PMET 50

IRON ALUMINUM THERMAL SPRAY WIRE

Characteristics and Composition

PMET 50 (Fe-Al) is an iron aluminum cored wire specifically designed for arc spray systems. It produces a well bonded coating with high hardness. It has the unique ability to produce either smooth or very rough profile coatings for non-slip applications. PMET 50 coatings have excellent machinability. Typical applications include non-slip coatings for walkways and stairs, gripping rolls and bond coats.
