need high aluminum content nickel allow

I need some tubing and round rod made of like 90% aluminum and maybe 5% nickel and 5% iron.
Are there any commercial alloys in that ball park?
It needs to be light weight and magnetically soft but not too soft. It needs to retain a magnetic field but not be very hard to re- magnetize. It needs to hold up to !000 degrees F and be somewhat corrosion resistant. Its OK if it loses its magnetic hysteresis at that temperature.
Its OK to have other elements but I'm looking for something light weight. Its OK for the tubing to have less aluminum, mainly the rod material needs to be light weight.
Hot hydrocarbon vapors will be flowing through the tubing and around the rod but I'm trying to achieve plasma hydrocarbon cracking more than catalytic cracking.
Anybody have suggestions of available materials, especially for a light weight aluminum alloy that is slightly magnetic.
Thanks, gjbugh
