There are differences in strength between CNC die-cast aluminum alloy and CNC aluminum alloy, which mainly depends on factors such as material composition and process parameters.
1. Material composition and process parameters: During the die-casting process of die-cast aluminum alloy, the molten metal cools rapidly to form a dense microstructure and uniform grain size, thereby improving the mechanical properties of the material. In contrast, CNC machining is obtained by cutting and may be affected by the heat and stress generated during the machining process, which may cause defects inside the material and reduce the strength.
2. Processing method: CNC machining is a mechanical processing method that processes metal billets through computer numerical control machine tools to achieve high-precision and high-efficiency processing goals. Die-cast aluminum alloy, on the other hand, injects molten metal into the mold cavity under high pressure and forms castings by cooling and solidification.
1. Die-cast aluminum alloy: Due to its high strength and excellent physical properties, it is widely used in automotive, aerospace, machinery manufacturing and other fields, especially those parts that need to withstand high loads and impacts.
2. CNC aluminum alloy: Due to its high precision and flexibility, it is widely used in various fields requiring precision processing, such as watch parts, precision instruments, etc.
