C18070 CuCrSiTi alloy is predominantly copper (Cu) with alloying components chromium (Cr), silicon (Si), and titanium (Ti). C18070 is the most distinctive and unique alloy because of the specific combination of alloying elements. It is made for extreme environments due to its remarkable combination of high strength and hardness. C18070 CuCrSiTi Alloy Foil Strip exceeds the ratio of standard coppers in tensile strength, toughness, and hardness, making it perfect for applications involving high-friction and heavy loads. These attributes and their multi-welding method, including braze, arc, and laser, provide excellent CuCrSiTi Alloy Foil Strip interoperability. It is compatible with closure mechanisms and surface treatment, and it will not crack.
