Our code 4224 is an extremely fine and pure atomized powder that “wets out” easily on cast irons and steels.

  • Special gas atomized powders designed for use in all spray and fuse “puddle torches”.
  • Spherically shaped particles promote excellent powder flow through torch components.
  • Custom balanced particle sieve distribution creates the highest powder efficiency with the lowest amount of overspray.


Typical Properties
