any reason to use copper ferrules over aluminum? why don't they sell 5/64 copper ones?

Stainless steel cable use only. Aluminum ferrules will fail if used on SS cable in wet environs.

This.




they do. I have used lots of them. Got them from Newt

checked his site and didn't see any in 5/64

His site doesn't show them.You could use 1/16" and open them up with a 3/32" bit or use 3/32" copper ferrules but they would be too bulky to suit me.I don't think the snare shop shows them either.

1/16th fits 5/64th as well. 3 bags of them in my shop right now, using them on 5/64 stainless.

I have had this same problem. I will look for newts website.

Copper Ferrules ----- 1/16" fits 5/64" Stainless Steel cable. I'v built 1000's of Stainless Snares with them

Can I use copper on galv cable? Why not? Cost?

No. Same reason you can't use aluminum on stainless. You get galvanic corrosion.

Sure you can! Copper is required for aviation use, whether the cable is stainless or galvanized. No aluminum allowed. Copper is stronger.

I have run aluminum skiffs in saltwater, in Alaska, for 30 years. I use ALL stainless screws, and bolts. I have never had a problem with galvanic corrosion.

It's Aluminum and copper that don't mix.

And you have a Zinc sacrificial anode on the hull.
Any Galvanized steel plumbing requires a brass fitting between it and copper pipe.

I've had aluminum ferrules on SS cable for years . Never , EVER have I had a failure .......Never !

If you keep em dry you can avoid the problem.

Mine are wet all the time. Been boiled to die for over six years now . Wet in the ground and in water at beaver sets as well.

Aluminum double ferrules ,, $6.50 per 100 . Copper double ferrules $15.00 per 100.

And galvanized cable is cheaper than stainless.

Here is a little information about galvanic action.
