                        AMENDMENT NO. 25 TO SCHEDULE 13D

     This amended  statement on Schedule 13D  (collectively,  this  "Statement")
relates  to the  common  stock,  $0.01 par value per share  (the  "Shares"),  of
Titanium  Metals  Corporation,  a Delaware  corporation  (the  "Company").  This
amendment  is filed as result  of an  increase  in the  outstanding  Shares,  as
reported  by the  Company on its  Annual  Report on Form 10-K for the year ended
December 31, 2005 and filed with the U.S.  Securities and Exchange Commission on
March 24, 2006 (the "2005 Form 10-K"). The outstanding Shares as reported in the
2005 Form 10-K indicated a decrease in the aggregate holdings of the Shares held
by the persons filing this Statement by more than one percent of the outstanding
Shares.  Items 2, 4, 5 and 6 of this  Statement are hereby  amended as set forth
below.

     All Share amounts in this  amendment no. 25 to this  Statement  reflect the
two-for-one  split of the Shares  that the  Company  paid in the form of a stock
dividend on the close of  business on February  16, 2006 to holders of record as
of the close of business on February 6, 2006 (the "Stock Split").

according to  information  provided by the Company (the  "Outstanding  Shares").
Tremont LLC may be deemed to control the Company.

     Valhi also directly  holds 14,700  shares of Series A Preferred  Stock that

Shares  assuming  the full  conversion  of only the shares of Series A Preferred

Preferred Stock that are convertible  into 10,666,666  Shares,  or approximately
12.4% of the outstanding  Shares assuming the full conversion of only the shares
of Series A Preferred Stock she directly holds.

     Valhi is the direct holder of 100% of the outstanding  membership interests
of Tremont LLC and may be deemed to control  Tremont LLC.  VHC, the  Foundation,

common stock. The Foundation is a tax-exempt foundation organized for charitable
purposes.  Harold C. Simmons is the chairman of the board of the  Foundation and

     The CDCT No. 2 directly holds  approximately  0.4% of the outstanding Valhi

obligations,  Contran is obligated to satisfy the balance of such obligations as
they come due.  Pursuant to the terms of the CDCT No. 2, Contran (i) retains the
power to vote the shares of Valhi common stock held  directly by the CDCT No. 2,
(ii)  retains  dispositive  power  over such  shares and (iii) may be deemed the
indirect beneficial owner of such shares.

     NL Industries,  Inc.  ("NL") and a subsidiary of NL directly hold 3,522,967
shares and 1,186,200 shares,  respectively,  of Valhi common stock.  Valhi and a

0.5%,  respectively,  of the outstanding  shares of NL common stock and together

     Mr. Harold C. Simmons is chairman of the board and chief executive  officer
of NL and chairman of the board of the Company,  Tremont LLC,  Valhi,  VHC, VGI,

entities described above and (b) Mr. Simmons and certain of such entities may be
deemed to possess  indirect  beneficial  ownership  of Shares  directly  held by
certain of such other  entities.  Mr. and Ms. Simmons each disclaims  beneficial
ownership of the Shares  beneficially owned,  directly or indirectly,  by any of
such entities.

     Annette C. Simmons is the direct holder of 228,000 Shares, 1,600,000 shares
of Series A Preferred Stock and 43,400 shares of Valhi common stock. Mr. Simmons
may be deemed to share indirect beneficial ownership of such shares. Mr. Simmons
disclaims all such beneficial ownership.

     Harold C. Simmons is the direct owner of 1,933,700  Shares and 3,383 shares

disclaims  beneficial  ownership of all Shares that her husband may beneficially
own.

     A trust of which Harold C.  Simmons and Annette C. Simmons are  co-trustees

direct  holder  of 36,500  shares of Valhi  common  stock.  Each of Mr.  and Ms.
Simmons disclaims beneficial ownership of these shares.

     Certain information  concerning the directors and executive officers of the
Reporting  Persons,  including  offices  held by Mr.  Simmons  is set  forth  on
Schedule B attached hereto and incorporated herein by reference.

     The Reporting  Persons  understand  that the funds  required by each person
named in Schedule B to this  Statement to acquire Shares were from such person's
personal funds.

Item 4.  Purpose of Transaction

     Effective as of the close of business on January 13, 2006,  Contran,  Valhi
and  the  CMRT  executed  a  written  consent  of at  least  a  majority  of the
Outstanding Shares to approve an amendment to the Company's amended and restated
certificate of  incorporation  to increase the number of authorized  Shares from
90.0 million to 200.0 million (the  "Amendment").  The written consent procedure
(including the  distribution  of an Information  Statement to all holders of the
Outstanding  Shares)  allowed the Company to avoid the costs and management time
involved  in  holding  a  special  meeting  of  its  stockholders.  The  Company
subsequently  filed the  Amendment  with the  Secretary of State of the state of
Delaware on February 15, 2006 and paid the stock  dividend  effecting  the Stock
Split on February 16, 2006.

     In addition to the Stock Split,  the  increase in the number of  authorized
Shares enables the Company to effect its business strategy,  provide flexibility
and provide  sufficient  authorized  Shares to be reserved for issuance upon the
exercise of outstanding stock options and the full conversion into Shares of the
Company's  convertible  preferred  securities,  as such  conversion  rights  are
adjusted to reflect the Stock Split.

     The authorized Shares in excess of outstanding Shares will be available for
issuance at such times and for such general corporate  purposes as the Company's
board of directors  may deem  advisable.  Any such  issuances  may occur without
further  action by the  Company's  stockholders,  except as may be  required  by
applicable  law or by the rules of the New York Stock  Exchange,  Inc., on which
the Shares are listed for trading. Upon issuance,  any such Shares will have the
same rights as the  outstanding  Shares.  Holders of Shares  have no  preemptive
rights. The issuance of additional Shares may have a dilutive effect on earnings
per share and on a stockholder's  percentage voting power for persons who do not
purchase additional Shares to maintain their pro rata interest.

     None of the  Reporting  Persons  has  made  any  arrangements,  agreements,
understandings  or plans at the  present  time for the  issuance  or use of such
additional  Shares  proposed to be  authorized,  other than the Company's use of
such  Shares in  connection  with the Stock Split and the  possible  exercise of
outstanding  stock  options and the  conversion of the  outstanding  convertible
preferred securities of the Company. Additionally, the Reporting Persons have no
present  intention  to cause the issuance of such  additional  Shares that would
make the  acquisition of control of the Company by unrelated  third parties more
difficult.

     Depending  upon their  evaluation of the Company's  business and prospects,
and upon future developments (including,  but not limited to, performance of the
Company's securities in the market,  availability of funds,  alternative uses of
funds,  the Reporting  Persons' tax planning  objectives  and cash needs,  stock
market and general economic  conditions),  any of the Reporting Persons or other
entities or persons  that may be deemed to be  affiliated  with Contran may from
time to time purchase Company  securities,  and any of the Reporting Persons, or
other  entities or persons that may be deemed to be affiliated  with Contran may
from time to time dispose of all or a portion of Company securities held by such
entity or  person,  or cease  buying or  selling  Company  securities.  Any such
