Design Considerations for Custom SiC Products

Designing with silicon carbide requires a specialized approach due to its unique material characteristics. Proper design can significantly impact performance, manufacturability, and cost. Key considerations include:

• Bevennoù Geometriezh: Avoid sharp internal corners, thin walls in highly stressed areas, and abrupt changes in cross-section, as these can create stress concentrations due to SiC’s inherent brittleness.
• Espessura da parede: Maintain uniform wall thickness where possible to prevent differential cooling during processing, which can lead to warping or cracking.
• Poentoù pouez: Identify and minimize stress points through strategic design, such as adding fillets or radii to corners.
• Tolerâncias: While SiC can achieve high precision, overly tight tolerances can increase manufacturing complexity and cost. Design with achievable tolerances in mind.
• Barregezh da usinañ: Consider the machinability of the chosen SiC grade during design. Green machining (before sintering) is easier than hard machining (after sintering).
• Mounting and Joining: Plan for how SiC components will be mounted or joined to other materials, considering thermal expansion differences and bonding methods.

Tolerance, Surface Finish & Dimensional Accuracy in SiC Manufacturing

Achieving precise tolerances and specified surface finishes is critical for the performance of custom SiC components.
