We recommend two edding markers for low-corrosion labelling, which were specifically developed for nuclear, aerospace and marine applications:

• edding 8030 NLS high-tech marker (1.5-3 mm) in red or blue
• edding 8404 aerospace marker (up to 0.75 mm) in black

Should you have any other specific ink requirements, e.g. heat resistance, that are not met by either of these two markers, please contact us for assistance. It's actually highly unlikely that any of our other markers without low-corrosion properties would cause corrosion. Usually, it is atmospheric moisture or weather conditions that cause damage to metal.
