You are right. A "lead free future" is coming to this industry. It may be
driven by market factors or by politics.
Let's use toxicity and environmental data not to refute the fact that lead
free is coming, but to instead help select the proper alloy. Toxicity,
fatigue, conductivity, etc, etc. should all be included in lead free alloy
selection.
