Hello everyone, I’m testing a new material in wet shave world , magnesium it’s a very light material, but as many know the problem is corrosion. It’s getting with some black spots and at the same time looking opaque. I'm really liking the look…

Aluminium? Maybe.
Titanium? Definitely.

But I never would have thought of magnesium as a material for shaving brushes.
Maybe that is because (despite being trained as an aeronautical engineer and having worked for many years as an airline pilot) I still associate magnesium with chemistry classes and its violent reactions to water.

I also noticed that is seems to tarnish badly.
If not steel, my money would be on titanium, but that is notoriously difficult to work with and is probably not practical for a DIY project,

Keep it away from naked flames!

I found this:

Is magnesium flammable or explosive?
highly flammable
Magnesium metal and its alloys are explosive hazards; they are highly flammable in their pure form when molten or in powder or in ribbon form. Burning or molten magnesium metal reacts violently with water.

Be that as it may, magnesium alloys are frequently used in aerospace and other applications where the weight advantage is just too tempting.

They are usually magnesium alloy castings, often for gearboxes or transmissions.

Here is a somewhat dated (just like me ) presentation from the 2007 triennial Aircraft Fire and Cabin Safety Research conference: https://www.fire.tc.faa.gov/2007Confere ... umPres.pdf

Mg + H2O = MgO + H2. I doubt that there is really any danger of combustion. My hot water tank has a magnesium rod as a sacrificial anode to protect the copper. A shaving brush is a far cry from a flashbulb.

Thank you so much for all your comments and opinions. The magnesium shaving brush is now being tested in a pass around and so far so good, everyone is loving it

Thank you so much

I like the look of the stainless steel - copper brushes.
