| 简介 |
FIELD : metallurgy.SUBSTANCE : invention refers to metallurgy, particularly to aluminium alloys designed for implementation as structure material in machine building, aircraft building, rocket production, shipbuilding, automobile industry and also in medical equipment, engineering, building, electrical engineering and in domestic equipment. Aluminium alloy contains following components, wt % : at least one rare earth metal 5.0-10.0, oxygen 0.002-1.5, nitrogen 0.002-1.2, hydrogen 0.0002-0.5, aluminium - the rest. In a particular case of implementation of the invention aluminium additionally contains at least one element selected out of group : silicon, copper, magnesium, chromium, zirconium, boron, manganese, zinc, nickel, yttrium, scandium, titanium, vanadium, molybdenum, niobium, tantalum, or iron at amount of 0.005-2.2 wt %. There is produced alloy possessing upgraded electro-conductivity, weldability and stable mechanical characteristics at temperatures up to 350°C.EFFECT : production of alloy possessing upgraded electro-conductivity, weldability and stable mechanical characteristics.2 cl, 6 ex |
