      Allegheny Technologies Announces Phase III Expansion of its Titanium
                                  Capabilities

    PITTSBURGH--(BUSINESS WIRE)--June 22, 2006--Allegheny Technologies
Incorporated (NYSE:ATI) announced today a further expansion of its
titanium sponge facility and melt capabilities in Albany, OR. This
investment is aimed at increasing ATI's capacity to produce titanium
and titanium alloys for aerospace and defense applications and for
other robust global markets, such as medical, oil and gas,
desalination, electrical energy, and marine transportation.

    The $25 million Phase III expansion includes:

    --  Additional titanium sponge capacity. ATI expects to add
        another 4 million pounds of titanium sponge to its annual
        production capabilities beginning in the third quarter 2007.
        In combination with the Phase I and Phase II sponge
        investments, this brings the Albany, OR annual sponge capacity
        to approximately 16 million pounds. Titanium sponge is a
        critical raw material used to produce titanium mill products.

    --  Additional vacuum arc remelt (VAR) capacity. ATI expects this
        new furnace to be in production by the end of 2007. Titanium
        sponge, combined with titanium scrap and master alloy, is
        melted in a VAR to produce a titanium alloy ingot.

    "We expect attractive after-tax returns from the Phase III
expansion of our titanium production capabilities when fully
implemented in the third quarter 2007," said Patrick Hassey, Chairman,
President and Chief Executive Officer of Allegheny Technologies.
"These investments are a continuation of ATI's strategy to grow our
titanium products capabilities.
    "ATI is uniquely positioned to profitably grow quickly and
efficiently in the global titanium market. We are adding to our
titanium raw material supply and our unequaled melt capabilities. In
addition, we have an unparalleled combination of assets for finishing
titanium products."
    ATI previously announced two phases of its titanium products
expansion, now expected to yield approximately 12 million pounds of
titanium sponge and a significant increase in titanium melting
capacity:
    1. Phase I expansion of ATI's titanium production capabilities was
announced on July 15, 2005, and includes: upgrading and restarting
ATI's titanium sponge facility in Albany, OR, constructing a third
Plasma Arc Melt (PAM) cold-hearth furnace in Bakers, NC, expanding
high-value plate products capacity by 25%, and continued upgrading of
ATI's cold-rolling assets used in producing titanium sheet and strip
products.
    2. Phase II expansion of ATI's titanium production capabilities
was announced on March 17, 2006, and includes: additional titanium
sponge capacity at ATI's facility in Albany, OR, and constructing an
additional vacuum arc remelt furnace (VAR) in Bakers, NC.
    ATI now targets a total of $250 - $275 million of capital
investments in 2006 in a self-funded growth strategy.
