As per subject, what material are the gas burners on the hob made of?

SWMBO has burnt something onto one and wants me to clean it off. I'd
usually start with a soak in Soda Crystals but that's a no-no for
aluminium. It feels light and is non-magnetic.

It's a Russell Hobbs and the only help in the manual is to use a metal
surface cleaner - suggestions?

Our gas hob (now replaced with an easy to wipe clean induction hob, as
my wife is disabled and has very weak wrists and finger joints) had
"chromed" aluminium burners and enamelled cast-iron caps. We didn't
bother about maintaining the finish and just shoved them in the
dishwasher - but it does strip the chroming.

The burner bits that you are describing are made of some sort of
aluminium based "pot metal" (mine are not chromed). I'd be surprised if
even concentrated washing soda attacked them at a significant rate (but
you could always try one and keep an eye on it for signs of reaction).

If its not plated, simple abrasion is a good way to simply remove the
waste material and then slightly abrade 'what lies beneath' - finish off
with fine wet and dry to restore surface sheen...

They feel like aluminium but I was surprised that was a material that
would be used for flame. Just the one that has something burnt on it.

The usual method is to use XRF to identify the metal/alloy.....

I'd not expect it to be ally, more like stainless steel or chromed ferrous
metal, try a magnet on them to see if its an alloy or not.

The burner will not get that hot, there is a continuous flow of gas and
air mix passing through it.

Several Niton XL2s, but none under £10k. I've used much earlier
versions, IIRC they were about £5k in the 1970s.

you have to look for x-ray fluorescence spectrometer and the three main
suppliers of this equipment are

Fischer scientific
Niton Uk
Oxford Instruments

They are not the sort of thing you will find on Ebay.

Alternatively you could buy a SEM with an EDS or WDS spectrometer
attached but that means destructively cutting your object to give you a
small sample to put into the vacuum chamber.

Well, not for cheap anyway
