Tungsten mud has many unique properties, mainly reflected in arbitrary shape, viscosity, non-toxic, hydrophobic and high density. The density of tungsten mud is generally in the range of 8G / cm3 ~ 10g / cm3, which is second only to that of lead (11.3g/cm3). In addition, the shape of tungsten mud can be changed at will, which makes it more flexible when used for counterweight adjustment.
Tungsten mud also has stickiness and water resistance, which is mainly manifested in the use of fishing gear. Tungsten mud can replace the drop products as a counterweight for fishing hook diving.
Common grades, compositions and properties of tungsten alloys:
| Class | 1 | 2 | 3 | 4 |
| 鎢比例% | 90 | 92.5 | 95 | 97 |
| 密度（g/cc） | 16.85-17.25 | 17.15-17.85 | 17.75-18.35 | 18.25-18.85 |
| 硬度（HRC）Max | 32 | 33 | 34 | 35 |
| 極限抗拉強度(ksi) | 110 | 110 | 105 | 100 |
| mpa | 758 | 758 | 724 | 689 |
| 屈服強度 at 0.2% off-set(ksi) | 75 | 75 | 75 | 75 |
| mpa | 517 | 517 | 517 | 517 |
| 延伸率% | 5 | 5 | 3 | 2 |
Tungsten alloy material has high density, high melting point, high hardness, high ultimate tensile strength, easy cutting, high elastic modulus, can effectively absorb X-ray and gamma ray (the absorption of X-ray and gamma ray is 30-40% higher than that of lead), non-toxic, pollution-free, corrosion resistance, good heat and conductivity characteristics. Therefore, it is widely used in the military field, such as the small arrow of cluster arrow, the "gunpowder cover" of shaped charge projectile, scattered ammunition, cluster ammunition, armor piercing projectile, etc., and has great lethality. In aerospace, missile and aviation industry, it is used for gyroscope components, missile guiding device, lift control and rudder balance device of aircraft and helicopter. In the field of sports goods, it is used for car crankshaft counterweight, golf head counterweight, tennis racket counterweight, dart pole, etc. Due to its high density and excellent radiation absorption ability, high specific gravity tungsten alloy is an excellent shielding material, which can be used as medical shielding tank, collimator, pet syringe, etc. With the increasing requirements of environmental protection, it has been widely used in the field of fish drop and gradually replaced the plumb.
