40% Greater Chromium Content Is Key to Enhanced Corrosion Resistance of Nordson XALOY’s X220™ Inlay for Extrusion and Injection Components

NEW CASTLE, PA, U.S.A., -- A new bimetallic barrel alloy developed by Nordson XALOY exhibits greater corrosion resistance than comparable general-purpose iron-based inlays currently standard in Europe, providing a longer working life, increased productivity, and enhanced process consistency and product quality, the company announced today. Nordson XALOY will introduce the technology at K 2013 (Hall 11, Stand A26).

The X220™ inlay for extrusion and injection molding barrels is an alloy of iron, boron, and chromium, with a chromium content more than double that of the X200™ alloy already available from Nordson XALOY and 40% greater than a standard alloy widely used in Europe. In acid immersion tests by Nordson XALOY, the new X220 alloy exhibited a 46% improvement over the European standard material in terms of sample weight loss in sulfuric acid, and a 31% improvement with hydrochloric acid.

In both acid tests, the X220 alloy outperformed X200, an iron-boron-chromium alloy already available from Nordson XALOY, and in all corrosion tests the X220 outperformed the European standard material.

“The superior corrosion resistances of Nordson XALOY’s X220 alloy enhances throughput and reduces downtime for extrusion processors and enables molders to achieve consistent, on-specification production,” said David Hotchkiss, global product manager. “As a new entry in the world’s broadest range of single- and twin-barrel products, it extends our ability to meet the full spectrum of processor needs.”
