How to Cast Aluminium at Home?

Casting aluminium at home is an incredible skill to master. Not only can you repurpose scrap metal around your home, but you can also create custom pieces for a variety of projects. This guide will walk you through the basics of casting aluminum so that you’ll be able to make your own creations in no time.

Gather Your Materials

The first step in casting aluminium at home is gathering all the materials you’ll need. You’ll need some sort of furnace or kiln that is capable of reaching temperatures over 1,000 degrees Celsius. You’ll also need some type of mould for your finished product, which could range from a simple sand mould to a more complex plaster mould, depending on what level of detail you want in your finished product. Finally, you’ll need some aluminum scrap metal and a crucible to hold it while it melts down.

Melting Down the Metal

Once all your materials are gathered, it’s time to start melting down the metal. Start by placing your crucible inside the furnace and setting the temperature to around 1,200 degrees Celsius. Once the furnace has reached its desired temperature, carefully place your aluminium scrap into the crucible and let it begin to melt down. This process can take anywhere from 15 minutes to an hour, depending on how large and dense your piece is. Once all the metal has melted down into liquid form, remove it carefully from the furnace with heat-resistant gloves or tongs and move on to the next step.

Pouring Into The Mould

At this point, you should have a liquid pool of molten aluminium in your crucible ready for pouring into your mould. Carefully take this molten metal and pour it into whichever type of mould you chose earlier (sand/plaster). Once all the metal has been poured into the mould, let it sit for about 10 minutes until it begins cooling off and solidifying its shape within the mould walls. After about 10 minutes have passed, carefully remove your now solidified piece from its mould and clean up any excess residue with a wire brush or other cleaning material if necessary before admiring your handiwork!


Casting aluminium at home is not as difficult as one may think—all it takes is some preparation and knowledge before getting started! With just a few simple steps outlined above—gathering materials, melting down metal, pouring into a mould—you can create amazing custom pieces with scrap metal right in your own home! So don’t wait any longer—start casting today!
