WebRuthenium is a shiny, hard, silvery-grey metal. It is a polyvalent element with a very high melting point. This metal is a member of the platinum group and is classified in group 8 of the periodic table. Like the other metals in the platinum group, ruthenium is inert to most other chemicals. Recycling WebRuthenium is used most often as a hardening agent for platinum and palladium. The major alloy is Pt-Ru with 10-15% ruthenium. Special alloys with 30-70% ruthenium are used in applications in which resistance to severe wear and corrosion is required. Ruthenium is replacing iridium as a hardening agent because it is more effective and less expensive.
