introduction to magnesium alloys high melting point
Briefing: Safe Magnesium « Galaxy Trade and Technology
Solid magnesium parts will not burn until heated above the melting point. This melting point is similar to aluminum, at 650 ̊C or 1202 ̊F. If locally melted, the high thermal conductivity of magnesium will generally ensure rapid cooling and prevent a fire from spreading.
