Doing hot stuff again 🔥
This time it's a mixture of copper, aluminium and manganese called a Heusler alloy, named after its discoverer.
It's made from non-ferromagnetic metals but is ferromagnetic when combined!
The first time I tried it in my furnace and the mixture did not flow together properly. But it is magnetic!
So I tried the same powder mixture again but this time in a furnace that can reach 1400°C instead of only 1100°C.
And just for fun I tried to remelt the first attempt.
