— lightweight, durable and reliable material, which, moreover, is practically not subject to corrosion even when in contact with "aggressive" liquids such as sour juices or alcohol. Among the disadvantages of aluminium, a rather high cost and opacity can be noted; in addition, this material conducts heat well, which is why aluminium thermoflasks (see "Type") are less effective than steel ones (however, there are not many of them).
