To ensure that your finished products are strong and durable, you’ll need to use specific types of metals. Discover the kinds of metals that foundries use in metal casting below.
What Is a Foundry
Before you learn about the kinds of metals that foundries use in metal casting, you’ll need to know what a foundry is. A foundry is a factory that specializes in metal casting.
Metal casting is the process of molding a metal into a specific shape. To mold a metal into a particular shape, a foundry melts the metal until it changes from a solid to a liquid state. Then, they pour it into a mold, which is also called a cast.
After the metal cools, it takes the shape of the cast, thus creating the finished product. Many industries use these finished products to create buildings, bridges, artwork, machines, and much more.
Business Selling FAQ
Bronze
Because bronze and bronze alloys are ductile metals that can change shape easily, foundries often use them for metal casting. Additionally, bronze expands when it encounters heat and contracts when it encounters cold, so many foundries find that this metal is easy to remove from a cast after it cools and contracts.
A few other properties of bronze that make it a popular metal for casting are its durability, corrosion resistance, and ability to conduct electricity with ease.
Steel
Foundries use both stainless steel and carbon steel for metal casting. Stainless steel and carbon steel are both metal alloys, which means that they are combined with other metals.
Stainless steel is known for its strength and corrosion resistance, while carbon steel is known for its weldability and strength. People often use carbon steel for railroad tracks, pipes, automotive parts, and tools.
On the other hand, people use stainless steel for medical equipment, architecture, and airplane parts.
Aluminum
Aluminum is a very lightweight and flexible metal that you’ll often find in airplane parts, cables, and power systems. You’ll also find aluminum in electronics, high-rise buildings, and household appliances.
Due to its corrosion resistance, light weight, and ability to conduct electricity, aluminum is a very popular metal to use for many applications.
Iron
You’ll often find that many foundries use iron and iron alloys for metal casting. Iron is strong, tough, durable, and resistant to corrosion, so it’s an excellent metal to use for all kinds of industrial applications.
Engineers and architects often use iron for machinery, tools, automotive and airplane parts, buildings, and bridges.
Keep in mind that there are many other metals that foundries can use for metal casting. Iron, aluminum, steel, and bronze are simply some of the most common and useful metals that you’ll come across in a foundry.
