Considering combined factors of cost, conductivity, tensile strength, weight etc., aluminum has an edge over copper. Therefore, aluminum is being widely used for overhead conductors. Cadmium-copper: Cadmium-copper alloys contain approximately 98 to 99% of copper and up to 1.5% of cadmium. Addition of about 1% of cadmium to copper increases the tensile strength by up to 50% and the conductivity is reduced only by about 15%.

Temper" describes the strength and hardness of the tube. In the piping trades, drawn temper tube is often referred to as "hard" tube and annealed as "soft" 

Soft copper is hard drawn copper that has been heated and annealed. Soft copper has an ultimate Tensile strength of about 32000psi .Hard drawn copper Tensile strength can vary from about 45000psi to 55000psi. Hard wire is stiffer and generally not suitable for wiring except in Continue Reading More answers below Quora User
