What removal method should not be used on magnesium alloys?

• A. Abrasive blasting
• B. Chemical removal
• C. Mechanical removal
• D. Metallic tools

Answer: (D)

Magnesium alloys pose a fire risk during removal work because fine dust and shallow heat can ignite easily. Using metallic tools can create sparks and frictional heat when they strike magnesium, which can ignite both the metal and any dust particles in the area. Because of this, metallic tools should not be used to remove coatings or corrosion from magnesium components. Safer approaches rely on tools and methods that minimize sparks and heat. Non-sparking or non-metallic tools, or alternative removal methods such as controlled chemical or mechanical techniques with appropriate precautions, are preferred. Abrasive blasting, when done with suitable media and fire precautions, and chemical or mechanical removal with care, are used instead of metallic tools.
