The material of the sports bottle is pure aluminum. As a big country of aluminum products, China has a complete range of products. In terms of material selection, each manufacturer has its own characteristics. Many domestic kettle brands use pure aluminum with a purity of 99.5%, but the actual situation is not the case. Even most manufacturers use recycled aluminum.
Another factor is the wall thickness of the kettle, which is generally 0.7 mm thick. Since it is difficult for the average consumer to distinguish the wall thickness of the sports bottle, some manufacturers will opportunistically reduce the wall thickness of the kettle to save materials in order to reduce the cost. Some manufacturers even reduce the wall thickness to 0.5 mm. An intuitive feeling of judging the thickness of the kettle wall is that if the contrast is in the hand, the weight of the kettle that is thinner will be lighter.
If the sports bottle is made of aluminum with low purity, or the wall thickness is reduced, it is easy to sag, smash or even burst due to collision or falling. Generally, the higher the purity of the aluminum sports bottle, the higher the wall thickness, the better the strength and toughness of the sports bottle, and the stronger the ability to resist collision and impact. Of course, the better the quality, the higher the cost and price.
