Why Choose Stainless Steel vs. Aluminum?

Both stainless steel and aluminum have benefits and weaknesses. Stainless steel is often chosen for applications that require corrosion resistance, heat resistance, and high strength to weight ratio. Aluminum is chosen over stainless steel when the application requires less weight. The same part made from aluminum versus stainless steel is one-third the weight. This is why aluminum is well suited for applications such as airplanes.
