运动水壶的材质

塑料，不锈钢，铝制的都有。
塑料的优点：轻便，导热慢装热水不烫，大口，价格便宜。缺点：不耐磨，材质不合格会有有害物质。
不锈钢优点：坚固，无有害物质对人无害，耐热。缺点：单层的导热快不耐磨，双层的不锈钢容器对加工精度要求较高，接缝处容易漏水和滋生细菌。
铝制品优点：轻便，外观时尚。缺点：导热太快，装热水没法拿，装冷水也没法拿。铝制品太软容易磕碰出凹坑，铝摄入量过多会对人体造成伤害。

陶瓷：19世纪以前最流行的材质。
玻璃：19世纪以前贵族用的水壶。
铝：
（1）被LAKEN认为是最高贵的材料，他们不断的对其进行调查研究，同时我们也致力于最新一代的塑料的研究探索，所研究的材料被广泛应用于制造运动水壶，餐具和附有精美图案的高品质容器，这些使得LAKEN成为世界著名品牌。
（2）铝在1980年代被认定为对人体摄入有毒，铝壶必须要有安全卫士的内涂层，并且不含BPA。
塑料：塑料的特性决定了不能长期频繁做喝水用途。
不锈钢：目前还没发现有毒释出，所以不需要加内涂层，但缺点也很明显：重，瓶身结合缝易藏菌和诟。

铝制水壶朔源：
Spanish designer Gregorio Montesinos became aware of the manufac-turing potential of aluminium, then a new metal, when he was working in France in the emerging aluminium industry. The modern aluminium industry was effectively born in 1886 when two unknown young scientists, Paul Louis Toussaint Heroult, from France, and the American, Charles Martin Hall, simultaneously invented a new electrolytic process, the Hall-Heroult process, when they discoverred that if they dissolved aluminium oxide in a bath of molten cryolite and passed a powerful electric current through it, then molten aluminium would be deposited at the bottom of the bath. This is the basis for all aluminium production today. Returning to Spain, Montesinos established his own company in Murcia, and began to design water bottles as a cheap and lighter alternative to the ceramic and glass drinking bottels available at the time. Aluminium is strong and lightweight, and remarkbale for its resistance to oxidation, properties that Montesinos was keen to harness. Designing for the armed forces and with mass production in mind, he came up with the Clasica. Made from 99.7 percent pure isotope aluminium, it is anticorrosive and hygienic, as well as extremely light and durable...
西班牙设计师格雷戈里奥·蒙特西诺斯（Gregorio Montesinos）在法国从事新兴铝材工业的时候，他意识到铝作为一种新的材料的强大潜能。现代铝材工业诞生于1886年，通过电解熔融氧化铝冰晶石，沉淀制铝，这种工艺一直沿用到现在。回到西班牙后，格雷戈里奥就在穆尔西亚（Murcia）建立了他的公司，开始设计制造铝制水壶，以其轻便和廉价取代陶瓷和玻璃水瓶。铝材质地坚韧而轻，有延展性，其特点被格雷戈里奥发挥到极致，由此成就了水壶的经典设计——“Clasica”水壶由99.7%的纯铝制成，防腐卫生，极轻耐寒，坚固耐用。水壶的外壳用织物或者皮革包裹，防水保温，而且保护水壶。
