You forgetting you need high temperatures to corrode steel

Have you ever seen a video of Jones/Harrit igniting one of their red/grey chips.
It's really really really really really really really really really really really really.......Unimpressive!
Notice how this dangerous explosive substance does absolutely nothing to the thin metal element it's sitting on.
How much of this would it take to burn through a 3" thick steel column?
Very unimpressive.
Wrong he observed Elemental Aluminimum separate from other components on the red/grey chips
www.abovetopsecret.com...
Using
a conventional quantification routine, it was found that the
aluminium significantly exceeded the oxygen present (approximately
a 3:1 ratio). Thus, while some of the aluminium
may be oxidized, there is insufficient oxygen present to account
for all of the aluminium; some of the aluminium must, therefore, exist in elemental form in the red material
Chemist Mark Basile who not involved with Harrit also found Iron and Aluminum in the sample he tested. He currently doing more work on this and will publish a paper or PDF on his findings when he has finished.

Now, can you point to actual video evidence to show there is any indication of CD by thermite?
The FEMA steel sample from WTC7 debunks everything you just said here.

The steel was hauled away to China and even the senators during a Senate hearing about 9/11 described it as a crime.

Results
The composition of the four samples of dust chosen for study were consistent with WTC dust previously published 2,3 (Appendix A).
Red/gray chips that had the same morphology and appearance as those reported by Harrit et al.1, and fitting the criteria of being attracted by a magnet and having the SEM-EDS x-ray elemental spectra described in their paper (Gray: Fe, Red: C,O, Al, Si, Fe) were found in the WTC dust from all four locations examined. The red layers were in the range of 15 to 30 micrometers thick. The gray layers were in the range of 10 to
50 micrometers thick (Appendix B).
The FTIR spectra of the red layer were consistent with reference spectra of an epoxy resin and kaolin clay (Figure 8) (Appendix C).
The SEM-EDS and backscattered electron (BE) analysis of the cross-sections of the gray layer in the red/gray chip showed it to be primarily iron consistent with a carbon steel. The cross-sections of the red layer showed the presence of equant-shaped particles of iron consistent with iron oxide pigment and plates of aluminum/silicon consistent with reference samples of kaolin. The thinnest kaolin plates were on the order of 6 nm with many sets of plates less than 1 micrometer thick. Small x-ray peaks of other elements were sometimes present. The particles were in a carbon-based matrix (Figures 9 through 14) (Appendix D).
TEM-SAED-EDS analysis of the residue after low temperature ashing showed equant-shaped particles of iron consistent with iron oxide pigment and plates of kaolin clay. Small numbers of titanium oxide particles consistent with titanium dioxide pigment were also found (Figure 15) (Appendix E).
PLM analysis of the residue from red/gray chips after muffle furnace ashing at 400oC for 1 hour showed very fine red particles consistent with synthetic hematite (iron oxide) pigment particles (Figure 16). PLM also found possible clay present based on a micro-chemical clay-stain test. TEM-SAED-EDS analysis of another portion of the same muffle furnace residue showed equant-shaped particles of iron consistent with iron oxide pigment, plates of kaolin clay and some aciniform aggregates of carbon soot consistent with incomplete ashing of a carbon-based binder (Figure 17). The SAED pattern of the kaolin particles (Figure 18) matched the kaolin pattern shown in the McCrone Particle Atlas8 (Appendix E). The values for the d-spacings determined for the diffraction patterns matched those produced by reference kaolin samples.
TEM-SAED-EDS analysis of a thin section of the red layer showed equant-shaped particles of iron consistent with iron oxide pigments and plates of kaolin clay (Figures 19 and 20). The matrix material of the red coating layer was carbon-based. Small numbers of titanium oxide particles consistent with titanium dioxide pigment and some calcium particles were also found (Appendix F).
The solvents had no effect on the gray iron/steel layer. Although the solvents softened the red layers on the chips, none of the solvents tested dissolved the epoxy resin and released the particles within. SEM-EDS phase mapping (using multivariate statistical analysis) of the red layer after exposure to MEK for 55 hours did not show evidence of individual aluminum particles (Appendix G).
In summary, red/gray chips with the same morphological characteristics, elemental spectra and magnetic attraction as those shown in Harrit et al.1 were found in WTC dust samples from four different locations than those examined by Harrit, et al.1 The gray side is consistent with carbon steel. The red side contains the elements: C, O, Al, Si, and Fe with small amounts of other elements such as Ti and Ca. Based on the infrared absorption (FTIR) data, the C/O matrix material is an epoxy resin. Based on the optical and electron microscopy data, the Fe/O particles are an iron oxide pigment consisting of crystalline grains in the 100-200 nm range and the Al/Si particles are kaolin clay plates that are less than a micrometer thick. There is no evidence of individual elemental aluminum particles detected by PLM, SEM-EDS, or TEM-SAED-EDS, during the analyses of the red layers in their original form or after sample preparation by ashing, thin sectioning or following MEK treatment.

Discussion
The Encyclopedia of Explosives9 describes thermite as essentially a mixture of powdered ferric oxide and powdered or granular aluminum. There are two sets of ingredients listed for thermite in Crippen’s book on explosives identification.10 The first is iron oxide and aluminum powder and the second is magnesium powder, ferric oxide, and aluminum powder. Nano-thermite (thermatic nanocomposite energetic material) has been studied in the Lawrence Livermore National Laboratory in California. A TEM image of a thin section of that material was published by R. Simpson11 in 2000 and
shows material that is made up of approximately 2 nanometer iron oxide particles and approximately 30 nanometer aluminum metal spheres (Figure 21).
According to the Federation of Societies for Coatings Technology, kaolin (also known as aluminum silicate or china clay) is a platy or lamellar pigment that is used extensively as a pigment in many segments of the paint industry.12 It is a natural mineral (kaolinite) which is found in vast beds in many parts of the world.13 Iron oxide pigments are also used extensively in paints and coatings.13,14 Both kaolin and iron oxide pigments have been used in paints and coatings for many years.13,14 Epoxy resins were introduced into coatings in approximately 194715 and are found in a number of specially designed protective coatings on metal substrates.
In forensic studies, paints and coatings often must be broken down so that the components of the entire coating product can be studied individually. Epoxy resins are formed from the reaction of two different chemicals which produces a polymer that is heavily cross-linked. Epoxy resins can be especially difficult to dissolve. Organic solvents, including those sold commercially for epoxy paint/coating stripping, were found to soften the red layer of the red/gray chips but did not dissolve the epoxy resin sufficiently so particles within the coating could be dispersed for direct examination. In this study no organic solvent was found to release particles from within the epoxy resin and it was necessary to use low temperature ashing to eliminate the epoxy resin matrix and extract the component parts of the coating. The other procedures generally used to examine component particles within a coating without extraction (cross-sections and thin sections) were also applied in this study.

conclusions
The red/gray chips found in the WTC dust at four sites in New York City are consistent with a carbon steel coated with an epoxy resin that contains primarily iron oxide and kaolin clay pigments.
There is no evidence of individual elemental aluminum particles of any size in the red/gray chips, therefore the red layer of the red/gray chips is
