Oil feed fitting that threads into turbo

[Rocketmn]

I have to buy a 1/4" mpt inverted flare 90 fitting to screw into my turbo. All I can find are brass and maybe aluminum. Would the heat from the turbo housing itself affect (melt) either of these metals? I'd like to get a steel or ss, but I can't find one.???

Nevermind...I should of found out the melting temps before I made this post...
