Superplastic 5083 Aluminum Alloy Sheet “ALNOVI-1” was Approved by Airbus
have already participated in the A380 program for an
ultrahigh-capacity aircraft.
This is the first time that superplastic 5000 aluminum
alloys are applied for aircraft parts, and it is expected that
the demand expands during the course of strengthening
the cooperative relationship between Airbus S.A.S. and
Japanese corporations.

3. APPROVAL BY AIRBUS
In March 2002, the Fukaya Works of Furukawa-Sky
Aluminum underwent a preliminary inspection. The next
month, Airbus inspectors came from UK and examined
the factory and quality management system officially. In
June, we obtained the factory approval. We prepared
a quality management manual for material production,
and then acquired the material approval for “ALNOVI-1”
in May 2003. In November of the year, we press released
that “ALNOVI-1” was approved as a material for the
landing lamp drum assembly for Airbus A330/A340.
Recently, three Japanese corporations joined the
A300/A340 program, while fifteen Japanese corporations
