Most of these alloys were combinations like copper-silver or silver-gold and used with so-called hard soldering. That’s a technique still used today to join precious and semi-precious metals ...

Two 2,300-year-old swords discovered in a Celtic Iron Age necropolis in France "have few equivalents in Europe," and one is ...

The Cu-3Ta-0.5Li nanocrystalline alloy exhibits resistance to coarsening and creep deformation, even at temperatures near its melting point. The orange-colored features represent copper matrix atoms, ...

In a first, researchers have developed a new copper alloy that's one of the most resilient copper-based materials ever made. The new alloy, a mixture of copper, tantalum and lithium, was built on ...

It offers various copper alloys as castings and forgings, such as oxygen free copper, oxygen free copper with silver and phosphorus, beryllium copper, copper chrome silicon nickel, chrome copper ...
