Aluminium vs Stainless Steel

A few people have recently asked me what is the difference between aluminium and stainless steel (when it comes to water bottles). Good question and one I thought I would add to my blog especially after seeing cheap BPA-free aluminium bottles in the supermarket today.

So what's the difference?

• Most stainless steel bottles are made from Premium 304 food grade stainless steel and should have BPA-free attachments ie the lids.
• Chemicals will not leak from the stainless steel or the BPA-free attachments into your drinking water.
• Stainless steel bottles are stronger and will last longer than aluminium.
• Bottles made from aluminium are usually lined with plastic and therefore may still leach chemicals into your water. These bottles are often cheaper however they are not really helping you health wise. Studies are being done on the effects of chemicals leached from aluminium including the risk of Alzheimer’s disease.

What to look for when buying a new bottle:

• When looking for a new bottle you should look for one that is 304 food grade stainless steel and that is clearly marked BPA-free.

Many supermarkets and large variety stores are now stocking water bottles labelling them BPA free and they are quite cheap. But be careful - many of these are aluminium or are made from cheap stainless steel.
