Similarly, silver is unsuitable for body piercings. Besides being porous, silver is very corrosive and can lead to contamination. Moreover, it is also the metal that conducts the most heat, which can lead to problems with body piercings. While silver is a popular choice for surface jewellery, it is not recommended for body piercings due to its corrosive properties. It's also highly heat conductive and can cause problems if it is exposed to high temperatures. In addition, it is not suitable for small gauges.
