Abstract
A metal canister that is used in the fabrication of an item, the metal canister comprised of a first metal layer, and a second metal layer that is clad to the first metal layer so as to form a sheet stock, wherein the first metal layer comprises Tantalum and the second metal layer comprises Niobium or Molybdenum. The first metal layer of Tantalum is on an inner surface of the canister when formed. The canister can be comprised of more Niobium (or Molybdenum) than Tantalum, more Tantalum than Niobium (or Molybdenum), or approximately equal amounts of each of the Niobium (or Molybdenum) and Tantalum. The sheet stock can be clad together by mechanical bonding under high pressure of at least 1,000,000 psi. Prior to cladding, the materials can be subject to a brushing to deoxidize the materials.
