There are both advantages and disadvantages to using materials such as Inconel or ceramics for CNC turned parts. Inconel is known for its excellent strength at high temperatures, making it ideal for aerospace and automotive applications. However, it is also difficult to machine, requiring specialized tools and processes that can increase costs. Ceramics offer high hardness and corrosion resistance, making them suitable for medical devices and electrical insulators. However, their brittleness requires careful handling and machining, which can limit design options and increase manufacturing complexity.
