Extrusion barrel X-800

Since 1973, Xaloy® X-800 bimetallic barrels have proven that they far outlast nitrided barrels in processing rigid PVC, other vinyl materials and plastic-wood composites. Xaloy® X-800 barrels are lined with a composite consisting of superhard tungsten carbide particles uniformly dispersed in a nickel alloy matrix. Screw compatibility Screw-barrel compatibility is especially critical in counter-rotating twin-screw extrusion because of very high screw-to-barrel loading and the potential for adhesive and abrasive wear at the interface. Xaloy® 830 screw surfacing is the ideal companion to X-800 barrels. It too is a hard, durable tungsten carbide composite specially formulated for maximum compatibility with X-800 barrels. We work closely with leading extruder manufacturers and processors on testing various screw coatings to insure compatibility between our barrels and their screws.
