Have bicycle chains ever been successfully made from alloys other than steel? Titanium or magnesium for example?
Ti has been madeTJeanloz

I don't know that you would call them successful. They were expensive and wore out in a hurry.

It didn't go into production, but a neighbor of mine was a sort of freelance engineer/inventor, and he developed a belt-drive bike. It was quiet and smooth and used a variable-sized pulley (like a car's CVT transmission) to give a range of gears. About the time he got it working right, indexed shifting came in and interest dropped to zip.
Ti chain = $1 per link ($120 total) and rapid wearKerry Irons

Mg would wear much faster than Ti. There's really no alternative to steel.
Is it about weightglia

If it is about the weight, try the SPAM hollowpin 89R chain which weighs in at ~270g, about 35g lighter than the Dura-Ace. It is steel as well but saves some weight while maintaining adequately strong. I have seen them for as low as $27.
