Tungsten alloy brick is used as ballast sailboats to provide momentum to resist the lateral forces on the sail. When sailing vessels carried cargo, it was at times necessary to sail to a port with no cargo.Insufficiently ballasted boats will tend to tip, or heel, excessively in high winds. To keep the boat safety, ballast is badly necessary, tungsten alloy brick is the best material to make sailboats counterweight because of the good properties such as high density, small volume, good corrosion resistance, non-magnetic if necessary.
