Trivalent chromate passivation, such as SurTec 650, offers strong corrosion protection while supporting compliance requirements. It also keeps electrical conductivity, which matters for grounding and EMI shielding.<\/span><\/p><h3 data-path-to-node=\"25\"><span style=\"font-size: 14pt; color: #000000;\"><b data-path-to-node=\"25\" data-index-in-node=\"0\">2.
