Specialized Anti-Corrosion Bolts for Magnesium Alloys
Magnesium is the lightest structural metal but also the most anodic, so when it is joined to steel or other dissimilar metals a large electrode-potential difference drives aggressive galvanic (bimetallic) corrosion — especially in wet, condensing or road-splash conditions. Toprecision anti-corrosion bolts for magnesium alloys solve this at the source with a specialized dielectric coating applied to the fastener.
The coating isolates the bolt electrically from the magnesium substrate, stopping the galvanic cell that would otherwise eat away the parent material around the hole. The result is a multi-material joint that keeps its clamp load and structural integrity over time instead of corroding and loosening. By enabling magnesium to be paired safely with stronger metals, these bolts support aggressive lightweighting without sacrificing durability or safety in the field.
By stopping corrosion at the coating, the bolt lets engineers pair magnesium with stronger metals and still meet lifetime durability targets on the joint.
The definitive choice for lightweight, high-reliability joints, these bolts serve automotive chassis and powertrain housings where weight reduction is critical, NEV battery packs with magnesium enclosures, aerospace magnesium-framed structures, and precision electronics with sensitive magnesium cast housings. They are optimized for magnesium die-castings that must integrate securely with other metals.
From chassis and powertrain to NEV packs, airframes and electronics, it unlocks magnesium lightweighting without corrosion-driven recalls.
