I think you will find the nico-press sleeves for aircraft are STEEL,not aluminum.

\I think you'll find that they come in:
Stainless steel
Copper, tin plated copper, and zinc plated copper.
and Aluminum.

The stainless ones are not that commonly used by homebuilders. They
require a lot of pressure to crimp and only used on stainless cables. Most
people use the copper-alloy/plated ones as appropriate for the cable

Unfortunately they are COPPER or COPPER with tin plating.

Mea Culpa! They are zinc not tin plated.

No you are right, for stainless cables they are tin plated. It's actually not the
tin plating that makes the difference here. They use a different copper alloy
in the tin plated version that's compatible with stainless (so says National
Telephone, the owners of the Nicopress brand).

The nicos were being sold beside the stainless and galvanized aircraft
cable. I'm not planning on risking my life to them but using them on
the check cables and drift cutters on the skis I'm building.

My thanks to all for the informative discussion. I am fabricating restraint
cables from the shoulder harness mounting back to the tailwheel. I had hoped
to get the pieces at Home Depot Aircraft Supplies, but ran into the aluminum
fittings. I'll wait until I can get to the Real Aircraft Store.

I used to belong to a group that used a big levelwind reel, hooked to a 350
Chevy V8, to jerk a KA7 into the air. We had a 1000 M of 4mm cable that was
spliced with Al sleeves. we never had an Al sleeve fail, although we used to
break the cable fairly often. If I remember right all the control cables on
the KA7 were joined with Al sleeves. I think they are used on the late model
German glass planes too. With two swaged Al sleeves, I think you would break
the cable, before the sleeves failed.

You better check that the cable and the sleeves are compatible for the long haul.
The galvanized cable and stainless steel take different nicopress alloys.

I checked some different sites on this and found that aluminum sleeves
will only carry half the strenth of the cable while copper will
develop nearly full strength. Also AL and stainless don't get allong
with each other very well. I'm going to use copper or tin plated
sleeves.
Thanks for the help Drew Dalgleish
