Large Custom-Forged CuCrZr Round Plate – Process & Quality Assurance Statement
Our large custom-forged CuCrZr round plates are engineered for heavy-duty, high-temperature applications where sustained conductivity and mechanical strength are critical, delivering superior performance compared to rolled or cast alternatives.

Key process features

Production combines advanced open-die forging with precise heat treatment to achieve optimal precipitation hardening in substantial sizes:

●Alloy Preparation: High-purity copper is alloyed with precise chromium and zirconium additions in controlled induction furnaces under protective atmosphere.
●Billet Casting: Semi-continuous casting produces large, dense billets with homogeneous composition and minimal segregation.
●Preheating & Forging: Billets are uniformly heated and forged under high-tonnage presses into near-net round plates, refining grain structure and achieving excellent density.
●Solution Heat Treatment: Plates are solution annealed at high temperature and rapidly quenched to create a supersaturated matrix.
●Precipitation Aging: Controlled low-temperature aging develops peak hardness, strength, and conductivity balance.
●Precision Machining: CNC milling and turning achieve exact diameter, thickness, and surface finish per customer drawings.
●Final Protection: Thorough cleaning and light oiling prevent oxidation during storage and global shipping.

Quality control system

● Full traceability from raw alloy melt to finished round plate
● Comprehensive 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, hardness, and conductivity tested at multiple locations)
• Dimensional accuracy (CMM and ultrasonic thickness; typical tolerance ±0.5mm)
• Surface quality and flatness (profilometer + visual checks)
• Internal soundness (full ultrasonic scanning)
● Internal standards exceed ASTM B768 requirements. Typical C18150 aged properties:
Tensile strength ≥450 MPa, Hardness ≥140 HB, Electrical conductivity ≥80% IACS, Excellent stability up to 500°C without significant softening.
● ISO 9001:2015 certified facility ensures every large custom-forged CuCrZr round plate delivers consistent, reliable performance in your most demanding high-temperature and high-conductivity applications.
