Hazards when working with magnesium parts - AS60.00-Z-0005-01N

Model 215 

MODEL 215 

General: 

Magnesium has the property of forming a compound with oxygen extremely quickly. Nevertheless, it is resistant to air because it is coated with a dense, unbroken thin oxide skin which protects the metal underneath from further oxidation. If magnesium is ignited in air, it burns at approx. >500 °C with dazzling white light and severe heat development (approx. 2400 °C).

Like aluminum dust, magnesium dust is also combustible, as well as explosive when mixed with oxygen.

For further information see the accident prevention regulations or the trade association regulations.

Machining/treating magnesium: 

• Processing magnesium components  with an open flame (welding, cutting, soldering, heating, etc.) and grinding that creates sparks are prohibited  .
• In the event of structural damage to the driver doors, these must be replaced completely.

Corrosion protection: 

• Incorrect coatings, areas affected by corrosion and surface repairs must not be repaired for reasons of corrosion.
• To prevent contact corrosion at the threaded connections on the inner door parts, coat contact surfaces and screw shanks with paint after removal or replace screws/bolts.

Do not use zinc dust paint!

• Plastic bushings and disks installed as standard must not be removed and damaged parts must be replaced.
• Due to extremely severe contact corrosion, damaged threads in the magnesium pressure castings may only be repaired with the MB-approved Helicoil thread inserts made of aluminum.
