
• Radiation shielding: High density provides effective gamma/X-ray protection in compact form
• Aerospace components: Counterbalances in satellites and precision instruments
• Jewelry: Premium density provides substantial feel in wedding bands and accessories
