Extremely High-Strength Titanium Copper Foil C1995-GSH
for Auto-focus camera module
Summary
Employing advanced thickness control techniques developed in the manufacture of treated rolled copper foil for flexible printed circuits, we have developed extremely high-strength titanium copper foil with outstanding properties including strength, electrical conductivity, fatigue resistance, and thermal resistance.
This product has the world's highest tensile strength of any copper alloy foil, at 1,540 MPa, and contributes to improved reliability of camera modules for smartphones as a spring material for lens support.
Application Examples
Benefits for Customers
Extremely high-strength titanium copper alloy foil C1995-GSH, which has even higher strength and fatigue properties than the conventional titanium copper foil C1990-GSH, contributes to improving the reliability of superior spring properties and module strength.
Features of Titanium Copper Foil Chemical composition : C1995 Cu-4.0%Ti / C1990 Cu-3.0%Ti
| Alloy | C1995-GSH | C1990-GSH |
|---|---|---|
| Standard thickness | 27.5µm～ (Aiming for even thinner foils !) |
In mass production：25µm～ Prototype：18µm～ |
Extremely high strength can be achieved by controlling microstructure at nano scale level (<100 nm) using JX's core rolling technology.
