Electrical JointingAlminox ALM / H2397 Electrical Jointing Compound
Short Description
Alminox ALM / H2397 Electrical Jointing Compound is a conductive compound for aluminium electrical connections.
The same Alminox product is referenced as ALM by Preformed Line Products (PLP) and H2397 by TE Connectivity / Utilux.
It contains conductive zinc particles suspended in a grease base. Under compression, the particles help penetrate aluminium oxide film, while the compound seals the joint against air and moisture.
Recommended for aluminium-to-aluminium bolted and compression connections.
