Zr Alloy

Cu-Ag-Zr alloy is a newly developed copper alloy material with an excellent combination of high mechanical strength and high electrical conductivity. Magnetic field was used in the solidification of Cu-Ag-Zr alloy. The results showed that with the application of magnetic field, formerly coarse columnar grain turned into homogeneous equiaxed grain. After aging, the precipitate of Zr had an increment and became more refined due to the reduction of segregation. The tensile strength and microhardness of Cu-0.1Ag-0.3Zr alloy under magnetic field of 15 mT increased by 17% and 10%, respectively. The electrical conductivity, with a slight decrease, was still as high as 92.4 %IACS.

Chain Ordering

Polyaniline is synthesized chemically under the influence of low magnetic field of intensity 1KGauss. The effect of magnetic field during the synthesis process causes enhancement of electrical conductivity by two orders of magnitude. This increased electrical conductivity depends on the polymer chain ordering, as well as structure and morphology of the reported polymer.

Copper Base Alloy

Abstract CDA C18700 is a copper-base alloy containing lead (nominally 1.0%). The lead is added to impart free-cutting properties to the metal. Although the lead lowers the electrical conductivity of CDA C18700 slightly below that of tough-pitch copper, it still has high electrical conductivity well within the limits needed for most current-carrying requirements. Typical uses comprise electrical motor and switch parts, electrical connectors and screw-machine parts requiring high conductivity. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-533. Producer or source: Copper and copper alloy mills.
