The quality of the water bottle plays a big role in the service life of the water bottle and the quality of drinking water. Although each material has its own advantages and disadvantages, stainless steel bottles are still the most popular choice for quality and flexibility. Compared to glass or BPA-free plastic, you can rely on stainless steel water bottles for extremely high durability. But what about aluminum bottles? Let us take a look.

 

 

Features of stainless steel water bottle and aluminum bottle

It is a bit difficult to distinguish between aluminum bottles and insulated water bottles because they look and feel slightly similar. However, the advantages of using stainless steel bottles will undoubtedly exceed the advantages of using aluminum bottles. The following are the main differences between stainless steel bottles and aluminum bottles:

Durability

The stainless steel vacuum flask is made of double-layer stainless steel inside and outside. The inner tank and the outer shell are combined by welding technology, and the air in the interlayer between the inner tank and the outer shell is drawn out by vacuum technology to achieve the effect of vacuum insulation.

 

The dents of aluminum bottles are much easier than stainless steel. Despite the similar appearance, stainless steel bottles are more durable than aluminum bottles.

 

Safety

Stainless steel is corrosion-resistant, wear-resistant, safe and hygienic. It is very suitable for homes, hotels, offices, etc., and its metal strength is high, suitable for different surface treatment processes, and its appearance is simple and beautiful. Moreover, the vacuum technology is adopted in the current vacuum flask, which makes it have better performance of delaying the thermal conductivity of metal than the aluminum kettle, and the heat preservation time can be as long as 12 hours.

 

The aluminum material is tough, light, and malleable. It is very suitable for making a kettle for people's daily travel. Aluminum has high surface adhesion and is suitable for printing various colors and patterns, which is more in line with human pursuit of beauty and modern people’s needs for individual expression. However, recent studies by scientists have found that aluminum damages the human brain, heart, liver, kidney and other functions and immunity. Moreover, in 1989, the World Health Organization also officially identified aluminum as food pollution and controlled it.

What is the main difference between stainless steel and aluminum

Aluminum is reactive, which means it can react with certain liquids. Aluminum bottles usually have some kind of lining as a barrier between the bottle and its contents. Enamel, resin, or other materials that may contain plastics (or chemicals) are often used to construct linings. Stainless steel is non-reactive, so you don't have to worry about certain liquids interfering with the integrity of your bottle or drinking water.

 

In the past, aluminum water bottles have always been the mainstream products for outdoor sports, and they have the advantages of being portable and strong in impact resistance. But now, with the progress of the times and the development of technology, aluminum kettles have been replaced by stainless steel insulated water cups made of high-quality food-grade 304 stainless steel.

 

Finally, in order to allow everyone to drink healthily, topdrinkware here recommends that when you buy vacuum insulated water bottle, it is best to go to regular shopping malls and supermarkets to choose some well-known brands of best stainless steel water bottle, or log in to our official website to buy suitable products.
