Copper and Aluminum Don't Mix

[Obi-Dar Ke-Gnomie]

you shouldn't NEED a brass buffer unless you want it aesthetic reasons.

Because, we all know that copper and brass look good together...

Nah, it's just the knowledge that there is a CF in there

Corrosion Found.

I have corosion between my Lux V and my copper heatsink. Any suggestions?

[Shadar Al'Niende]

give up?



seriously... thermal tape? don't know what else to tell you...

[polarcupz]

give up?

I will NEVER give up. There must be a way. Thermal tape might work. I haven't tried it yet, but it would keep the two apart. I hadn't opened the saber up in a while(1 yr maybe?).

[FenderBender]

For a while, we used thermal grease. We opened up a saber we did a year ago for an upgrade and there was no corrosion. The heatsink was a little tarnished, but no evident deteriation otherwise. This thread really is pointless to continue. IT'S NOT A BIG DEAL.

You're sure its not just the patina of the heatsink?

[polarcupz]

I will try to get a pic when I get home. Oh and thanks fender, that is really nice of you, very supportive. Whatever. It is all over the bottom of the lux V, not as much on the copper...but that is how the corrosion is supposed to work (copper will eat away at the aluminum).

If this thread should not be continued I will let it die, along with my lux V.

I've been using the copper heatsinks in my personal MHS sabers for two years, and have not had an issue with corrosion in any of them, nor have any of my led's died. i've always ued either the thermal paste he mentions, or the star-shaped thermal tape Tim sells here in the store when I mount the led's. What Fender says is true...it's really not a big deal. Do you really think if it wasn't safe, that Tim would be selling copper heatsinks in the first place?

Aluminum and cast iron don't mix either, yet auto manufacturers have been using aluminum cylinder heads on cast iron engine blocks for decades....the reason they can do it? The head gaskets separate the two metals enough that the corrosion never happens. It's the same with the thermal tape and your led's aluminum base plate.

Yeah... what he said.
Jay always has the most thorough explanations.
