High-Strength, High-Temperature Resistant U-Shaped Silicon Carbide Ceramic Structural Component

Product Introduction

This product is a high-purity silicon carbide ceramic U-shaped structural component manufactured through an advanced reaction bonding process. It features a dense dark gray-black appearance with a smooth, finely granular texture achieved by precision grinding. Designed with a classic U-block structure and high-precision symmetrical grooves on both sides, it ensures alignment and stability in complex mechanical assemblies. Integrating the exceptional physical and chemical properties of silicon carbide ceramic, this component is engineered to perform in extreme and harsh operating conditions, making it an indispensable critical base element in high-end industrial equipment.

Core Advantages

• Exceptional High-Temperature Resistance: Maintains strength in inert atmospheres up to 1600°C, with excellent oxidation resistance and no softening or deformation.

• Superior Corrosion Resistance: Offers outstanding resistance to most acids, alkalis, and molten salts, ensuring a long service life.

• Excellent Wear Resistance: Possesses high hardness, second only to diamond, with wear resistance far exceeding that of metals and other ceramics.

• High Strength & Stiffness: Features very high flexural strength and modulus of elasticity, capable of withstanding heavy loads and impact, ensuring structural stability.

• Outstanding Thermal Shock Resistance: Low thermal expansion coefficient and high thermal conductivity enable it to withstand rapid temperature changes without cracking.

Primary Applications
