Stainless steel also serves as an excellent alternative to aluminum due to its strength, fatigue properties, and ability to withstand high temperatures. It is especially recommended over aluminum if the application depends on material strength and/or the material’s ability to withstand harsh environmental conditions. Ferritic stainless steel can be more than 10 times stronger than aluminum, while austenitic stainless steel can be five times stronger. Stainless steel surfaces can be passivated for improved corrosion resistance if necessary and can handle conditions of up to 700°C. Aluminum components are only optimal in low-temperature applications of less than 300°C.
For these reasons, we often recommend stainless steel as a reliable alternative to aluminum. If material weight is an important factor in the success of your application, titanium may serve as a better option.
