Just nosing through the JSE and found this:

On Events Possibly Related to the ''Brazil Magnesium''
Kaufmann P.P.; Sturrock P.A.
Journal of Scientific Exploration, 1 June 2004, vol. 18, iss. 2, pp. 283-291

Abstract:
Inquiries in the Ubatuba area have yielded evidence of three aerial events that may be related to an unusual magnesium specimen, which is usually attributed to an event in or near Ubatuba, an analysis of which has been published in this journal. There is undisputed evidence that an aircraft crashed in that area in April 1957. There is strong evidence that a meteorite, or an object resembling a meteorite, crashed or exploded in the area in the early 1930's, and that a piece of strange light-weight material was caught in a fishing net at about that time. There is weaker evidence (mainly from one witness) that a very large object disintegrated, with a silent explosion, near Ubatuba in or about 1957. There is some evidence that, in or about 1957, one or more metal specimens were brought for analysis to an Air Force research center near Sao Paulo and found to be magnesium.

And here is the analysis mentioned above:

Composition Analysis of the Brazil Magnesium
Sturrock P. A.
Journal of Scientific Exploration, 1 March 2001, vol. 15, iss. 1, pp. 69-95

Abstract:
Some of the surviving fragments of the Brazil magnesium that purportedly had their origin in the explosion of a UFO have been subjected to surface, internal and isotopic analyses. The surface composition of four of the specimens has been determined to better than 1 part per million (ppm). There are some similarities, but also significant differences, so it is clear that the specimens were subjected to different influences. Some of the impurities (such as sodium and calcium) may be due to seawater or sand, but many of the impurities are incompatible with such contamination. Some of the impurities (titanium, chromium, iron, cobalt, selenium, strontium, yttrium, niobium, palladium and barium) may point toward an origin in a technological device or devices. Two specimens of Brazil magnesium, together with four comparison specimens, have been subjected to internal analysis by a laser ablation inductively coupled plasma mass spectrograph (ICP-MS) instrument. This analysis shows that the Brazil specimens contain calcium at a few thousand ppm and (as found by the Colorado Project) both strontium and barium at a few hundred ppm. One specimen also contains titanium at a few hundred ppm. This analysis indicates that the existing Brazil samples are not as pure as magnesium specimens readily available in the 1950s. Some of the specimens have been subjected to isotopic analysis. The only departures from normal isotopic ratios are small differences that may be attributed to fractionation as a result of heat treatment. The origin of these fragments remains a mystery. There is no evidence that the specimens are of extraterrestrial origin.

And a more general paper:

Physical Analyses in Ten Cases of Unexplained Aerial Objects with Material Samples
Vallee J. F.
Journal of Scientific Exploration, 1 September 1998, vol. 12, iss. 3, pp. 359-375

Abstract:
A survey of ten cases of unexplained aerial phenomena accompanied by material residues shows a broad distribution of natural elements, many of which are metallic in nature. They can be roughly described as belonging in two categories: ''light materials'' of high conductivity such as aluminum, and ''slag-like materials'' reminiscent of industrial byproducts. Most of the cases under consideration strive to meet four criteria: 1) the literature gives sufficient ground to support the fact that an unusual aerial phenomenon occurred, 2) the circumstances of the actual recovery of the specimen are reported, 3) there is data to suggest that the specimen is in fact linked to the observed aerial object, and 4) physical analysis has been performed by a competent laboratory of known reliability. In several instances the sample is available for continuing study by independent scientists. In the absence of a firm chain of evidence and of professional field investigation, most cases cannot lead to a definite conclusion about the nature of the phenomena that gave rise to each specimen, but much can be learned from the methodology involved in such analysis. Furthermore, compilation of similar cases on an expanded basis may eventually lead to the discovery of underlying patterns.

I actually saw a piece of this wreckage,
about 30 years ago at a UFO exhibit.

I looked at it carefully, and it reminded me of
a very old, exposed-to-the-elements piece of car tire.
Black and crumbly, but with an ash-like appearance
on the edges of some of the cracks. It wasn't possible
to touch it, but it really looked like a chunk of
weathered rubber.

I'm not sure if the description in the exhibit
mentioned the high magnesium content,
or if I read that part later on...

FWIW...

This thread begins in the middle of the storyline, so it's a bit confusing at face value. The story begins on 14 September 1957, when a Brazilian journalist received an anonymous letter and some mystery metal fragments ...

Here are some online references providing both background to the metal analysis described above and follow-up information on what happened later.
