High beryllium aluminum alloy, also called Locke alloy, is an aluminum-based alloy. It is produced using powder metal extrusion and rolling processes. Used in missiles, rockets, ultra-high-speed structural parts, aircraft brakes and electronic computer disk drives. High-beryllium aluminum alloy has many excellent properties such as light weight, high specific strength, high specific stiffness, good thermal stability, high toughness, corrosion resistance, and combines the low density of plating with the easy processability of aluminum. It is widely used in the aviation and aerospace industries, It has been widely used in computer manufacturing, automobile industry and high-precision and high-speed welding machine manufacturing industry, and has become an increasingly important new material.
