Stainless Steel Sterilization Cases


Stainless steel is a common material found in medical materials. From tools to cases, stainless steel is durable and long-lasting. However, other prominent metals circulating in the health industry are perfect for sterilization and durability. Aluminum is another popular material that has unique benefits that set it apart.

Jewel Precision is an industry leader in medical cases. With our experience, we carefully analyze the ideal metal for our sterile, functional cases. Here, we cover the differences between aluminum and stainless steel medical cases and why we choose aluminum for our products.

Steel vs. Aluminum Medical Cases


Several areas showcase the main differences between aluminum and steel. These different factors determine which metal is superior for sterilization cases.

Detailed Modules



Both materials are durable in their own right, but there are clear advantages to one or the other depending on their intended purpose. Steel is stronger considering the weight to strength ratio, but aluminum is non-corrosive and malleable, so it can be transformed without breaking. Both metals can last for long periods and resist wear from usage.

Water Resistance


Aluminum and stainless steel are both resistant to water. The chromium present in stainless steel creates a thin layer when exposed to elements like water, which prevents rust. However, stainless steel will rust after prolonged exposure to grease, moisture, chemicals or saline.

Rust is a process specific to steel, as the iron molecules bind with oxygen and begin to corrode. Aluminum is rust-proof based on its chemical makeup. Even after repeated sterilization and water treatments, aluminum will be rust-free.



Aluminum and steel work differently depending on the pH level of the substances they contact. Aluminum and steel both work well with a pH of around 7. Steel is more resistant to a pH of above 10, and aluminum is more resistant to a pH of below 4.

Aluminum is significantly lighter than steel. Steel contains high amounts of carbon, which causes it to be heavier. Aluminum is the lightweight option, which is why many other devices and equipment, such as airplanes and shelving, are made from aluminum.



Aluminum is softer than stainless steel. It is much easier to cut and mold. If you want a custom or modified design, aluminum is easier to work with and yields strong, lasting products. Steel is more likely to break or crack during the molding process, so it is better suited for less complicated designs.

If you are working at extremely high temperatures, steel is a better choice, as it will hold its form better. Aluminum begins to melt at temperatures above 1,220 degrees Fahrenheit.



Since aluminum is significantly lighter than steel, aluminum becomes cheaper overall when you consider the weight difference. When comparing the two by volume, you can purchase a larger amount of aluminum for a lower cost. This makes aluminum the more economical option for mass production and large quantities.
