Aluminum castings feature low production costs and excellent process‑ability. Their remelting and recycling conserve resources and energy, which accounts for the enduring application and development of aluminium‑based materials.
Special‑type processes and equipment adopted for aluminium castings include metal mould casting, sand‑lined metal mould casting, lost‑foam casting, sand casting, die casting, low‑pressure casting, investment casting, permanent‑mould casting and continuous casting.
Boasting low density, high specific strength, corrosion resistance and a host of other properties, aluminium castings will see broader‑ranging applications across aerospace, automotive, machinery and other industries. Particularly within the automobile industry, replacing steel and iron castings with aluminium castings constitutes a long‑term development trend for fuel‑consumption reduction and higher energy‑use efficiency.
Priority shall be given to developing pollution‑free, high‑efficiency and user‑friendly molten‑alloy refining technologies. To further enhance material performance and maximise material potential, tailored aluminium‑alloy grades can be deployed to satisfy performance demands under diverse working‑conditions. Research on melting procedures shall be strengthened; development work on die‑casting, squeeze‑casting and supporting technologies will be carried out. Research‑and‑development shall also be advanced to perfect processes and relevant technologies for aluminium castings.
