Basic Knowledge The Role of Aluminum in Light Metal Casting

Author / Editor: Simon Morrison / Nicole Kareta

Aluminum is one of the most valuable raw industrial materials due to its versatility, low weight, and high durability. It is used to produce castings for a huge range of products and components. In this article, we’ll take a closer look at the history of aluminum production, the properties of aluminum, and why aluminum plays a crucial role in light metal casting.

Currently, the main players in the worldwide aluminum industry include Russia’s UC RUSAL, the Aluminum Corporation of China (CHALCO), the UK’s Rio Tinto, and the US-based Alcoa Corporation. China is far and away the biggest global market for aluminum. With the huge amounts of urbanization and industrial development being undertaken by China, they are expected to remain both the world’s biggest consumer and producer of aluminum for years to come.
As well as the increased demand for aluminum from the Chinese market, worldwide factors such as the rise of electric vehicles, the increased production of solar panels, and the demand for packaged foods have seen the consumption of aluminum skyrocket.

However, recent industry growth has been hampered because of the impact of the COVID-19 pandemic. Many manufacturing sectors have slowed output due to shortages of workers and decreased demand from the automotive and aerospace industries. Future growth is also expected to be restrained by the introduction of more stringent environmental regulations and tighter emissions standards.
