Sialon hot dip galvanizing hooks


Strong Sialon II ™ (or silicon nitride like) hot dip galvanizing hooks are typically used in the non-ferrous industry during aluminium galvanizing

This method modifies the surface properties of e.g. aluminum and steel. 


This technique is generally applied to piston rings.


With regards to Sialon ceramics, there is substitution of silicon by aluminum with corresponding atomic replacement of nitrogen by oxygen, to satisfy valency requirements. The resulting 'solution' has superior properties to the original pure solvent, syalon, silicon nitride or Si3N4.

 

Silicon Nitride like ceramics (like ceramic hooks) have found extensive use in non-ferrous molten metal handling, particularly aluminum and its alloys, including metal feed tubes for aluminum die casting, burner and immersion heater tubes, injector and degassing for nonferrous metals, thermocouple protection tubes, crucibles and ladles.

Features:

  • Improved corrosion and wear resistant properties.
  • High density and high strength assure reliable and stable operation.
  • High thermal shock resistance allows repeated insertion and withdrawal from molten metals.
  • 12 months warranty against chemical attack

 

Typical application:

  • Modification of metal properties (piston rings
