Beryllium Copper Strip – Process & Quality Assurance Statement
Our beryllium copper strips (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 coils with uniform composition and refined grain.
●Solution Annealing: Strips are heated to dissolve beryllium, followed by rapid quenching to create a supersaturated solid solution.
●Cold Rolling: Multiple controlled reductions achieve final thickness and improve flatness.
●Age Hardening: Low-temperature precipitation aging develops peak strength (C17200) or conductivity (C17500/C17510) while maintaining balance.
●Slitting & Finishing: Coils are precision-slit to width and cut to length or supplied as coils; optional polishing or coating applied.
●Protection & Packaging: Surfaces are cleaned and protected with film or oil to prevent discoloration during storage and international shipping.

Quality control system

● Full traceability from raw alloy melt to finished strip
● 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 (micrometers and laser gauges; typical thickness tolerance ±0.005mm)
• Surface quality and flatness (visual + profilometer checks)
• Internal soundness (eddy current or ultrasonic scanning)
● Internal standards exceed ASTM B194 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 strip delivers the superior strength, conductivity, and reliability your high-performance applications demand.
