How to Melt Magnesium – A Complete Guide

How to Melt Magnesium

Magnesium is a lightweight, strong, and cost-effective metal that can be used in various applications. It’s often used in engineering projects such as cars, boats, and aircraft and industrial-grade applications such as medical equipment. To use magnesium effectively, however, it must first be melted down into a molten state. If you’re looking for an easy way to melt magnesium safely and quickly, look no further – this guide will provide the step-by-step instructions you need!

Safety First!

The first step when melting any metal is safety. This process requires high temperatures and open flames, which can be dangerous if not handled correctly. Ensure you wear all the necessary protective gear – safety glasses, gloves, long sleeves/pants, etc. Additionally, ensure your workspace is well-ventilated to prevent fumes from accumulating.

Melting the Magnesium

Once your workspace is prepped for safety, you’ll need to prepare the magnesium for melting. Start by chopping the magnesium into small pieces or shavings 1/8 inch thick or less. This will help facilitate faster melting times later on. Once your pieces are prepared, add them to a crucible (a heat-resistant container made of ceramic or graphite). Place the crucible onto a flame burner and turn up the heat until it reaches around 2200°F (1200°C). At this point, your magnesium should begin to melt into a liquid form – if it isn’t melting at this temperature, then increase the heat slightly until you reach desired results. When melting magnesium, it’s important not to exceed 2500°F (1371°C) as this could cause oxidation of the metal, reducing its quality significantly.

Pouring & Cooling

Once your magnesium has reached its molten state, you can pour it into molds or other forms containing molten metals. At the same time, they cool off and solidify back into their original condition. Afterwards, allow plenty of cooling before removing your newly casted piece from its mold!


Working with molten metals like magnesium requires special care and attention to ensure safe handling and optimal results every time! By following these simple steps, you should have no trouble melting down magnesium quickly and safely, so you can use it in whatever application you desire! With correct safety precautions and proper tools on hand, nothing stops you from doing amazing projects with molten metals! Good luck!
