Beryllium Copper Wire – Process & Quality Assurance Statement
Our beryllium copper wires (C17200, C17500, C17510) are engineered for demanding applications that require the unique combination of high strength, conductivity, and reliability, where ordinary copper alloys would fall short.

Key process features

Production follows a tightly controlled metallurgical route to fully develop the alloy’s precipitation-hardening potential:
●Alloy Melting: High-purity copper is alloyed with precise beryllium additions under protective atmosphere to prevent oxidation.
●Casting & Hot Rolling: Ingots are cast and hot rolled into rods with uniform composition and refined grain.
●Solution Annealing: Rods are heated to dissolve beryllium, followed by rapid quenching to create a supersaturated solid solution.
●Cold Drawing: Multiple controlled drawing passes achieve final diameter and improve surface finish.
●Age Hardening: Low-temperature precipitation aging develops peak strength (C17200) or conductivity (C17500/C17510) while maintaining balance.
●Finishing: Wires are bright annealed or hard drawn as required; optional coating or cleaning applied.
●Protection & Packaging: Wires are spooled or cut and protected to prevent discoloration during storage and international shipping.

Quality control system

● Full traceability from raw alloy melt to finished wire
● Material test certificates and heat treatment reports supplied with every shipment
● Sample retention ≥3 years for third-party verification (SGS, BV, TÜV, etc.)
● 100% inspection of critical parameters:
• Chemical composition (optical emission spectrometry)
• Mechanical properties (tensile, yield, hardness, and conductivity on multiple samples)
• Dimensional accuracy (laser micrometers; typical diameter tolerance ±0.005mm)
• Surface quality and finish (visual + profilometer checks)
• Internal soundness (eddy current testing)
● Internal standards exceed ASTM B197 requirements. Typical properties:
C17200: Tensile strength ≥1200 MPa, Yield strength ≥1000 MPa
C17500/C17510: Electrical conductivity 45-60% IACS, Excellent fatigue and spring performance.
● ISO 9001:2015 certified facility ensures every beryllium copper wire delivers the superior strength, conductivity, and reliability your high-performance applications demand.
