Allegheny Technologies Announces Phase II Expansion of its Titanium Capabilities

    PITTSBURGH--(BUSINESS WIRE)--March 17, 2006--Allegheny
Technologies Incorporated (NYSE:ATI) announced today the Phase II
expansion of its titanium production capabilities. These investments,
which total approximately $25 million, are aimed at increasing ATI's
capacity to produce titanium and titanium alloys for aerospace
applications and other robust global markets.
    The Phase II expansion includes:

    --  Additional titanium sponge capacity. ATI expects to add 3.75
        million pounds of titanium sponge to its annual production
        capabilities beginning in the first half 2007. In combination
        with the Phase I sponge investment, this brings ATI's total
        annual sponge capacity to approximately 11.25 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 the first
        quarter 2007. Titanium sponge, combined with titanium scrap
        and master alloy, is melted in a VAR to produce a titanium
        alloy ingot.

    "We expect an additional $100 million of annual revenue growth
with attractive after-tax returns from the Phase II expansion of our
titanium production capabilities when fully implemented in the second
quarter 2007," said Patrick Hassey, Chairman, President and Chief
Executive Officer of Allegheny Technologies. "These titanium
investments are a continuation of ATI's strategy to grow our
high-value products capabilities.
    "We believe ATI's long-term growth prospects for titanium mill
products remain very attractive. We continue to evaluate further
options for additional organic growth of ATI's titanium sponge and
melting capabilities. ATI has an unparalleled combination of assets
for finishing titanium products, and we believe we are uniquely
positioned to grow fast in the global titanium market."
    Phase I expansion of ATI's titanium production capabilities was
announced on July 15, 2005, and is expected to generate more than $200
million in new revenue when fully implemented in 2007. The Phase I
expansion represents a $100 million strategic capital investment that
includes: upgrading and restarting ATI's titanium sponge facility,
constructing a third plasma arc melt cold-hearth furnace, 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.
    ATI now targets a total of $225 - $250 million of capital
investments in 2006 in a self-funded growth strategy.
