CuFe1P
EN: -
UNS: C19200, C19210
MANUFACTURERS LIST

CuFe1P has a nominal copper content of 99.9%, CuFe1P has small amount of iron and phosphorus in chemical compositions, and is hardened by Fe2P precipitates in copper matrix. It is heat-treat hardenable copper alloys. High performance copper alloy with relatively high strength and electrical conductivity Its electrical conductivity is 80% IACS 20°C and it has good heat resistant characteristics. It has good hot forgeability and good capacity for being cold work. Its workability characteristics are good and it can be fabricated by a wide range of processes. It can be machined successfully and joined by a number of methods. This alloy has good resistance to softening and to stress corrosion cracking. In many environments its corrosion resistance is similar to that of copper.

CuFe1P has higher stengths than many alloys found on the market today. CuFe1P retains much of the formability and conductivity that is often lost on the other copper alloys. This enables  purchase a material that is superior in strength; allowing higher contact forces.

Exploitation properties

The cast CuFe1P were hot rolled into bars of 22mm diameter and solution treated for 70min at 900 ?C in a furnace full of nitrogen atmosphere. followed by water quenching. These solution treated bars were cold rolled by about 50% into rods. Then the rods were machined into tensile samples of 10mm diameter and cut into conductivity test samples 2 mm in diameter and 200mm in length
