Sialon 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.

Description

With regards to Sialon ceramics, galvanizing hooks, being part of that group, 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 galvanizing 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.
