It wasn’t until the 19th century when aluminum was discovered in its purest form – thanks to the modern advancements in chemistry, electricity, and scientific exploratory methodology. Since then, the century and a half long journey has led to it becoming a highly coveted metal in various industries. Two reasons aluminum is the second most popular metal in manufacturing is because it’s weather-proof, and it’s widely available and therefore priced less than brass for instance.
Astronomical Gain in Popularity
Did you know that the use of a form of aluminum or compound called alum was recorded back in the 5th Century? It was considered a precious metal and was used in medicine and manufacturing fire-resistant coating, among others. Resembling silver, aluminum was also used to make jewelry, tools, and other ornamental pieces. It was certainly a favorite metal in ancient times. Centuries later, when pure aluminum and aluminum alloys became a possibility, aluminum casting became a norm. Lightweight, low density, and easy malleability of aluminum made it easy to cast. Raw aluminum or ingot is melted into liquid and cast into incredibly detailed designs that deliver aesthetic appeal and sturdiness in one product.
Uses in Greater Quantities
One of the most popular questions NASA receives about their space shuttles is why they don’t use titanium. The lighter weight of aluminum, along with the strength it boasts, allows the spacecraft to carry a heavier payload. Found on the Earth’s outer crust, aluminum is primarily used in the United States in Transportation (trucks, airplanes, and warships).
Metal casting in aluminum has taken the foundry industry by a storm since its discovery. The thickness of casting in metal is lightweight, polishes into a brilliant finish, and it doesn’t rust.
