Alloy and Rare Alloy Stampings
Metal stamping serves an important purpose. Making machined parts involves several steps. The process starts with design and ends with the finished products. Although stamped parts consist of many different materials, the most popular are alloys.
What Exactly Is Alloy Stamping?
The best way to define alloy stamping is by describing the process. An engineer works with a client to design a specific machined part. (Although sometimes the part is already designed, and the client just needs someone tomake them.) These parts can be for some different industries – from marine (shipbuilding) to automotive. They create engines, structural sections, and more. Once the engineers complete the part, the next step involves choosing an alloy. Some are stronger than others, which is why this is an important decision. The part needs to stand up to a certain amount of wear and tear.
After the big decisions, the parts are made using a special stamping machine. The metal is sometimes heated to help the fabrication process. Other time, it’s not. The process depends on the metal used and the type of part.
Alloys are favored over pure metals because they are much stronger. Combining two different types of metals changes the chemical composition of them both. Heat treating helps this process. The combination leads to stronger sheet metal, which makes equally sturdy parts.
Alloy Stamping Metals
Alloy stamping uses some different types of metals, from galvanized steel to stainless steel. Some companies make metal parts from standard materials, like copper and aluminum. These aren’t alloys, since they consist of one single type of metal. For the metal to be an alloy, it needs to be a blend of materials.
What about Rare Alloys?
Some types of alloys are considered rare. Rare alloys consist of a unique blend of materials with special properties. The machines that make parts from them need to be built to handle these alloys. One example of a rare alloy is Hastelloy®. This metal consists of nickel, chromium, iron, and molybdenum. The turbine industry uses it quite a bit because it’s resistant to corrosion. Another is Monel®, which consists mainly of nickel, copper, and iron. Parts made of this alloy work very well in subzero temperatures. These reasons are why the aerospace industry uses them.
Here at Special Metal Stamping we work with our clients to meet their alloy and rare alloy stampings needs. We can handle a number of rare alloys. We also have an excellent accuracy record.
