87-Hour Corrosion Test: Magnesium + Tagnite vs Black Nitride Steel

We ran an 87-hour accelerated corrosion test comparing a ROAM Rifles magnesium upper receiver finished with Tagnite® + Cerakote® against a black nitride steel bolt carrier group. Both parts were exposed to a harsh solution of salt, hydrogen peroxide, and vinegar to simulate extreme corrosion conditions far beyond normal use. Results: The magnesium upper showed significantly less corrosion, proving that with proper surface treatment and basic care, magnesium components will not fail first—and can outlast many traditional steel parts. This test highlights why material selection and protective coatings matter more than base metal alone.
