Tungsten Alloy Counterweight for Sailboats

What Is Tungsten Alloy Ballast for Sailboats?


Ballast is used in sailboats to provide momentum to resist the lateral forces on the sail. Insufficiently ballasted boats will tend to tip, or heel, excessively in high winds. Too much heel may result in the boat capsizing. When sailing vessels carried cargo, it was at times necessary to sail to a port with no cargo. In order to do this enough ballast of little or no value would be loaded to keep the vessel upright. Tungsten alloy sailboat counterweight would then be discarded when the cargo was loaded.
(You can get more information from http://en.wikipedia.org/wiki/Sailing_ballast.)

On larger modern vessels, the keel is made of or filled with a high density material, such as lead. However, lead is not environmentally friendly and toxic. Because high density and its non-toxic, tungsten heavy alloy is increasingly adopted in counterweighs for sailboat. By placing the weight as low as possible (often in a large bulb at the bottom of the keel) the maximum righting moment can be extracted from the given mass. Traditional forms of ballast carried inside the hull were stones or sand.

Special properties for tungsten alloy weights
Here are some main advantages of tungsten alloy sailboat counterweights:
- High density- up to 18.5 g/cm3.
- Up to 65% denser than Lead.
- Up to 130% denser than Steel.
- Mechanical properties to suit either dynamic or static locations.
- Weakly Ferro magnetic.
- Non-magnetic, if specifically required.
- Safe and environmentally friendly alternative to Lead.
- Non-Toxic.
- Corrosion resistant.
- Easily machined.
- Easily mechanically joined, brazed or shrunk fit to other materials.
- Equivalents to most commercial specifications available.

Tungsten Alloy Sailboat Counterweights
