What can happen when magnesium alloy exceeds its melting point?

When magnesium alloy exceeds its melting point, one of the significant risks is that it may ignite due to friction. Magnesium is a highly reactive metal, and when it is heated to its melting point or beyond, it can ignite easily, especially when fine particles or shavings are present. This ignition can occur due to the generation of heat from friction, such as during cutting or grinding operations, or even when exposed to high temperatures under certain conditions.

This characteristic necessitates special considerations during rescue operations involving vehicles with magnesium components. Personnel need to be aware of the potential fire hazards posed by magnesium alloys so that they can take appropriate safety measures during extrication efforts. Understanding this risk is crucial for ensuring the safety of rescuers and victims alike, as fires from magnesium can be extremely difficult to extinguish and can pose serious hazards in emergency situations.
