C14200 Alloy is a high-strength alloy composed primarily of copper (99%) and manganese (1%). The addition of manganese improves the strength of the material while still maintaining good electrical conductivity. It also contains small amounts of titanium, nickel, zinc, iron, lead, tin, chromium, antimony and phosphorus. This combination gives Copper C142 a unique set of physical and mechanical properties that make it ideal for use in many different industrial applications.

Mechanical Properties
The addition of manganese to grade C142 gives the material excellent tensile strength (up to 95 ksi) and yield strength (up to 45 ksi). It also has a high level of ductility which makes it easy to form complex shapes without fracturing or cracking. This makes it well-suited for applications such as deep drawing, where complex shapes are required. It has good machinability when working with cutting tools such as drills or reamers. It can also be welded using arc welding techniques such as TIG welding or MIG welding.

Physical Properties
C142 Grade has excellent corrosion resistance due to its high copper content, which acts as a barrier against oxidation. Its high ductility makes it resistant to cracking when exposed to temperatures up to 600 degrees Fahrenheit which makes it suitable for use in hot working processes such as forging or extrusion. In addition, Copper C142 maintains its strength even at temperatures up to 400 degrees Fahrenheit, making it suitable for use in higher temperature environments than some other alloys.
