MAGNI 550
Fastener Coatings

Product Description

Magni 550 is a duplex fastener coating system that combines an electroplated zinc and chromate substrate with an aluminum-rich organic topcoat. The electroplated zinc layer provides sacrificial protection of the steel substrate while the topcoat creates a durable barrier. Magni 550 is engineered with integrated friction modifiers to eliminate the need for sealers or post coating lubricants. This feature ensures repeatable torque/tension characteristics in assembly. Magni 550 provides superior product performance in fewer layers than comparable finishes. Fewer processing steps results in improved quality and reduced costs. Magni 550 is designed for use on fasteners such as nuts, bolts, and other miscellaneous hardware.

Magni 550 can be applied via dip/spin, dip/drain, or spray application methods.
