Aluminum vs. Stainless Steel: Which One is Right for You?
Share
It’s almost impossible to go through your day without encountering stainless steel or aluminum. From the car you drive to the kitchen sink, these metals are everywhere. Though they might look similar, stainless steel and aluminum each have unique properties that set them apart.
5 Key Differences Between Aluminum and Stainless Steel
Before starting your next project, it's essential to understand the differences between stainless steel and aluminum. Here are five critical factors to consider:
1. Strength
While both stainless steel and aluminum are strong, stainless steel generally outperforms aluminum in terms of raw strength. However, aluminum’s lightweight nature gives it a higher strength-to-weight ratio, making it ideal for applications where both strength and lightness are crucial.
2. Weight
Aluminum’s lightweight properties make it a popular choice for use in airplanes and skyscrapers. Many of the world’s tallest buildings are constructed using aluminum alloys, which are strong enough to support the weight of heavy glass panes while keeping the structure light.
3. Cost
Generally, aluminum is less expensive than stainless steel. However, both materials are competitively priced and are highly recyclable, making them cost-effective and environmentally friendly options.
4. Corrosion Resistance
Both materials offer corrosion resistance, but stainless steel has an advantage due to its chromium content. The chromium in stainless steel forms a protective, invisible shield that guards against corrosion. If the stainless steel does rust, this layer bears the brunt, and it renews itself after the rust is removed.
Aluminum doesn’t rust like steel but can corrode. It has its own protective layer, a thin film of aluminum oxide, which shields it from rust but may not prevent other types of corrosion.
5. Conductivity
When it comes to thermal and electrical conductivity, aluminum outperforms stainless steel. This makes aluminum the material of choice for applications like cars, air conditioning units, and high-voltage power lines.
