Evening all, I have been sent a piece of 'mystery metal' to make some heli parts from. The sender told me its 6Al4V Ti, which by all accounts is a PIG to work with. However it isnt... which leads me to suspect its not Ti but a
7000 series Alloy. Its about the same density as ally, just by hand comparisons, and its not magnetic. about the only simple test I can think of is to just melt an offcut (Ive already made some parts). If I can melt it before it gets red its ally of some sort, if not it might be Ti, and people are 'bigging up' how hard it is to machine.... any other simple tests anyone can think of or comments?cheers
Dave
