Aluminum Silicon (AlSi) Packaging Material

Product Overview

Aluminum Silicon (AlSi) alloy is a lightweight, high thermal conductivity material with a controllable low thermal expansion coefficient. Due to its excellent machining properties, such as ease of CNC machining, electroplating, and welding, AlSi alloy is widely used in the electronic packaging industry, especially for high-temperature, high-power devices with demanding thermal management requirements. It can replace traditional packaging materials like AlSiC, copper tungsten (CuW), and copper molybdenum (CuMo), providing superior performance and cost-efficiency.
