Problems solved by technology

[0004] However, the above-mentioned ordinary alloy materials that are resistant to corrosion and wear of molten zinc generally have the disadvantage of poor corrosion resistance. Although high-boron alloys have excellent resistance to corrosion and wear of molten zinc, it is easy to form reticular Fe in high-boron alloys. 2 B phase, extremely brittle, resulting in easy cracking and peeling of high boron alloys during use
