Often said to possess a reddish hue, there were many hints that orichalcum might be a form of brass – an alloy of copper and zinc – although its precise identity wasn’t revealed until ...
The observations were made upon two large cast copper crystals joined at a natural boundary which lay almost perpendicular to the external surface of the sample. Into this bicrystal, zinc was ...
Such are the general conditions which should be followed in making alloys. Copper melts at 1920 Fah. ; zinc at 700 Fah. ; lead at 590 Fah. ; tin at 450 Fah. ; cast-iron at 2100 Fah. A dull red ...

US’ new copper alloy resists 1,472°F heat for 10,000 hours, matches superalloy powerResearchers in the US have developed a new copper alloy that shows minimal loss of yield strength even at temperatures near ...
Researchers from the U.S. Army Research Laboratory (ARL) and Lehigh University have developed a nanostructured copper alloy ...
Made of 95% copper and 5% tin and zinc alloy, it sold for $1.7 million in 2010 but is valued at $2.3 million in mint uncirculated condition. More recently, it went for $840,000 at an auction.
For example, brass is an alloy of copper and zinc. It is stronger than copper or zinc alone. Copper and zinc atoms are different sizes. This distorts the regular lattice structure in brass ...
