C93700 leaded tin bronze is a high-lead cast alloy. Review C93700 bronze properties and C93700 hardness against the actual casting product and test basis; neither a short name nor a reference value establishes finished bearing performance.

Your C93700 machining quote should compare the same stock route, drawing revision, free or installed acceptance and receiving evidence.
C93700 is a high-leaded cast tin-bronze designation. Identify the product standard and casting route, then define the actual bearing, bushing or guiding interface.
Selected Concast data gives an indicative cutting index of 80. It does not predict your cycle time, tool life or quote cost; review actual stock, support, geometry and final surface.
Provide CAD and controlled drawing, exact material and casting specification, usable stock, quantities, mating parts, lubrication inputs, final surface and receiving evidence.
Specify feature limits, datums, support and free or installed acceptance. The reviewed quote confirms geometry and inspection scope; no universal tolerance is promised.
State the ordered standard and revision, casting route, product form, lot identity and certificate contents. Keep material records separate from dimensional and functional acceptance.
Review full chemistry, product requirements, working conditions, lubrication and final fit. These are distinct alloys; obtain drawing-authority approval before substitution.
Yes. The selected Concast continuous-cast reference gives Pb 8–11%. Confirm the exact ordered material and application requirements before approval.
