Product Name: Tungsten Carbide Ball / Hard Alloy Ball
Product Overview:
Our Tungsten Carbide Balls are precision-engineered using high-quality refractory metal carbides (WC, TiC) with cobalt, nickel, or molybdenum as binders through advanced powder metallurgy processes. These balls offer exceptional hardness, wear resistance, and corrosion resistance, combined with superior dimensional accuracy. They are ideal for demanding applications in mechanical, chemical, aerospace, and precision instrumentation industries.
Key Advantages:
Superior Wear Resistance & Strength: Manufactured with vacuum sintering and hot isostatic pressing (HIP), ensuring uniform density, high hardness, and long-term durability even in high-temperature and harsh environments.
Precision Roundness: Ground to achieve high sphericity and low surface roughness, meeting stringent requirements for precision bearings, mechanical seals, and valves.
Customizable Specifications: Available in a wide range of diameters, sizes, and hardness grades to meet diverse engineering and industrial needs.
Reliable Performance: Excellent resistance to deformation and wear, reducing maintenance and operational costs.
Typical Applications:
1.Precision Components: Punching, stretching, precision bearings, valve balls, mechanical seal balls
2.Industrial Equipment: Chemical pumps, hydraulic systems, spraying equipment
3.Grinding & Measurement: Grinding media, precision instruments
4.Other High-Wear Applications: Pen manufacturing equipment, aerospace components, automotive parts, and other high-strength wear-resistant components
Technical Specifications (Customizable):
Diameter Range: Φ0.25-Φ100 mm
Hardness: HRA 87-92
Density: 13.8-14.9 g/cm³
Roundness Tolerance: ≤0.005 mm
Surface Roughness: Ra ≤ 0.1 μm
Manufacturing Process Highlights:
Powder → Material Mixing → Wet Milling → Blending → Crushing → Drying → Sieving → Add Binders → Granulation → Pressing / Cold Isostatic Pressing (CIP) → Shaping → Sintering → Rough / Precision Grinding → Packaging → Storage
1. Uniform Density and Compact Structure
Cold Isostatic Pressing (CIP) can be applied when necessary to ensure highly uniform density throughout the tungsten carbide balls, effectively minimizing internal structural variations. This significantly enhances product consistency and long-term reliability.
2. High-Density HIP Sintering
High-Pressure Sintering (HIP) drastically reduces internal porosity, producing a denser microstructure. This improves wear resistance, impact strength, and overall service life, making the balls suitable for high-load and demanding working conditions.
3. Optional Passivation Treatment
Surface passivation can be performed according to customer requirements to enhance corrosion resistance and extend service life.
4. Wide Range of Grades and Properties
Various tungsten carbide grades are available, such as YG6, YG8, YG10X, YG15, and YG20, with hardness ranging from HRA 89.5 to 92 and bending strength up to 4000 MPa. These balls are widely used in bearings, valves, grinding media, precision machinery, and other wear-resistant components in high-demand applications.
5. High Precision Customization
Balls can be customized in diameter and precision grade according to customer requirements, meeting the needs of high-precision assemblies and special operating conditions.
6. Multiple Precision Grades
Precision grinding is available in grades G5, G10, G25, G50, and G100 to meet international standards and diverse application requirements for roundness and dimensional accuracy.
7. 24/7 Professional Support
We provide around-the-clock technical consultation and after-sales support, ensuring fast response to customer needs and reliable, continuous cooperation.
