Sialon Galvanizing Hooks

Silicon Nitride 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.

Description

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.
