Abstract Rio Tinto Alloy 242.2 is a heat-treatable, aluminum-copper-magnesium-nickel casting alloy. It is available in the form of ingots to be remelted for the manufacture of sand and permanent mold castings. Alloy 242.0 is used extensively for applications requiring high strength and hardness at elevated temperatures. This datasheet provides information on composition, physical properties, elasticity, tensile properties, and shear strength as well as fatigue. It also includes information on corrosion resistance as well as casting, machining, and joining. Filing Code: Al-463. Producer or source: Rio Tinto Limited.

Tungsten Mineralization

K–Ar dating of magmatic biotite, and of hydrothermal biotite and muscovite, demonstrates that quartz monzonite intrusion and exoskarn scheelite mineralization at Cantung, N.W.T., took place over a brief interval in the Upper Cretaceous (ca. 91 Ma). The regional age relationships of magmatic and ore-forming activity in the Logan–Mackenzie Mountains are poorly defined, but it is tentatively inferred that tungsten mineralization may have been related to a late stage in the plutonic development of the area.

Objetivou-se, com esta pesquisa, analisar a qualidade do tratamento preservativo da madeira juvenil de Eucalyptus camaldulensis Dehnh. e verificar a influência da inversão das peças na solução preservativa, na distribuição, na penetração e na retenção do CCB, ao longo das peças tratadas pelo método de substituição de seiva. Árvores de Eucalyptus camaldulensis foram coletadas na Zona Rural do Município de Rio Tinto - PB, de um povoamento com quatro anos. No povoamento foram escolhidas, aleatoriamente, cinco árvores, sendo três de maior diâmetro. Para o tratamento da madeira, empregou-se o método de substituição de seiva por transpiração radial utilizando-se uma solução de 2% de ingredientes ativos de borato de cobre cromatado (CCB) e comparou-se o efeito da inversão das peças na solução preservativa. A distribuição, a penetração e a retenção foram melhores nas peças invertidas, quando comparadas àquelas não-invertidas na solução preservativa.

The great pyrites masses of the Sierra Morena, of which those worked at Rio Tinto are by far the most extensive, may be briefly described as contact deposits, which differ from such as are ordinarily met with only in size; and from ordinary fissure veins only in the circumstance that the cavities in which the minerals occur are bounded by dissimilar rocks.
