Bimetallic Alloy Materials 1)Fe-based alloy 2)Ni-based alloy/Deloro alloy
3)Co-based alloy 4)NiCo-based alloy
5)Tungsten carbide/Wolfram carbide
Double-alloy level Level A - containing Tungsten of 40%
Level B - containing tungsten of 25%
Level C - containing tungsten of 9.5%

Bimetallic screw: Base material 38CrMoAlA, sprayed alloy powder on the screw flight, prolong life of screw.

Bimetallic barrel: Base material 40Cr, casted a 2-5mm wear resistant and corrosion resistant bimetallic layer

on the barrel inner wall, so it has much longer using life than nitrided barrel.


We could design for you for any Genneral plastic materials(such as PP PE ABS AS PS PC PET PA PVC PMMA TPU PU etc.)and Enginneering plastic materials(such as ABS+PC BMC LCP PPS PAR PA-6 PA-66 PA9T PA4T CPVC PVDF POM Glass fiber etc.)
