Anodised aluminium vs stainless steel: which is better?

As with many of the questions we’re asked, this one can only be answered with “It depends”. Both anodised aluminium and stainless steel have pros and cons, so it’s up to manufacturers to decide which characteristics are most important for the intended application. A few of the benefits of anodised aluminium components are that it’s lighter than stainless steel, less expensive to produce, less expensive to handle and ship, quicker to machine and able to be worked to tighter tolerances. It’s also highly conductive, in terms of electrical current and heat.

On the other hand, stainless steel is more corrosion resistant than untreated aluminium. While anodised aluminium is more corrosion resistant than non-anodised aluminium, stainless steel contains chromium and is designed specifically (as the name suggests!) to withstand oxidation. Stainless steel is also stronger than anodised aluminium, which may or may not be a concern depending on its use. Another point to acknowledge is that anodised aluminium is not suitable for prolonged contact with food, while stainless steel is perfectly suited to food preparation applications.
