History & Manufacturing Process of Cast Aluminum

The history of cast aluminum dates back to ancient times when aluminum was first used in various applications. However, the production of aluminum as a pure metal was only possible in the 19th century when it was isolated through the electrolysis of aluminum oxide (alumina).

Aluminum is hardened by melting it and pouring it into a mold. It solidifies and takes on the shape of the mold. There are several methods for casting aluminum, including sand casting, die casting, and permanent mold casting.

Sand casting is a traditional method of casting aluminum using a mold made from sand. The aluminum is melted and poured into the mold, where it solidifies and takes on its shape. Sand casting is relatively simple and inexpensive, but it is unsuitable for producing high-precision parts.

The die casting process is a more precise method of casting aluminum that uses high pressures and temperatures to inject molten metal into a mold. This process produces parts with high dimensional accuracy, a smooth surface finish, and very little porosity.

Permanent mold casting is similar to die casting, but the mold is made from a durable material such as steel or cast iron. This process is suitable for producing parts with high precision and a smooth surface finish.

Today, aluminum is widely used in many industries, including automotive, aerospace, construction, and consumer products. It’s strong enough to be used in structural applications and lights sufficient in manufacturing. Also, its corrosion resistance makes it ideal for many different applications.
