Example Embodiment
[0019] In the following, the two embodiments of the present invention are compared with the conventional products on the market, HSn70-1A (i.e. Comparative Example 1) and HSn70-1B (i.e. Comparative Example 2). The composition of each component of the two comparative examples (see Table 1) and the difference The comparison list of corrosion resistance performance indicators in corrosive media is as follows (see Table 2) to further illustrate the excellent performance of the present invention.
[0020] Table 1 Chemical composition of Examples and Comparative Examples
[0021] Chemical composition (wt%)
[0022] Table 2 Static corrosion rate (mm / a) of Examples and Comparative Examples in different media
[0023] NaCl(3.5%)
[0024] It can be seen from Table 2 that the corrosion resistance of the rare earth tin-containing brass prepared in Examples 1 and 2 is better than that of the ordinary arsenic-tin-containing brass HSn70-1A and HSn70-1B.
