A new study designed a copper-tantalum-based superalloy (with added lithium) that can operate up to 800 degrees Celsius (1472 degrees Fahrenheit). This nanoscale approach to building new superalloys ...

It has its melting point at 227°C, with the 0.05% of Ni promoting a shiny joint while lowering copper pad erosion. The 0.009% of Ge promotes wetting and prevents the formation of dross.

The strongest Cu-Ta-Li alloy developed to date exhibits outstanding strength and stability, making it ideal for advanced ...

At room temperature, the alloy’s yield strength of 1120 MPa is far superior to existing copper alloys. Additionally, the alloy displays lower creep deformation than other alloys with similar ...

Copper is a metal in group IB of the periodic table with the atomic number 29 and an atomic weight of 63.54. The metal has a density of 8.96 Mg/m 3 and a melting point of 1083 C. The electronic ...

A new copper alloy, a Cu-3Ta-0.5Li nanocrystalline alloy, exhibits remarkable resistance to coarsening and creep deformation, even at temperatures near its melting point. The orange-colored ...
