Beryllium Copper Rod – Process & Quality Assurance Statement
Our beryllium copper rods (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: Rods are straightened, cut to length, and optionally ground or polished.
●Protection & Packaging: Surfaces are cleaned and protected to prevent discoloration during storage and international shipping.

Quality control system

● Full traceability from raw alloy melt to finished rod
● 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 ±0.05mm)
• Surface quality and straightness (visual + profilometer checks)
• Internal soundness (eddy current or ultrasonic scanning)
● Internal standards exceed ASTM B196 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 rod delivers the superior strength, conductivity, and reliability your high-performance applications demand.
