Design considerations should minimize tensile stresses and impact loads.<\/li>\n<li><strong>Machining Complexity:<\/strong> Its extreme hardness makes SiC very difficult and costly to machine in its densified state, necessitating diamond tooling and specialized equipment. This reinforces the importance of near-net shape forming.<\/li>\n<li><strong>Thermal Shock Sensitivity (for some grades):<\/strong> While generally good, extreme rapid temperature changes can cause cracking in certain SiC compositions. Careful material selection and thermal management are key.<\/li>\n<li><strong>High Manufacturing Costs:<\/strong> The raw materials and processing methods for SiC can be more expensive than conventional materials, though the long-term cost savings from reduced wear often outweigh the initial investment.<\/li>\n<\/ul>\n<h2>How to Choose the Right SiC Supplier<\/h2>\n<p>Selecting a reliable supplier for custom silicon carbide products is crucial for project success.
