C17200 strips excel in high-stress, high-conductivity scenarios like electronics and precision tooling. Key advantages include factory-prehardened tempers (reducing post-processing) and superior fatigue resistance.
Thickness: 0.1mm ~ 0.6mm
Width: 5mm ~ 300mm
Key Characteristics & Advantages:
C17200 beryllium copper strips 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 strips (e.g., O, 1/4H tempers) allow direct stamping without post-treatment, reducing production time.
