Copper Alloy for Burner

Copper Alloy for Burner

Copper Alloy for Burner

(OP)
Hello I am designing a burner for a packpack stove, the burner needs a hi thermal conductivity, good corrosion resistance, as light weight as possible.
Most you see are made of some type of Copper Alloy. Which one would you recommend? I would love to use Aluminum because of the weight, but I believe its melting point is far to low.
I am going to machine the prototypes but because of its use, free machining (leaded) materials cant be used.
Im not a materials engineer, just mechanical, so any help would be appreciated.
If i had to guess I think most are made of some type of brass, yellow colored, not red.

RE: Copper Alloy for Burner

Are you talking about the nozzle itself?
If so then look at pure Cu, or perhaps a Cr copper alloy.
Thermal conductivity is more important than anything else.
And make sure that what it connects to will dissipate the heat, that is how they survive.

here is a link to one of the products, as you can see the burner bell (so its called)is made of some type of brass, i dont know which kind would be best used. i would assume the cheapest for production 360 brass?, thats what we machine parts from here most of the time, but 360 has a small amount of lead in it. Does that matter for the situation.
The flames heat the bell to glowing orange, and the incoming liquid fuel pre-atomizes upon entrance at the bottom, before the nozzle due to the hi thermal conductivity of the material, aluminum would melt, i believe, i would love to use titanium, but poor thermal, and pricy.Everyone used some type of what looks to me to be brass?
