Summary: H62 stands for ordinary brass belt, with an average copper content of 62%, in which H is the pinyin initials of the Chinese character "Huang" and 62 is the average copper content.

H62 stands for ordinary brass belt with an average copper content of 62%, where H is the first letter of the Chinese character "Huang" and 62 is the average copper content.

Copper alloy with other elements added on the basis of ordinary brass is called special brass, which is still represented by "H", followed by the average value of chemical symbols and other added elements. For example, H62 indicates that the copper content is 60.5% ~ 63.5%, and the balance is zinc content; HAl59-3-2 shows that its copper content is 57% ~ 60%, aluminum content is 2.5% ~ 3.5%, nickel content is 2% ~ 3%, and the rest is zinc content. There are three kinds of brass: ordinary brass, special brass and cast brass. Cast brass begins with ZCu, followed by symbols of other elements and their average content.
