Passivate


  • Chemical treatment used on Stainless Steel
  • Process makes no dimension changes in the part
  • Treatment removes iron particles and creates an etched passive surface. (Nitric acid -- dissolve's iron)
  • Process purifies the surface and improves corrosions resistance.

Tin


  • Electroplated tin provides very good resistance to corrosion.
  • When applied to a proper thickness this finish meets a 24 hour 20% salt spray requirement.
  • Can be soldered
  • Is ductile
  • Available either bright or dull finishes
  • Bright tin looks cosmetically better then dull tin and has better corrosion resistance. When exposed to low temperatures (-40° F) this finish changes structure and loses adhesion.
  • The expected shelf life of Electro Tin is approximately six months from the date plated. To ensure maximum shelf life -- parts should be sealed in an airtight container with desiccant.
