Tungsten Alloy Marine Counterweights: Benefits and Drawbacks Explained

Tungsten Alloy Marine Counterweights: Benefits and Drawbacks Explained

Tungsten‑alloy marine counterweights combine a high density of 18.6 g/cm³ with excellent machinability, tensile strength, and hardness. These attributes help vessels achieve superior stability while remaining environmentally friendly. In the following sections we compare tungsten alloy to iron, zinc, and lead counterweights, outlining their respective strengths and limitations.
