However, chromium is more expensive than zinc, and it is not as effective at preventing corrosion. Lead and antimony are not typically used to galvanize iron, as they are not as resistant to corrosion as zinc or chromium.<\/p>\n<p>In conclusion, the metal used to galvanize iron to protect it from rusting is zinc.
