What is Bender (from Futurama) physically constructed out of? He mentions several times that he is "XX% titanium/lead/etc" but I don't recall the specific materials and proportions.

This question What are Bender's computational specifications? deals with his computational specifications but I'm interested in the physical composition of his body.

    Don't forget his nickel impurity

The list of Bender's claimed composition adds up to over 100%, so he can be a dubious source (episode codes in brackets):

  • 40% Zinc (1ACV13).
  • 40% Titanium (2ACV03).
  • 30% Iron (3ACV22), presumably mixed with osmium, (3ACV17).
  • 40% Dolomite (4ACV07).
  • 40% Lead (video game).
  • 40% empty (s07e09)
  • 40% back (s7e21 Assie come back)
  • 0.04% Nickel impurity - (3ACV17 - A Pharaoh to Remember)

There was also a claim that he was 40% chromium (not made by Bender but by someone else - 6ACV03). In addition to those, he's also claimed to be 40% horseshoes (ITWGY), 40% Wire (7ACV03) and 40% scrap metal (6ACV23), either of which could be any of the above metals or something else.
