Brass for CNC-machined threaded fittings, connectors and instrument components. Free-machining and lead-free brass grades differ in cutting behavior and compliance requirements. Specify the alloy rather than only naming brass.
How should I select the grade?
Free-machining and lead-free brass grades differ in cutting behavior and compliance requirements. Specify the alloy rather than only naming brass. Material availability, stock size and certificate requirements are confirmed during quotation; a listed grade is not a stock guarantee.
What affects machining and inspection?
Review lead restrictions, conductivity, plating compatibility and dezincification exposure. Functional tolerances depend on part geometry, material condition, fixturing and measurement method, not only the material family.
What should I specify for finishing?
State the finish standard, thickness, color or texture, masking and functional surfaces. Consider coating build in fits and threads. Approve any material or finishing substitution in writing.
Material quotation checklist
Send the exact grade and condition, 2D drawing, STEP model, quantity, critical features, service environment and traceability requirements. Tecpreva can review machining suitability and proposed alternatives before production.
