The Copper/aluminium binary alloy displays shape memory characteristics but has a transformation temperature that is generally considered too high for practical use. The addition zinc to the system ...

Dutch metal is composed of 84.5 copper and 15.5 of zinc. It is of a pale yellow color, and so malleable as to be capable of beating out into leaves, and so thin as to be employed for cheap gilding ...

The novel bulk copper-tantalum-lithium (Cu-3Ta-0.5Li) nanocrystalline alloy exhibits notable resistance to coarsening and creep deformation, even at temperatures near its melting point. The discovery ...

Though why the rest of the materials aren't listed could be because they're primarily a copper/zinc alloy, in other word's brass, of a relatively low copper content—63/37 Cu/Zn but some 70/30 Cu/Zn.

Scientists create ultra-tough copper alloy that is stronger than steel and can withstand temperatures of 1500 F; ... "A common alloy of copper is brass, where copper is mixed with zinc," Frail said.

Japan's 5 yen coin costs almost face value on pricey copper, zinc. Weak Japanese currency drives ... The 5 yen coin weighs 3.75 grams and is made from a brass alloy of 60% to 70% copper and 30% to ...

A team of researchers has developed a groundbreaking high-temperature copper alloy with exceptional thermal stability and mechanical strength. The research team's findings on the new copper alloy ...
