CuCr1 C18200 2.1291 Copper Alloy Sheet Rod For Building Construction

This is because the resistivity to electron transport in metals at room temperature originates primarily from scattering of electrons on thermal vibrations of the lattice, which are relatively weak in a soft metal. The maximum permissible current density of copper in open air is approximately 3.1×106 A/m2 of cross-sectional area, above which it begins to heat excessively.

Copper Chromium is the primary copper alloy used for resistance spot and seam welding. This alloy achieves good hardness and electrical conductivity through a combination of heat treatment and cold work.

It is widely utilized for electrodes, holders, adaptors, as well as numerous electrical applications where resistance to deformation at high temperature is required or when higher mechanical properties than C11000 are required.
