This lead-free brass composition ensures environmental compliance while maintaining superior mechanical properties.CW614N Brass (European Designation)CW614N represents the European designation for free-cutting brass with excellent cold working properties. This grade provides optimal balance between strength, ductility, and manufacturing efficiency.Chemical CompositionCopper (Cu): 58-60% Zinc (Zn): 39-41% Lead (Pb): ≤0.2% Iron (Fe): ≤0.3%Mechanical PropertiesTensile Strength: 370-430 MPa Yield Strength: 170-280 MPa Elongation: 20-30% Hardness: 80-120 HVPhysical PropertiesDensity: 8.5 g/cm³ Electrical Conductivity: 28% IACS Thermal Conductivity: 120 W/m·K Melting Point: 900-940°CFunctions & ApplicationsPrimary Functions of Brass Expansion InsertsThread CreationCreates permanent female threads in soft materials like wood, plastic, and composite materials without the need for tapping operations.Load DistributionDistributes fastening loads across a wider area, preventing material damage and ensuring secure connections.Corrosion ProtectionBrass material provides natural corrosion resistance in marine, outdoor, and chemical environments.Electrical ConductivityMaintains electrical continuity in electronic assemblies and grounding applications.Industrial ApplicationsElectronics & Electrical: PCB mounting, electrical enclosures, grounding applicationsAutomotive: Interior trim, dashboard assemblies, electrical connectionsMarine Industry: Boat fittings, deck hardware, navigation equipmentFurniture Manufacturing: Cabinet hardware, decorative fittings, structural connectionsHVAC Systems: Ductwork connections, equipment mounting, control panelsAerospace: Interior panels, avionics mounting, lightweight assembliesMedical Equipment: Device housings, mounting brackets, electrical connectionsRelated Technical Terms & SynonymsThreaded InsertsExpansion AnchorsSpreading DowelsPress-Fit InsertsBarrel NutsThread BushingsExpansion FastenersBrass AnchorsSelf-Expanding InsertsCompression InsertsMechanical FastenersThread ReinforcementHelical InsertsCaptive FastenersBlind Threaded InsertsTechnical CategoriesFastener Type: Expansion type threaded insertInstallation Method: Press-fit, hammer-in, pneumatic insertionMaterial Classification: Non-ferrous metal fastenerThread Standard: ISO metric thread (M4, M5, M6, M8)Application Category: Permanent threaded connectionInstallation Process & Technical GuidelinesStep-by-Step InstallationHole Preparation: Drill pilot hole to specified diameter with appropriate depthInsert Placement: Position brass expansion insert at hole entrancePress Installation: Apply steady downward pressure using press or hammerExpansion Activation: Insert expanding mechanism engages automaticallyFinal Verification: Check thread engagement and holding strengthInstallation Benefits: No special tools required • Quick installation process • Consistent results • Permanent solution • No thread cutting neededQuality Standards & CertificationsInternational StandardsISO 9001:2015 Quality Management EN 14399 Structural Fasteners DIN 7991 Thread Standards ASTM B16 Brass SpecificationsMaterial ComplianceRoHS Compliant Materials REACH Regulation Compliance Lead-Free Brass Composition Environmental StandardsTesting & ValidationPull-out Strength Testing Corrosion Resistance Testing Dimensional Accuracy Verification Material Composition AnalysisGet Your Brass Expansion Inserts TodayContact us for competitive pricing, technical specifications, and stock availability on all M4, M5, M6, and M8 brass expansion inserts.Why Choose Our Brass Expansion Inserts?✓ Premium CZ121/CW614N Brass✓ ISO 9001:2015 Certified✓ Fast Delivery Worldwide✓ Technical Support✓ Competitive Pricing✓ Custom Sizes AvailableFrequently Asked QuestionsWhat is the difference between CZ121 and CW614N brass?Both CZ121 and CW614N refer to the same brass alloy composition under different standard systems. CZ121 is the EN (European) designation, while CW614N represents the European material number for the same free-cutting brass alloy.Can these inserts be removed after installation?Brass expansion inserts are designed for permanent installation. While removal is technically possible, it typically requires drilling out the insert, which may damage the surrounding material.What pilot hole size should I use?Pilot hole diameter should match the outside diameter of the insert before expansion. Refer to our specification table for exact dimensions for each thread size.Are these inserts suitable for outdoor applications?Yes, brass expansion inserts offer excellent corrosion resistance and are ideal for outdoor, marine, and humid environment applications due to brass’s natural anti-corrosive properties.Get Your Custom Quote TodayReady to enhance your assembly with premium Brass expansion inserts, Brass Expansion anchors, Brass Expansion Fasteners and Brass Dowels? Email us for detailed brochure: sales@brass-copper-parts. com Call us directly:  91-22-43449300 WhatsApp for instant response:  91-22-43449300 Request technical consultation with our experienced engineers Custom solutions available for unique applications and specificationsContact us today for competitive pricing, technical support, and fast delivery worldwide!
