If your hobby or job involves metal fabrication, you likely know that alloys can be a great way to enhance metal properties. Exotic alloys—that is, metals with an unusually high alloy content—have a number of different applications. Since they’re extremely durable and resistant to corrosion, deformities and oxidation, they are especially good for making metal springs.
When you work in extreme conditions, exotic alloys are a smart option. They can stand up to much higher temperatures than pure metals or those with lower alloy content. Here are some of the most popular exotic alloys for metal springs, and suggested industrial exotic alloy applications.
Exotic alloy springs
When you choose an exotic alloy for a spring, it’s important that you understand how that specific alloy will serve your needs. For example, if your project is going to be used in the ocean, you’ll need an alloy that can stand up to intense water pressure as well as saltwater. If you’re working with high temperatures, you need an alloy that won’t distort or deform in the heat—which is why stainless steel is a bad choice for that particular use.
- Nickel-cobalt alloys: If your fabricated springs will be used underwater, consider using a nickel-cobalt alloy. One type, MP35N, is especially resistant to saltwater corrosion, hydrogen sulfide and mineral acids. Alternatively, you could try Monel, which is excellent for acidic applications as well as marine usage. It is a nickel-based alloy, combining copper and iron to achieve these effects. The specific alloy you choose will depend on exactly what you need from your fabricated parts—make sure to research the best alloy for the job.
- Titanium alloys: Titanium alloy springs are often found in high-performance vehicles, especially those that are used in racing and off-roading. On the other end of the spectrum, nickel-titanium alloys are used in orthodontic applications—springs made with this exotic alloy are incredibly elastic, which aids in this specific use. Titanium alloys can be created to withstand high pressure and high temperatures (suitable for nuclear applications and offshore drilling), while remaining strong and corrosion resistant.
How to choose the right exotic alloy
If you’re not sure which alloy would work best for your project, even after doing the research, your next step should be talking to metal fabricators. Metallurgists will understand how to get the results you want from the exotic alloys available.
You might be surprised at exotic alloy applications—for example, platinum alloys are a popular choice for fine jewelry, thanks to their brilliantly shiny nature and super durability. No matter what the size and scope of your project, there’s a good alloy choice available. They take the best characteristics of each metal type, and combine them to create a durable, corrosion-resistant and strong material.
