Metal Alloy Table

Metal Alloy Table

I put together a Metal Alloy Table on my A&S website, Gaeira's Anvil.

This table helps to organize the variety of information I found online about Copper and Silver alloys which are spread over many sources and can be confusing. From several years of online searches I found that jewelry and metal supplier rarely used the same name for an alloy, they often used different terms which can lead to confusion and potentially purchasing an incorrect metal alloy than what one wanted. 

CDA #: Copper Development Association's standards ID number can be written in many different ways and yet mean the same thing. 

For example CDA #752 or CDA 752 or Alloy 752, etc., can be referred to as Nickle Silver, German Silver, Nickle Alloy, or another term, each is a mix of: 17% Zinc (Zn), 18% Nickle (Ni), and 65% Copper (Cu).

"There are more than 400 copper alloys (Brass, Bronze, Nickel Silver, Gunmetals, etc.), each with a unique combination of properties, to suit many applications, manufacturing processes and environments." SOURCE

Copper is a Family of Alloys: "For many applications, properties of copper can be readily customized. This is achieved by alloying: making a new metal out of two or more different metals. The most well-known copper alloy families are brass (copper-zinc), bronze (copper-tin) and copper-nickel. These actually represent families of alloys, all made by varying the amount of specific alloying elements. Alloys can be made to achieve certain colors, improve strength or corrosion resistance, improve forming or joining properties, or achieve any number of specific demands that the individual elements can't achieve on their own. By combining copper with other metals and adjusting the percentages, alloys are made to fit almost any application."
