FIELD: metallurgy.

SUBSTANCE: invention relates to material for cables based on aluminium alloy and to a method for its obtaining. Aluminium-based alloy contains the following, wt %: 0.3-1.2 Fe, 0.03-0.10 Si, 0.01-0.30 rare-earth elements Ce and La, inevitable impurities - less than 0.3 and aluminium is the rest; content of Ca in impurities is 0.02%, and content of any other impurity element - 0.01%. An alloy obtaining method involves preparation of a melt by melting of 92-98 weight parts of aluminium melt containing 0.07-0.12% Si and 0.12-0.13% Fe, and 0.73-5.26 weight parts of Al-Fe melt with content of Fe of 20-24%, heating of melt to 720-760°C, addition of 1-3 weight parts of Al alloy - 9-11% rare-earth elements Ce and La and 0.17-0.67 weight parts of Al alloy - 3-4% B, addition of 0.04-0.06 weight parts of a refining agent and refining during 8-20 minutes, exposure at the temperature during 20-40 minutes, casting and further semi-annealing at the temperature of 280-380°C during 4-10 hours with natural cooldown to ambient temperature.

EFFECT: conductor made from aluminium alloy has a high degree of elongation and has good safety and stability at application.
