# Titanium can be used as a Substitute for Aluminum  Member mv If I understand it correctly, titanium does not oxidize like aluminum. Smarter members will have to verify that for me. I abandoned the use of aluminum because of the oxidation that may occur with long term storage. Titanium flake used in the same proportion as aluminum in EPH25 produces intense sparks. I mesh -45 to 150 [Shop for Titanium (eBay)](https://www.ebay.com/itm/404393429561?hash=item5e27ba0a39:g:iwUAAOSwndhkl5AH&amdata=enc%3AAQAIAAAAwAjKhr%2BOuGEYl4od18VDnL1p7Eejjys6B0zqEVe6m5hJhUAj4sMx3MHSepcdpvQFVbkFjw06Tl78LaPdGbJ0GSCD4OLkkaTrLeU2MJxCE2R9bSTvEtRXJILCLHVjxK33hmqEqxGT2Rt0RkTucwWKvBTLWTUf9Ad6gWObVm7UM5szt76%2BS1DjKvZ3n5Nrt4HS3EIFjGPQ0CE2y%2FrcaNcdHUa2rWrmUgJ1mVlno53omnEhGxstgATZ1UER7xUd1yTuaw%3D%3D%7Ctkp%3ABk9SR-jXlOm3Yg) yes, same mesh as aluminum, if you can find it. I could not find that mesh so I opted for the -40+150 and it works great. The flakes look pretty big when you're grinding the glass with the titanium but it burns beautifully as you can see in the pic. I don't think you'd be disappointed. Bed time here,
