Magnesium Honeycomb section in auto exhaust in Australia
Does anyone know of which model falcon or commodore had this section in it? Baring that does anyone know of a reliable magnesium source in Australia,
can be an alloy its just for burning for a demonstration.
Actually that reminds me, Prince made a tennis racquet out of magnesium in the eighties, the 'Prince Magnesium Pro'.

The head of some power-tools (a jigsaw I think I saw in Bunnings) is advertised as 'magnesium' - prob an alloy with aluminium

In the UK metal pencil sharpeners are made from magnesium.
Placing one of them on the corner of a tripod and heating it with a Bunsen burner will result in it catching fire, a favourite trick of naughty
students in school chemistry.
Apart from that you could try a camping shop for a fire lighter.
I think some hard disc cases are made from magenesium so if you have an old crashed one that may be of use.
NeXt Cube computer cases are made of magnesium and yes you can burn a whole one!

If you search for replacement sacrificial anodes for hot water heaters, you'll probably find someone who will be happy to send you some offcuts, which
are magnesium around a small (ca. 3 mm diameter) iron (I think) core. Yo can then shave the Mg off, drill out the iron, or whatever you want to do
with it.
In this way, I once got near 3 kg of magnesium for the cost of a self-addressed post satchel.

I bought a block fire starter from an army surplus and camping store which is solid Mg 9x25x80 mm. Got it for under $10, can't remember the exact
price.

Which was a long time ago? The free-for-postage Mg cutoffs? Or the other stuff, in general?

Why not just buy the pure stuff off ebay?

More likely its called magnesium because its a similar colour to magnesium. I think there should be a moratorium on any new product names utilizing
the word 'titanium'.
Thanks for the firestarter tip, guess i'll go with that, if you want reliable, source it from the military (except the pakistan military).

Hi Panache,
It might be worth finding an old hardrive body,i think the top cover
stainless and the rest is clean magnesium.

If this is the case, you ought to be able to get megnesium pretty easily from computers in thrift stores, and sometimes in old surplus school supplies
-- though they take out the hard drive.. you'd have to ask them before they toss them. Probably get it for free if you were lucky.

I can't say I have checked this out personally, but can't you just go into a boat shop and get a magnesium sacrificial anode.
Aluminium boats always use magnesium anodes, but zinc and aluminium are available as well.
They come in all sorts of weird shapes and sizes. Just get a simple block shape, they are cheapest. There is a whole range listed on e-bay as well.

Go to a concrete workers' supply house and see what the big flat tools that go on the end of a long pole are made of. Here they are called a 'bull
float', and are magnesium. They also sell a tool for spreading stucco or plaster on walls called a 'Darby' , also magnesium or an alloy of magnesium.
I got a bent one from a worker who stepped on it.

So i went into a concrete/concreters trade store, to my dismay it was empty and the three dinky-di aussie dudes working there immediately asked me
'yup anything you need help with', unfortunately all their heads imploded immediately the word magnesium was used so i could not get anything further
from them, but apparently we do not have anything like that.
