What material is a cooker burner made from

[rogersimms]

Hi All

Can anyone tell me what material a cooker burner is made from. As I can not identify the actual cooker I need to turn some burners. I have tried aluminium but this material will warp and get mishappen when hot.

Any ideas will be a great help Thanks

As they tend to rust if neglected I would guess that they are cast iron?

Yep, cast, but mild steel will do but like the ally may not be stable, Should be able to get hold of a bit of cast iron bar, that will turn, or make a pattern and get a friendly caster to put it in the corner of the mould box. Or just buy a cheap one off ebay for spares
Post a picture of the oven, there may be an oven nerd on here

Didnt think of cast iron and didnt know you could get a bar for turning. I thought it would be made from some sort of alloy as the new ones all seem to weigh very little and are shiny either a brass color or aluminium colour.

I think my burners (Eno stove) are ally and one has warped and had to be replaced!

The ' covering' over the top (ie the disc over the part with the slots) probably is cast iron.

This post reminded me of an experience that I thought I should share, hence this thread: http://www.ybw.com/forums/showthread.php?p=3513223#post3513223

May or may not be relevant.

My boat cooker has cast iron burner caps and my home cooker has brass burner rings.
I have also seen brass burner caps on some boat cookers in the past and these have usually been located on top of alloy burner seats, when the holes become blocked the flame becomes uneven and this causes the alloy seat to distort which in turn makes the flame picture even worse,
so always keep the holes clean.

On the boat some sort of steel as they rust. At home a cast 'iron?' cap with some sort of alloy ring below.

I would guess that most of the burners are cast iron, but would imagine that machining a new one would be easiest in brass. Apart from copying the burners accurately, take a good close look at the underside, though. On the Plastimo (and others) models, there are shallow ridges to hold the burner off the seat a little. The gap produced is for secondary aeration of the mix - when they get blocked with fat and grease from washing the tray, the flame burns yellow and tends to "stand off", not burning until a few mm from the burner. I spoke with the manufacturers a while back and they told me that some people in mid ocean had put strands of wire under the burner to maintain the gap until they could get replacement parts.

Thanks guys for all the posts.Will have a look at what materials I can get hold of.

Cooker burner

I presume you want the round steel cap type of diffuser with lots of holes around the perimeter for the gas to come out and burn in a circle. The gas or kerosene or meths will come out as a vapour through a jet to mix in air it is then diffused to make a usable ring.
I would imagine that any suitable sized diffuser would be OK provided it fitted. Look for old gas stoves or camping cookers. They all work the same. I wouldn't think it would be necessary to make one. olewill
