For example, for both spot and seam types of welding electrodes. Strip, and, to a lesser extent, wire are used for light springs destined to carry current. Commutator segments that are required to operate at temperatures above those normally encountered in rotating machines are another application. In its heat-treated state, the material can be used at temperatures up to about 350◦ C without risk of deterioration of properties. 30 In the solution heat-treated condition chromium copper is soft and can be machined.

The steels have a crystalline structure and the magnetic properties of the sheet are derived from the magnetic properties of the individual crystals or grains. The grains themselves are anisotropic. That is, their properties differ according to the direction along the crystal that these are measured. Until the 1940s the sheet steels were produced by a process of hot-rolling in which the grains are packed together in a random way so that the magnetic properties of the sheet have similar values regardless of the direction in which they are measured.

In terms of line voltage VL and line current IL the power equation becomes 3 √ VL IL cos φ 2 In both cases cos φ is the phase angle between the phase voltage and phase current. Three-phase 4-wire. 16 ) is now used almost universally in the UK for 400 V distribution. There are three ‘lines’ and a neutral. The voltage between any one √ ‘line’ and neutral is nominally 230 V and voltage between the ‘lines’ is 3 times the voltage to neutral. This gives a three-phase voltage of 400 V for motors, etc.
