Cast vs. Billet Aluminum: Process Differences:
- Cast Aluminum is produced through a casting process, where molten aluminum is poured into molds, making it ideal for parts with complex shapes and varying thicknesses. This method provides good strength and corrosion resistance.
- Billet Aluminum, on the other hand, is crafted from a solid block of aluminum through forging and machining. This process results in higher strength and durability, making it suitable for high-precision and demanding applications.
