Hi Inge - yep, I try to use the SI system as much as possible, if for no other reason than to confuse Doug - he was trying to measure some IC results in fortnights per stone last week! And I was being lazy on the density as I figured the value existed without me having to do the calculation. Technet has produced 2 values for me so I appreciate everyone's assistance.

If he does not answer, I'll look in my pile, but it will take time. You use kg/m3 ! Are you really a american? You can calculate yourself: 1/q = Ftin/Qtin + Flead/Qlead in wich F is the mass fraction and Q is the density of the respective elements For more elements, just add : 1/Qalloy = Felement1/Qelement1 + Felement2/Qelement2 + etc all must be in solid state at +20C /Inge On 31 August 2011 14:08, David D.
