What is bi-metal

• Bimetallic means two metals
• Nitrated is one metal
• Strong metal outside for the screw
• Strong metal inside for the barrel

3
Bimetallic Cylinders

• Cross section of a bimetallic barrel
• The dark inner ring is the strong bimetallic
  alloy
• Depending on the application, different alloys
  are recommended

4
Bimetallic Screws

• The finished screw has 3/10 to 5/10 mm left on
  each side
• Depending on the hardfacing the welding method is
  different
• After welding the edges are finished to
  specifications

5
Benefits

• Longer protection
• Stable protection
• calculable risk
• anticipatory maintenance

6
Xaloy - Added Value
