                Q1: Why choose alumina ceramic instead of aluminum heat sinks?<\/p>\n

                Aluminum offers higher thermal conductivity, but alumina ceramic provides superior electrical insulation, corrosion resistance, and high-temperature stability, making it ideal for high-voltage and semiconductor environments.<\/p>\n

                \n

                Q2: Can customized holes and shapes be processed?<\/p>\n

                Yes. CNC machining, laser cutting, drilling, grooves, and custom structural processing are available according to customer drawings.<\/p>\n

                \n

                Q3: Is the plate suitable for semiconductor equipment applications?<\/p>\n

                Yes. High-purity alumina ceramics are widely used in semiconductor processing systems because of their dimensional stability, insulation performance, and resistance to harsh operating conditions.<\/p>","protected":false},"excerpt":{"rendered":"
