C360 Brass Blanks
C360 Brass Blanks FAQs
When purchasing C36000 (CDA 360 / CuZn39Pb3 / 2.0380 / HPb59-1) free-cutting brass, overseas buyers frequently face capital lockup due to volatile metal market prices, expensive shipping fees for full bars or sheets (paying freight on dead-weight scrap), a lack of local high-efficiency multi-axis sawing and block squaring equipment, and messy chip management or oxidation issues during batch machining. We provide flexible, small-batch, cut-to-size C360 blanks with front-end pre-machining - including precision sawing, NC waterjet cutting, 6-side milling/grinding, trepanning, and anti-tarnish chemical passivation. Clients receive clean, ready-to-machine blanks that load directly into high-speed CNC machinery.
What you may want to know about C360 Brass Blanks
C360 Brass Raw Material Sourcing, Export Credentials & Heat-Lot Traceability
At FlexiTurn, resilient non-ferrous supply chains, transparent traceability, and compliant export capabilities form the core of our C360 Brass Blanks service:
Compliant Sourcing from Primary Mills: We source exclusively from primary mills certified to ASTM B16 (bars), ASTM B36 (plates), or EN 12164 (CuZn39Pb3) standards, strictly controlling Cu, Pb, Fe, and Zn ratios to ensure zero internal porosity, shrink voids, or micro-segregation for consistent hardness and chip-breaking behavior.
End-to-End Heat/Lot Number Tracking: From raw material intake, waterjet cutting, sawing, grinding, 6-side milling, and trepanning to chemical passivation and final packaging, every individual blank or bundled unit is tagged with its original furnace heat and batch control numbers for 100% lot traceability.
Complete Certification & MTR Documentation: Every shipment includes an EN 10204 3.1 Mill Test Report documenting spectral chemical analysis, tensile strength, elongation, and hardness (HRB/HV) test results.
Moisture, Anti-Oxidant & Impact-Proof Export Packaging: All pre-machined C360 brass blanks undergo degreasing washing and anti-tarnish passivation, sealed in moisture-proof plastic film with desiccant packs. They are secured inside fumigation-free export wooden crates with reinforced padding to prevent tarnishing or impact denting during ocean transit.
C360 Brass Core Pre-Machining Services: Precision Sawing, Milling, Trepanning & Passivation
To meet high-speed turning, pneumatic fitting, and electrical connector manufacturing workflows, FlexiTurn offers versatile pre-processing capabilities for C360 free-cutting brass:
High-Speed Sawing & Cold NC Waterjet Cutting: Utilizing high-speed CNC circular saws dedicated to non-ferrous metals and ultra-high-pressure waterjet systems, we cut C360 extruded bars and thick plates to exact dimensions with burr-free edges and tight cut-off tolerances (±0.1mm).
6-Side Milling & Surface Squaring: We perform 6-side rough milling and squaring on block-shaped valve, lock, or connector blanks, stripping scale and oxidation to provide clean reference datums and precise perpendicularity.
Trepanning & Annular Core Cutting: For large-diameter solid brass bars or thick plate rings, dedicated trepanning tools slice out internal voids while saving the solid center core for reuse as smaller nuts, pins, or washers, dramatically reducing raw material waste on expensive copper alloys.
Anti-Oxidant Chemical Passivation: We apply environmentally friendly anti-tarnish immersion treatments that form an ultra-thin transparent protective layer on the brass surface, isolating moisture and preventing patina or dark spot formation.
Quality Control & Surface Integrity in C360 Brass Pre-Machining
Because brass is relatively soft and susceptible to scratching and atmospheric tarnishing, process control is strict:
Optical Emission Spectrometry (OES) & Hardness Checks: We perform OES spectral analysis to check Cu and Pb ratios, alongside Webster or Rockwell (HRB) hardness testing to verify Half-Hard (H02) or Soft Annealed temper compliance, preventing tool wear from overly hard material or stringy chipping from overly soft stock.
Dimensional & Geometrical Inspection: Utilizing micrometers, calipers, and profilometers, final inspections are conducted on cut lengths, milling parallelism, and surface finish before dispatch to leave optimal machining allowances for automated high-speed turning equipment.
Surface Cleanliness & Anti-Tarnish Verification: Degreasing effectiveness is thoroughly verified to ensure zero chip residue, cutting fluid, or oil stains, followed by humidity chamber testing to guarantee export quality standards.
C360 Brass Client Value & Fulfillment Assurance
By choosing FlexiTurn's custom C360 brass precision blanks and pre-machining services, overseas buyers gain distinct competitive edges:
Mitigating Metal Market Risks & High MOQs: Avoid mill-scale tonnage commitments or stockpiling full bars/sheets, purchasing exact pre-cut blank dimensions and quantities to optimize cash flow.
Unlocking High-Speed CNC Capacity: Front-end sawing and 6-side squaring allow immediate high-RPM finishing locally, drastically shortening cycle times per part while preserving local machinery.
Seamless Customs Clearance & Compliance: With full export qualifications, authentic 3.1 MTRs, and industrial certifications, high-value non-ferrous alloy shipments clear customs smoothly while meeting destination country technical standards.
