Overview
C93700 is a popular tin/lead alloy. This high lead alloy has score resistance, structural uniformity, shear properties, compressive strength, and low cost. Additionally, the lead aids in good thermal conductivity. This material holds up well in tough environments. Large bearings for ships would be an excellent use case.
