LEGOR BRASS ALLOY OTT67 / 33M (10KG BAG)

Legor OTT67 / 33M brass alloy is designed for casting brass with both vacuum machines and centrifuges.

The color of objects produced by the OTT67 / 33M has a light yellow hue.

Thanks to its particular formulation, it has a medium level of deoxidizers, resulting in a clean slag fusion and a clean crucible of residue. OTT67 / 33M offers exceptional flowability during casting and as a result parts are free from rust.

It also has a very bright color after finishing.
