Still having problems with wire
I am working with wire that is 5183 alloy. I am trying to get at least .5 mil thickness so I can dye. The problem is that the piece keeps turning dark grey during the ano process before the time is up.
I am using calipers to measure the diameter and measuring the length of wire prior to coiling, so I have faith in my calcs for area. I am using the 720 calcs. to determine time. I am keeping tank temp at 68 to 70 and using the tank and pump that came with LCD kit.
I have tried everything from 2.5A/sqft to 27A/sqft to try and get enough thickness to take dye without having the wire darken. I started with 4.5A/sqft and reduced by .5 each run until I got to 2.5 when it wouldn't hold dye and still was very dark grey. I thought maybe higher amps w/ shorter time might help, so went the other way incrementally. Same problem!!! If I try and go over .25mil the wire turns dark grey and with that thin a layer it does not take color well, no matter how long I leave it in the dye.
I am at a loss of what else to try and really need help. I have posed this problem before and not gotten a lot of constructive help. Please help this time, I am running out of ideas.
