Barrels Nordson XALOY invented bimetallic cylinders more than 80 years ago and continues to lead the way in development of improved alloys and production processes. Nordson XALOY X-800 and X-102 barrels meet the needs for wear and corrosion resistance for more than 90% of all extrusion requirements. Strong and straight The structural shell of Nordson XALOY bimetallic barrels consists of a microalloy steel that maintains high strength and straightness after casting of the wear-resistant alloy lining. Unlike some barrel manufacturers, Nordson XALOY can produce long barrels – up to 240 in. (6.1 m) – without resorting to butt welding. The benefit to you is a stronger, straighter barrel with no seams to trap polymers that can degrade and contaminate your process. X-800: Our best extrusion barrel Composition: Tungsten carbide particles uniformly Composition: Nickel-rich iron-boron alloy. dispersed in a corrosion-resistant nickel alloy matrix. Cost-effective choice for extrusion of unfilled or lightly Outstanding resistance to both abrasive filled polymers having good thermal stability. Outlasts generic competitive barrels in Essential for extrusion of hard-to-melt materials such comparative testing. as HMW-HDPE or LLDPE and of highly filled abrasive materials such as those containing 25% or more of mineral fillers (cal-cium carbonate etc.) or glass fibers. Resists corrosive attack by aggressive volatiles released by polymers or additives. Abrasive Wear Corrosive Wear Test conditions: The German Plastics Institute, Darmstadt Germany, used standard molding equipment to inject 10 kg of nylon and polycarbonate materials containing 30 and 50% glass fibers through a 0.5 mm Ø orifice in test specimens made of the barrel alloys.
