If you want to make some electrodes for electrochemistry, titanium strips are the way to go. It's rather interesting metal, and it's really hard, but can be cut with standard metalworking tools. Titanium filings are highly flammable, just like iron filings. But not everything is what it seems… this quick video on titanium and passivation electrochemistry tells why it makes it a bad anode if used without further treatment.
Watch this science video tutorial from Nurd Rage on how to passivate titanium metal for electrochemistry with Dr. Lithium.
