* High density
The reason why it is called high-gravity tungsten alloy is because of its high density. The tungsten content in high-gravity tungsten alloys is between 90% and 98%. The density of tungsten alloy is 16.5~18.6g/cc. High density tungsten alloy can be made into shielding parts. Compared with the shielding of the same weight, the radiation absorption capacity of the high-gravity tungsten alloy shielding is comparable to that of it, and the volume is only 1/3.
* High melting point
Tungsten has the highest melting point of all metals (3422°C, 6192 °F), the lowest vapor pressure (temperatures above 1650 °C, 3000 °F will liquefy), and the highest tensile strength.
* Small size
High specific weight tungsten alloy counterweight
Compared with the fishing pendant made of other materials, the size of the fishing pendant made of high gravity tungsten alloy is smaller. Therefore, there is no need to hang too much tungsten alloy fishing pendant on the fishing line.
* High hardness
* High wear resistance
Jewelry made of high-gravity tungsten alloy does not need to be polished even after long-term use, and its gloss is still new. In addition, in daily life with some objects bump, will not leave traces.
* High ultimate tensile strength
The ultimate tensile strength of tungsten alloy is much higher than that of other materials. Due to the low ultimate tensile strength of some materials, its application is often limited. Tungsten alloy can be used in some extreme environments. Ultimate tensile strength reflects real stress and engineering stress.
* High elongation
High density tungsten alloy shielding parts
Tungsten alloy with high specific gravity has high extensibility. Therefore, high-gravity tungsten alloy is often used in the production of armor-piercing bullets to improve the armor-piercing property of the bullets.
* High temperature resistance
Tungsten alloy has a higher melting point than other metal materials. In the high temperature environment, some metals may melt and are not suitable for use. And high specific gravity tungsten alloy will not melt even at high temperature environment.
* Low steam pressure
The boiling point of high specific gravity tungsten alloy at normal pressure is equivalent to the steam pressure at normal temperature.
* Non-toxic and pollution-free
High gravity tungsten alloy rod
Tungsten alloy is non-toxic and pollution-free, while lead is toxic. Therefore, high-gravity tungsten alloy can replace lead material.
* Good thermal stability
High specific gravity tungsten alloy has good thermal stability and will not form carbon slag in high temperature environment.
* High heat resistance
Tungsten alloy has higher heat resistance than other metal materials. At extremely high temperatures, other metal materials may have already melted, while high-gravity tungsten alloys will still not melt.
* Easy to process high-gravity tungsten alloy shielding parts
The composition of high-gravity tungsten alloy contains nickel, copper and iron. Therefore, high-gravity tungsten alloy has similar mechanical properties to steel and is easy to process. High specific gravity tungsten alloy can also be coated with anti-corrosion materials to enhance its corrosion resistance.
* Strong wind resistance
Tungsten Alloy
The density of high specific gravity tungsten alloy is large, and the quality of the fishing pendant made is also higher than that made of other materials, so that the sinking speed is faster and the efficiency of fishing is improved. High-gravity tungsten alloy fishing pendant makes it easier to feel the changes in the water.
High specific gravity tungsten alloy tube
* Strong corrosion resistance
Tungsten alloy has strong corrosion resistance and does not react with most acids and bases. It will not react with oxygen at room temperature.
* Strong radiation absorption
Compared with the shielding made of the same weight lead material, the volume of the high-gravity tungsten alloy shield is only 1/3 of that of lead, but the radiation absorption capacity is comparable to that of lead. A certain weight, higher density can be thinner thickness. The thickness of high-gravity tungsten alloy is higher than other materials, making the thickness smaller.
* Low shrinkage of metal
The density of high-gravity tungsten alloy material is large, so the extrusion die made of high-gravity tungsten alloy has a low shrinkage rate of metal when extruding metal.
* Impact resistance
High specific gravity tungsten alloy has good impact resistance, absorbs most of the energy at the moment of impact, and will not be easily broken
