Thickness: 0.02mm ~ 0.099mm
Width: 2mm ~ 200mm

Key Characteristics & Advantages:

C17200 beryllium copper foil combine exceptional strength with high electrical/thermal conductivity, making them ideal for demanding applications:

Strength & Elasticity: After aging treatment, tensile strength reaches 1105–1480 MPa, hardness up to 44 HRC, and elastic modulus of 128 GPa, outperforming phosphor bronze or aluminum bronze.

Conductivity: Electrical conductivity ≥18% IACS and thermal conductivity of 105 W/m·K, enabling efficient heat dissipation in electronics.

Durability: Resists corrosion, fatigue, and wear; non-magnetic and non-sparking (critical for explosive environments).

Formability: Pre-hardened foil (e.g., O, 1/4H tempers) allow direct stamping without post-treatment, reducing production time.

Core Applications:

6G application, Medical equipment, FPC (soft PCB) , Geophone etc.
