The difference between high specific gravity high specific gravity tungsten beads and steel beads
Material aspect
Steel balls are generally made of carbon steel. The components of steel include carbon, iron, manganese, silicon, etc., which are simple and easy to obtain. High specific gravity high specific gravity tungsten beads are usually synthesized from tungsten, cobalt and other metal materials, and require complex processes such as high-temperature pressing and cooling. It can be seen that High specific gravity high specific gravity tungsten beads are superior to steel balls in terms of material.
Hardness
The hardness of High specific gravity high specific gravity tungsten beads is much higher than that of steel balls. This is because the hardness of tungsten steel reaches 89-93 on the Mohs hardness scale, while the hardness of steel balls is generally between HRC50-65. Therefore, in industrial production and entertainment sports, if a ball material that is more wear-resistant, more scratch-resistant, and more resistant to high temperatures is needed, then High specific gravity high specific gravity tungsten beads are more suitable than steel balls.
Density
Since the density of tungsten steel is higher than that of steel, High specific gravity high specific gravity tungsten beads with high density have more advantages than steel balls. During use, the weight of High specific gravity high specific gravity tungsten beads is relatively large, so it will be easier to achieve inertial blank forging, improve the quality of steel parts, and make forging forming more efficient.
Products Features
High specific gravity tungsten bead is characterized by high sintering density, good strength and plasticity, and ferromagnetism. It has good plasticity and machinability, good thermal conductivity and electrical conductivity, and has good absorption ability for gamma rays or X-rays.
Specific gravity
Generally, the specific gravity is 16.5-18.75g/cm3;
High strength
Tensile strength is 700-1000Mpa;
Strong ability to absorb radiation
30-40% higher than lead
Large thermal conductivity
The thermal conductivity of tungsten alloy is 5 times that of mold steel;
The thermal expansion coefficient is small
Only 1/2-1/3 of iron or steel
Good electrical conductivity
Due to its good electrical conductivity, it is widely employed in the welding and lighting industries;
Has good weldability and processability
Products Applications
Tungsten alloys have replaced lead in military products because their higher density allows them to retain their shape better, even under extreme conditions. While uranium offers comparable densities, its volatile nature and the special licensing requirements required for radioactive materials make processing difficult. Tungsten alloy is a green and environmentally friendly metal material that does not produce toxic substances during use and production and processing. As the military industry continues to expand, the impact on the environment after the use of military weapons must also be taken into consideration. The environmental performance of tungsten alloy makes its advantages in the military field more and more prominent. For instance, engine accessories made of tungsten alloy, fin discarding sabots, submersible counterweights, etc.
Grinding function
High specific gravity tungsten beads are a widely used grinding media in grinding materials and have high hardness and wear resistance. It is widely used in the fields of preparing ceramics, coatings, plastics, rubber, material surface treatment, pigments, paints and other fields.
Wear-resistant function
High specific gravity tungsten beads have very high hardness and compressive strength and can withstand extremely high rotation speeds and impact forces. Therefore, they are widely used when grinding the surfaces of hard materials such as steel, castings, refractory materials, ceramics, quartz, and glass.
Conductive function
High specific gravity tungsten beads have good electrical conductivity, so they can be used as highly conductive powder metallurgy materials. It is widely used in graphite electrodes, electronic devices, batteries and other fields.
Sealing function
High specific gravity tungsten beads are light in weight and high in density, so they have good sealing properties. It is widely used in the fields of airtight container sealing, valve packing, pipeline sealing and other fields.
Production Process
Add cobalt element to tungsten alloy powder to obtain tungsten alloy beads raw material mixed powder;
Mix the tungsten alloy beads raw material mixed powder with glue and granulate, then screen and classify to obtain granulated materials of different particle size grades;
The granulated materials of different particle size grades are molded according to the same particle size grade to obtain a tungsten alloy bead compact;;
Thermal degreasing of tungsten alloy bead compacts;
Sintering to obtain tungsten alloy bead sintered billet;
Tungsten alloy beads are obtained by grinding the sintered billet of tungsten alloy beads and subjecting it to stress relief annealing treatment.
By adding cobalt element to the tungsten alloy powder, the wetting performance of the tungsten particles is improved and the sintering activity is increased. By adding glue, granulating and screening and classifying, the fluidity of the granulated material is improved, and the tungsten alloy bead compact is reduced. Unit weight and size fluctuations, combined with thermal degreasing and stress relief annealing, avoid compact damage and performance deterioration, and improve the molding quality and production efficiency of tungsten alloy beads.
FAQ
Common Problem
What are high specific gravity tungsten beads?
high specific gravity tungsten beads are small metallic spheres made from tungsten metal. They are commonly used as a weight in fishing flies and lures.
What are the advantages of using high specific gravity tungsten beads in fly fishing?
high specific gravity tungsten beads are significantly denser than other bead materials like brass or lead. This allows for a much smaller bead size to be used while still providing the same weight and sink rate. Additionally, tungsten is non-toxic, making it a safer option for both anglers and the environment.
What other applications do high specific gravity tungsten beads have?
high specific gravity tungsten beads are also used as a weight in jewelry making, particularly in men's necklaces and bracelets. They can also be used in ball bearings, counterweights, and radiation shielding.
What are the benefits of using tungsten over traditional weight materials like lead?
Tungsten is non-toxic and poses fewer health risks compared to lead. It is also significantly denser, meaning smaller amounts can be used to achieve the same weight or density. Additionally, tungsten has a higher melting point and is more resistant to corrosion, making it a more durable material overall.
