Tungsten Carbide Jar and Ball

Tungsten carbide balls or tungsten steel balls consist of cemented tungsten carbide. Tungsten carbide has high hardness, wear, corrosion resistance, durability, and other advanced properties over steel ball products. Cemented carbide balls in the Tungsten carbide family include blank balls, fine grinding balls, punching balls, bearing-esque balls, valve balls, non-magnetic balls, monel balls, through-holes, metering, scratching pen balls, and, as the name suggests, pen balls.

Tungsten Carbide Balls and their accompanying tools demonstrate widespread versatility and application within tools of precision hardware such as valves, molds, bearings, die castings, punching, fishing gear, and their counterparts. These parts are manufactured by bonding cobalt-containing metals with ferrous carbide and sintering those matrices with tungsten carbide. Tungsten carbide bonds. Unquestionably, these particles retain lower surface roughness, uniform fractures, and are void of supreme efficacy and finer pores compared to steel balls, making them requisites in ballpoint pens and other writing instruments.

Besides, due to their properties, tungsten carbide balls do not have magnetic properties, making them useful in a diverse range of applications that require avoidance of magnetic interference. Research and development in manufacturing and application technology have led to cemented carbide being used in thermal and sand wells. The production process for cemented carbide balls includes the following steps: powder making, formulation, wet grinding, mixing, crushing, drying, screening, adding molding agent, re-drying, screening to obtain a mixture, granulation, cold isostatic pressing, molding, sintering, rough molding, packing, and finally warehousing.

- Industrial Machines: Carbide jars are a component of industrial machinery, like a milling, grinding, and cutting machines, as they require extreme strength and resistance to wear.

- Chemical Processing: Due to a material's need for corrosion resistance, jars are often utilized in chemical processes.

- Pump Impellers: The construction of pump impellers is made from tungsten carbide jars because the abrasive materials and high-pressure environments of the pump permit it.

- Heat Resistance: Without the loss of strength or structural integrity, tungsten carbide jars can operate in extremely high temperature environments.
 

- Ball Bearings: The manufacturing of ball bearings, which are highly stressed and need to withstand wear, is done using tungstencarbide spheres.

- Hammers and Tools: The ability of tungsten carbide to withstand piercing and impact leads to its usage for making forging hammers and impact hammers.

- Abrasives: For various abrasive tools like ball grinding mills, tungsten carbide balls have great hardness and withstand abrasion, which makes them employed.

- Magnetic Applications: Certain tungsten carbide spheres are magnetically coated, which allows their use in magnetic devices and sensors.

Tungsten-carbide hardness: Tungsten Carbide is virtually unassailable to scratching or indentations, in the same way diamonds are, only due to its expected surpassing of the Vickers hardness value.

Wear resistance: Scratching damage is arguably some of the most irreversible and painful damage a material can take, but units of tungsten carbide are spared by unmatched toughness, which grants it unparalleled ability to endure.

Substance resilience: The melting point does not change; thus, extreme conditions such as 2870 degrees Celsius (or 5280 degrees Fahrenheit) will not result in the tungsten carbide becoming molten.

Corrosion resistance: It's a known fact that in comparison to other metals, tungsten carbide does possess low corrosion resistance, but when exposed to numerous chemicals, especially at moderate temperatures, it does withstand the structural value.

Dimensional accuracy: The dimensional tolerances of tungsten carbide cans and balls are strictly controlled to ensure high precision.
Surface quality: The surface is smooth, without scratches, cracks, oxidation and other defects, and can be polished to further improve the surface finish.
Composition control: The ratio of tungsten carbide and cobalt is strictly controlled to ensure the high performance of the material.
Performance testing: The finished product is tested for hardness (such as Vickers hardness), tensile strength and wear resistance to ensure that it meets the standards.

1. What is a tungsten carbide ball?

Tungsten carbide balls, belonging to the class of metallic alloys, are specifically designed for industrial use, marked by nanometer precision in their dimensions. Tungsten carbide balls merge tungsten with carbon atoms to produce a mass that has a spherical shape. Due to their unique properties, they become gradually more useful to aid the productivity in machines fro,m high durability and ultra-hard industrial uses.

2. What are the main characteristics? -Controlled Properties Hardness: 90-92 HRA, which is greater than steel and one notch lower than diamond. Density: Approximately 15 g/cm, making it denser than steel, ~14.9. Corrosion Resistance: Good except in strong oxidizing acids. Heat Resistance: Stable up to 600 degrees Celsius. Magnetic Properties: Usually non-magnetic unless it possesses a nickel/cobalt binder, becoming more magnetic.

3. What are the application areas? Bearings and Valves: Ball and gate valves in chemical pumps, along with high-pressure oil and gas pumps, rough and abrasive sectors. Precision Tools: Dental instruments, gages, ball screws. Everyday Items: Fishing reel bearings and ballpoint pen parts. Aerospace: Gyroscopes and directional systems.

4. Why select tungsten carbide over steel or ceramics?

In comparison to regular steel alloys, tungsten carbide balls are about 3-5 times stronger when wear resistance is taken into account. For use in diverse ultra-high-speed machines, tungsten carbide balls are ultra-durable and gamble-free.

When compared to ceramics, tungsten carbides are not as good an insulator. However, when impact and density are taken into consideration, tungsten carbide is far superior.
 

5. Are there any limitations?

While tungsten carbide is more economically sensible in the long term, not only is it more expensive than steel, it is also known to be extremely brittle, shattering upon forceful impacts.

Challenges in Processing: Requires grinding/polishing with diamond tools.

6. What processes are involved in making it?

WC is blended and compacted with cobalt powder into a billet.

Sintering at 1400 degrees.

7. What specifications and grades are available?

Dimensions: 0.5-50mm in diameter (custom-made).

Grade: Based on cobalt content (e.g., 6% cobalt for hardness, 10% cobalt for toughness).

8. What is the MOQ?
A: Depends on quantity; generally, no MOQ limit.

9. How to pay for it?
A: A bank transfer (T/T) will be acceptable.

10. What is the delivery time?
A: around 7-20 days, which depends on the quantity and production.

11 . What is the package?
A: cartoon case or plywood case.

1 2. What is the lead time?
From the order placed to cargo receiving will take around 10-25 days.

13. What is the delivery method?
A: Generally, we send cargo by UPS, DHL, or FedEx. Also, we can send by sea to a seaport or by air to the closest airport.
