Effect of Tellurium on Brass

The presence of small amounts of tellurium in certain kinds of copper, and its exceptionally deleterious influence in producing red-shortness of this metal, led the author to conduct a few experiments on the influence of tellurium on the properties of brass. While these experiments were not intended to be exhaustive, they demonstrate that, as far as the rolling of brass is concerned, tellurium ...
