Rezumat:

The values of the mechanic-electric characteristics of the special ecological quaternary alloys of type CuNiSiMn and CuNi4AlSi are placed at the inferior limit of the classic bronzes with beryllium. The values of the mechanic-elastic characteristics of the replacing alloys can be increased by mechanical hardening without influencing the value of the electric conductivity. The determination of the elasticity modulus E depending on temperature of the special ecological quaternary alloys has been performed using the non-conventional method of mechanic oscillations resonance. The present work studies the elasticity modulus E and the electric conductivity of the ecological quaternary alloys.
