What is an helicopter ( probably a French Alouette dating back to the 50' ) stainless, whitish rotor made of? Is it worth anything?

If it is stainless steel, scrap Grade 304 is going for $1,100 per ton....You have any pix. of it to post ?

Welcome to Tnet.

The exact composition will vary according to the model, but it's not going to yield valuable scrap. For example, from that era, the main rotor blades of the Alouette II series had an extruded aluminium alloy main spar which formed the leading edge of the blade. The aerofoil section and trailing edge of the spar were made from thin gauge aluminium alloy, packed with a synthetic resin foam filler to give rigidity to the skin.

By the end of the 1950s, the Alouette III series had been designed with essentially the same construction but with the addition of stainless steel leading edge coverings

Thanx, no pix for the moment. It's an helicopter (remains of) I discovered back in the early eighties in the forest and I didn't go back there since.

It is white, unaltered, unlike the rusted iron part it is fastened to (by 8 or10 bolts). No pics for now. Thank you anyway.
