Melting of copper and beryllium.
To make beryllium copper alloy, beryllium is melted into copper, usually with a copper beryllium master alloy that contains a controlled amount of beryllium. The mixture is then cast into the desired shape and cooled to solidify, resulting in the beryllium copper alloy.
You may be thinking of Tellurium Copper (TeCU). Tellurium is an element (Te), and it's easy to confuse it with Beryllium (Be), another element. Both are often alloyed with Copper (Cu). BeCu can be heat-treated and is great for springs.
Copper is mined as copper it is not an alloy
Copper is just that pure copper. Beryllium copper also known as copper beryllium, beryllium bronze and spring copper, is a copper alloy with .5 to 3% beryllium and sometimes with other alloying elements. Beryllium copper combines high-strength with non-magnetic and non-sparking qualities. It has excellent metalworking, forming and machining qualities. It has many specialized applications in tools for hazardous environments, musical instruments, precision measuring devices, bullets, and aerospace.
Brass is an alloy made by combining copper with zinc. It is not a nonmetal; it is a metallic alloy.
alloy brass is a mixture it is made with copper and zinc
Here is beryllium. It is a kind of metal elements. It could be used into copper alloy and made up of beryllium bronze. But I have ever not heard baryllium. I think it is a miss spelling. Or eles youcan check the website www.sinomaterial.com, this page http://www.sinomaterial.com/products/Nickel-beryllium-alloy.htm has a baryllium in their web page title. but in their article here is the beryllium. So, I thik that is the beryllium.
Copper (symbol Cu) is not an alloy it is an element containing only atoms of copper.
Alloy magnesium and copper
bronze
Many wind instruments are made of Brass, an alloy of copper and zinc.
They were made from an alloy called bronze which is 95% copper.
