Do you know the physical properties of high density tungsten alloys?

Tungsten Heavy Alloys are a type of alloy based on tungsten (with a W content of 85-99%) and composed of elements such as Ni, Cu, Co, Mo, Cr, etc.

According to the composition characteristics and uses of the alloy, it is divided into W-Ni Fe, W-Ni Cu, W-Co, W-WC Cu, W-Ag and other main series, with a density of up to 16.5-19.0g/cm3, which is known as a high density alloy by the world.

It also has a series of excellent characteristics, with a specific gravity of 16.5-18.75g/cm3, high strength, tensile strength of 700-1000Mpa, strong radiation absorption ability, 30-40% higher than lead, and a large thermal conductivity, which is 5 times that of mold steel; Low coefficient of thermal expansion: only 1/2-1/3 of iron or steel, good conductivity; It has good weldability and processability. Given the excellent functions mentioned above, high density alloys are widely used in industries such as aerospace, aviation, military, oil drilling, electrical instrumentation, and medicine.

High density Tungsten Alloys have many excellent properties. Its physical properties include the following:

High density and high hardness: It is called a high density Tungsten Alloy because of its high density. The tungsten content in high density tungsten alloys ranges between 90% and 97%. The density of high density tungsten alloy is 16.85-18.85g/cc. High density tungsten alloy can be made into shielding components. Compared with shielding components of the same weight, the radiation absorption capacity of high density Tungsten Alloy Shielding components is equivalent, while the volume is only 1/3.

Small size and high melting point: Tungsten has the highest melting point among all metals (at 3410 ° C) and a high tensile strength Z. Compared with fishing pendants made of other materials, fishing pendants made of high density tungsten alloy have a smaller volume. Therefore, there is no need to hang too many tungsten alloy fishing pendants on the fishing line.

High wear resistance: Jewelry made of high density tungsten alloy does not require further polishing even after long-term use, and its glossiness remains brand new. In addition, collisions with certain objects in daily life will not leave any marks.

High ultimate tensile strength: The ultimate tensile strength of high density tungsten alloys is much higher than that of other materials. Some materials often limit their application due to their low ultimate tensile strength. High density tungsten alloys can be used in some extreme environments. The ultimate tensile strength reflects both real stress and engineering stress.

High extensibility: High density tungsten alloys have high extensibility. Therefore, high density tungsten alloys are commonly used in the production of armor piercing projectiles to improve their armor piercing performance.

High temperature resistance and good thermal stability: The melting point of high density tungsten alloy is higher than that of other metal materials. In high-temperature environments, some metals may melt and are not suitable for use. And high density tungsten alloys do not melt even in high-temperature environments

Non toxic and pollution-free: High density tungsten alloys are non-toxic and pollution-free, while lead is toxic. Therefore, high density tungsten alloys can replace lead materials.

High heat resistance and easy processing: The composition of high density tungsten alloys contains nickel, copper, and iron, which have higher heat resistance than other metal materials. Therefore, high density tungsten alloys have mechanical properties similar to steel and are easy to process. At extremely high temperatures, other metal materials may have already melted, while high density tungsten alloys still do not melt.

Strong wind resistance and low metal shrinkage: High density tungsten alloys have high density and low metal shrinkage. The quality of the made fishing pendant is also higher than that of other materials, resulting in faster sinking speed and improved fishing efficiency. High density tungsten alloy fishing pendant can make it easier for you to feel the changes in water conditions.

Strong corrosion resistance: High density tungsten alloys have strong corrosion resistance and do not react with the vast majority of acids and alkalis. It will not react with oxygen at room temperature.

Strong radiation absorption ability: Compared with shielding components made of lead material of the same weight, the volume of high density tungsten alloy shielding components is only one-third of that of lead, but the radiation absorption ability is equivalent to that of lead. A certain weight and higher density can result in a thinner thickness. The thickness of high density tungsten alloys is higher than other materials, resulting in a smaller thickness.
