FAQ – Tungsten Carbide Balls

Q1: What are tungsten carbide balls used for?

Tungsten carbide balls are used in applications that require extreme hardness and high wear resistance, such as valves, pumps, bearings, measuring instruments, and other components operating under severe abrasion, corrosion, or high temperature conditions. Tungsten alloy balls are also employed in precision instruments, aerospace components, and heavy-duty industrial machinery.

Q2: What is the material composition of your tungsten carbide balls?

The balls are made from tungsten carbide with approximately 94% WC and 6% nickel-based binder, forming a very hard and tough composite structure. This composition ensures high load-bearing capacity while maintaining dimensional stability.

Q3: What are the key mechanical properties?

At 20?°C, typical transverse rupture strength is about 2600?MN/m2, and compressive strength is around 6870?MN/m2, providing excellent durability. The density is approximately 14.968?g/cm3, significantly higher than steel, which is beneficial where weight and inertia are important.

Q4: What size range can you supply?

Standard sizes range from 0.8?mm (1/32") up to 63.5?mm (2?1/2"), covering very small precision tungsten balls for sale to large heavy-duty sizes. Custom diameters are available upon request for specialized applications.

Q5: What hardness can tungsten carbide balls reach?

The hardness typically ranges from HRA90–92, providing exceptional resistance to wear, deformation, and surface damage under heavy load. Tungsten steel balls are particularly suited for extreme operating conditions where surface integrity is critical.

Q6: What precision grades are available?

Tungsten carbide balls can be supplied from G10 to G1000, allowing selection from ultra-precision tungsten carbide spheres to commercial grades according to application and cost considerations.

Q7: How do tungsten carbide balls perform at high temperature and in corrosive environments?

They maintain hardness and strength at elevated temperatures and exhibit excellent resistance in abrasive, corrosive, and poorly lubricated conditions, making them a superior alternative to steel balls in harsh environments.

Q8: Are these balls magnetic?

Tungsten carbide balls with a nickel-based binder are only slightly magnetic, which can be beneficial in applications where low magnetism is preferred, such as certain electronic and measurement devices.

Q9: What is the thermal expansion behavior?

The low expansion rate of tungsten carbide helps maintain dimensional stability and precision over temperature fluctuations, making tungsten balls reliable in precision assemblies.

Q10: When should tungsten carbide balls be chosen instead of steel balls?

They are recommended for applications involving high abrasion, impact, corrosion, elevated temperatures, or where long service life and minimal wear justify a higher initial cost.

Q11: Can you provide custom sizes or grades?

Yes, custom diameters, grades (G10–G1000), and quantities can be produced after technical evaluation. Drawings or specifications can be submitted to Eurasian, a trusted tungsten carbide ball exporter and tungsten carbide ball wholesaler, for confirmation and quotation.
