Since the introduction of Alconite Ring Concept Guides, rod builders and anglers alike have been amazed at their performance characteristics. When combined with the lightweight New Guide Concept frame the results are unparalleled.... 35% lighter and up to 50% stronger than ordinary guides. These Alconite Concept Guides incorporate Fuji’s Corrosion Resistant S-4 Stainless Steel for easier maintenance. Fuji’s Engineers thought long and hard on how to make a guide lighter and stronger yet keep the cost down. After years of research they came up with Alconite, a special type of ceramic that offers strength, lightness, and durability. In fact Alconite offers 80% greater compression strength and is 20% lighter than aluminum oxide. Also through Fuji’s Diamond Polishing, Alconite boasts a finish that is smoother than that of Hardloy®. Fuji engineers were also able to make Alconite the thinnest and lightest ceramic ring available today; even 7% lighter than standard SiC Rings! Alconite is one more reason why Fuji is the undisputed leader in rod components.
