Naval Brass Stock
CDA lists lead limits: C46400 (Uninhibited), 0.20% maximum; C48500 (High Leaded), 1.3% minimum and 2.2% maximum.
Limits are not batch measurements.
Shared copper/tin ranges do not establish equivalence.

Offers
Hypothetical example: a factory requests C46400 blanks; a supplier offers C48500.
Compare it as a substitution, not the same item.

Order
Specify the selected UNS alloy, form, section, temper and cutting requirement.
Record the supplier and proposal reference.
