Specifications of High Performance 3mm 4mm 5mm 10mm Silicon Nitride Si3N4 Ceramic Balls

High-performance silicon nitride (Si3N4) ceramic balls are precision-engineered components designed for demanding industrial applications. These balls come in diameters of 3mm, 4mm, 5mm, and 10mm. They are made from advanced ceramic material, combining exceptional mechanical properties with chemical stability. Silicon nitride ceramic balls are ideal for use in high-stress environments due to their superior hardness, wear resistance, and thermal shock resistance.

The material’s low density reduces rotational inertia, making these balls suitable for high-speed applications. Silicon nitride outperforms traditional materials like steel or alumina in extreme conditions. It maintains strength at temperatures up to 1200°C. The ceramic structure resists oxidation and corrosion, ensuring long-term reliability in aggressive chemical or humid environments. Electrical insulation properties prevent current leakage, expanding their use in electronics and electric machinery.

Each ball size serves specific purposes. The 3mm and 4mm balls are commonly used in precision instruments, dental tools, and small bearings. The 5mm balls fit applications like automotive fuel systems, pump components, and aerospace actuators. The 10mm balls handle heavy-duty tasks in industrial machinery, wind turbines, and medical equipment. All sizes undergo strict quality control to meet dimensional tolerances within ±0.001mm. Surface roughness is maintained below Ra 0.05μm for smooth operation.

Silicon nitride’s fracture toughness exceeds other ceramics, reducing the risk of sudden failure under impact. Its self-lubricating properties minimize friction, lowering energy consumption in rotating systems. These balls are compatible with vacuum environments, making them valuable in semiconductor manufacturing. They are non-magnetic, avoiding interference in sensitive devices like MRI machines.

Manufacturing follows ISO 3290 and ASTM F2094 standards. Material purity exceeds 99.9%, with minimal porosity for consistent performance. Testing includes hardness checks (HRA 90-92), density measurements (3.2-3.3 g/cm³), and load capacity verification. Custom sizes or surface treatments are available for specialized needs. Packaging ensures protection during shipping, with anti-static materials for contamination-sensitive applications.

Silicon nitride ceramic balls offer a cost-effective solution for industries prioritizing durability and efficiency. Their combination of lightweight design, thermal stability, and mechanical strength makes them a preferred choice for engineers seeking reliable performance in harsh conditions.
