Standard Designation System for Copper Alloys and Copper. There are over 300 types of copper alloy and wrought copper available. The Copper Development Association has established a numbers naming system comprised of alloy metal numbers is utilized in the United States and Canada.
Classification: Copper and copper alloys are considered an "article" and are not hazardous in its solid form. However, certain processes such as cutting, milling, grinding, melting and welding could result in some serious hazardous materials being emitted. The GHS classification below pertains to these emitted products during these processes.
Copper Alloys Over the years, as new uses for copper have been discovered, so too have an entire range of copperbased alloys developed to meet specific needs and applications. Copper alloys are metal alloys that have copper as their principal component. They .

The term "mill finish" is commonly used for an "as fabricated" finish. Asfabricated finishes can be marred by secondary operations such as bending, milling and welding, in which case, they may require additional finishing operations. They can also vary in appearance, both intentionally and accidentally.
Standard Classification for Temper Designations for Copper and Copper Alloys— Wrought and Cast1 This standard is issued under the fixed designation B 601; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
The copper ore enrichment process is a mechanical process of recovering ore before it undergoes smelting. It is composed of four main stages: mined ore crushing, milling, flotation and drying. The crushing process prepares fresh ore ( % of pure copper) from copper mine to milling process.
These copper standards are helpful in guiding metallurgical laboratories and refineries, product manufacturers, and other endusers of copper and its alloys in their proper processing and application procedures to ensure their quality towards safe use. List of copper standards developed by ASTM:
