Model a simple one-for-one substitution when one alloy component is replaced by another. See the exact mass transferred and the percentage impact on the target batch.
A ratio of 1 means equal mass replacement. A different ratio can be used when your process specification deliberately calls for a mass-adjusted substitution.
Replacing one alloy metal with another by equal mass does not imply equivalent colour, hardness, melting behavior, density or metallurgical performance.
Replacement density can help estimate the volume occupied by the replacement metal.
Yes, when the replacement ratio is above 1.
