Aluminium alloys
Aluminium alloys and technologies of their industrial production developed by
CRISM "Prometey" are successfully used in many industries:
shipbuilding, machine building, etc.
As aluminium alloys used for sea-going ships shall have high corrosion
resistance and good weldability the aircraft-grade aluminum developed
specially for riveted (not welded) aircraft structures with low corrosion
resistance in sea water was not suited to shipbuilding. Institute developed
aluminum-magnesium alloys of new class with high corrosion resistance in sea
water and good weldability using all types of welding. To increase strength
and corrosion characteristics of weld joints from these alloys no additional
heat treatment is required – their strength and corrosion resistance
practically do not differ from similar properties of initial material.
