What is Iridum ?
I put my new iridums in and now everyone I tell about them ask
What is Iridum ?
Well
I think it's something that Superman is SCARED of .
Could someone enlighten me.
I tried looking it up on the internet and found not only spark plugs but cell phones ?
I know my smart a ( I really love him ) son in law will hit me with that one today.
Thanks

Iridium is white, similar to platinum, but with a slight yellowish cast. It is very hard and brittle, making it very hard to machine, form, or work. It is the most corrosion resistant metal known, and was used in making the standard metre bar of Paris, which is a 90% platinum-10% iridium alloy. This metre bar has since been replaced as a fundamental unit of length (see Krypton).
Iridium is not attacked by any of the acids nor by aqua regia, but is attacked by molten salts, such as NaCl and NaCN.

I may have to make me a cheat sheet.
This is GREAT.
Thanks will wow everyone today.

The scientific answer is; it is an element. An element is a substance composed of atoms having an identical number of protons in each nucleus. Elements cannot be reduced to simpler substances by normal chemical means.
-Iridium-
A very hard and brittle, exceptionally corrosion-resistant, whitish-yellow metallic element occurring in platinum ores and used principally to harden platinum and in high-temperature materials, electrical contacts, and wear-resistant bearings. Atomic number 77; atomic weight 192.2; melting point 2,410°C; boiling point 4,130°C; specific gravity 22.42 (at 17°C); valence 3, 4.

They're also supposed to be pre-gapped by the factory (Denso?) and not adjusted because the tool can damage them, according to previous posts.
