Quick Detail:
C19900 is a precipitation-strengthened beryllium-free copper-titanium alloy. As an eco-friendly alternative to conventional beryllium copper, it balances high strength, excellent elasticity and reliable electrical conductivity.
Thickness：0.02mm ~ 0.6mm
Width: 5mm ~ 300mm

Key Characteristics & Advantages:

1.Free of beryllium, meets global environmental requirements for electronic components.

2.Outstanding resistance to stress relaxation at elevated temperatures; contact force remains stable after reflow soldering.

3.Superior fatigue resistance and creep resistance for long-term cyclic spring loading.

4.Good formability and plating performance (suitable for nickel plating, gold plating).

5.Fine, uniform metallurgical structure, consistent performance in mass stamping production.
