High-Strength Wear-Resistant Silicon Nitride Ceramic U-Grooved Block Structural Component

High-Strength Wear-Resistant Silicon Nitride Ceramic U-Grooved Block Structural Component

Product Introduction

This product is an industrial structural component meticulously manufactured using advanced ceramic material—Silicon Nitride. It features a compact block-shaped geometry that integrates a through hole on one side and a U-shaped groove on the other, processed with precision machining and polishing to achieve the characteristic smooth ceramic surface and extremely high dimensional accuracy. Silicon Nitride ceramic is widely recognized as one of the advanced ceramics with the most outstanding overall properties, making it exceptionally suitable for extremely demanding industrial environments and providing a solid foundation for the superior performance of this structural component.

Core Advantages

• Exceptional Wear & Corrosion Resistance: High hardness results in a wear life several to dozens of times longer than traditional metal materials, and it resists most acids and alkalis.

• High Strength & Toughness: Rank among the best in ceramics for flexural strength and fracture toughness, capable of withstanding high loads and impact, preventing brittle fracture.

• Withstands Extreme Temperatures: Maintains shape and properties stable in environments exceeding 1200°C, resistant to oxidation and creep.

• Self-Lubricating & Non-Sticking: Non-wetting to common molten metals (e.g., aluminum, copper), reducing adhesion and extending service life.

• Lightweight & Insulating: Density is much lower than metals, enabling lightweight designs; possesses excellent electrical insulation properties.

Primary Applications

This product is widely used in precision industrial scenarios requiring wear resistance, high temperature resistance, corrosion resistance, and electrical insulation:

• Precision Machinery: Used as high-precision bearing balls, bearing seats, guides, sliders, and measuring instrument components.

• Automation & Fixturing: Serves as non-magnetic, wear-resistant fixtures, locating pins, and conveyor rollers.

• Semiconductor Industry: Applied in wafer handling arms, vacuum chucks, and heat treatment pedestals.

• High-Temperature Kiln Furniture: Used as kiln rollers, setters, and plates for supporting workpieces during sintering.

• Chemical & New Energy: Employed as corrosion-resistant valve parts, pump seals, and critical components in battery production lines.

Usage Instructions

1. Installation: Use a torque wrench during installation, tighten evenly according to the recommended torque to avoid damage caused by localized stress concentration.

2. Mating Materials: It is recommended to pair with harder, smooth-surface metals (e.g., hardened steel, stainless steel) or other ceramics for optimal wear resistance.

3. Avoid Impact: Despite good toughness, avoid severe mechanical shock or dropping from heights.

4. Clean Environment: Ensure the mounting surface and the ceramic component itself are clean and free of hard particles before use to prevent surface scratching or misalignment.
