[QUOTE="jim hardy, post: 4979221, member: 327872"] I was thinking of Monel for your heating wire not the plates alloy 400 looks at first glance to have coefficient of expansion very close to aluminum's and good chloride resistance and it comes in wire [URL]http://www.dragonalloy.com/CuNi_Alloys_213.html[/URL] Coefficient of thermal expansion @20-100C ( x10-6 K-1 ) 13.9-14.1 im having difficulty locating chloride resistance of 80-20 Nichrome here's a tech brief that might have some search terms for a long winter nigh t[PLAIN]http://materion.com/~/media/Files/PDFs/Alloy/Tech%20Briefs/AT0024-0311%20-%20Tech%20Briefs%20-%20Chloride%20Stress%20Corrosion%20Cracking%20Resistance.pdf[/PLAIN] just musing if tension is a culprit , matching expansion rates should help if it's chlorides , the right alloy should help old jim get those broken ends under a magnifier can you see grains or did it melt and erase the evidence ?
