Barrels, Single Screw
XALOY bimetallic barrels provide a choice of alloys to suit your specific needs for resistance to abrasive and corrosive wear. TST extrusion Engineering is the Australasian Agent for XALOY USA, the industry benchmark, and are requested more than any other make. World-class quality from ISO 9001 registered facilities, improved structural backing steels and manufacturing techniques set XALOY barrels apart in consistency and reliability.
We offer the full product range of XALOY barrels, which include these recognised types:
X-102 sets industry standard for general-purpose bimetallic barrels. Since its introduction in 1991, X-102 provides greater resistance to corrosion and abrasive wear when compared to generic substitutes from other suppliers X-102 is a chromium-modified boron-iron alloy.
X-800 gives exceptional wear resistance. For both abrasive wear and corrosion resistance X-800 leads the industry. X-800 is a composite of particles of tungsten carbide, one of the hardest materials known, uniformly dispersed in a matrix of corrosion-resistant nickel alloy. Micro hardness testing is used to test the wear resistance of X-800 because it is a composite. Conventional Rockwell testing, involving a ball indentation device, only measures the hardness of the matrix alloy. Micro hardness testing homes in on the tungsten carbide particles that provide X-800’s exceptional resistance to abrasive wear with readings of 1200 Knoop.
X-309 gives superior corrosion resistance. For the most severe corrosion environments X-309’s nickel-boron-chrome alloy, that has less than 1% iron is the best choice. This eliminates melt contamination caused by iron-based alloys.
