INSTRUCTIONS
  • Type in the appropriate values of the atomic weight and valence in the spaces provided and then hit the button entitled "Run Estimator".
  • You can rerun the calculator after receiving your answer by closing the answer window and entering new values in the spaces provided.
  • You can enter values for up to 5 elements in the alloy being considered.
  • Enter the weight percent in the first space, atomic weight in the second space and the expected valence in the third space, one element per line. ENTER VALUES ONLY - NOT THE ELEMENT NAME.
  • Make sure that three non-zero entries are made for each desired element
  • For the weight percent use either the value from the elemental analysis or the midddle of the range of values for that component as listed in the literature
  • Ignore components at 1 wt% or less
  • If you do not know the metal atomic weight, open the Table of Selected Atomic Weights for selected values
  • If you do not know the metal valence, open the Table of Selected Atomic Weights for selected values
  • Additional alloy atomic weights and valence values can be found in a number of tables or on some Periodic Charts of the elements.
  • See the the CALCTUTORIAL (Tutorial on CORCALC) for additional information on this calculation and how to choose the appropriate valence.

Enter the weight percent, atomic weight and valence for each element to be considered.
