Moist ammonia attacks copper, tin, zinc and their alloys. Ammonia is also flammable with flammability limits of 15-28%. 

Other alloys Other copper alloys can be plated, including copper-tin-zinc (Alballoy) , copper-nickel , copper-cadmium , copper-gold and copper-lead . 

Prior to the Civil War, engineers were pretty well limited to working with only a few materials, such as iron, copper, tin, zinc, brass and bronze and, of course, wood. Steel became more readily available shortly after the Civil War through the wider use of the recently discovered Bessemer and open-hearth processes and the subsequent discovery of alloy steels. And around the turn of the century, aluminum was becoming available in commercial quantities. 

Beer may contain injurious metals, such as lead, copper, tin, zinc and iron (which imparts to the beer an unpleasant taste), derived from the vessels and plant used in its manufacture or from impurities of the raw materials in some cases arsenic has been found, this occurring as an impurity in the glucose used. 

Alloys.—Phosphorus as a constituent of bronzes is chiefly valued for its deoxidising effect, which confers a great toughness on the metal. The principal alloys are those containing copper, tin, zinc, nickel, lead and antimony. The phosphorus is usually added in the form of phosphor-tin. Phosphor-coppers may be made by heating copper phosphate or copper turnings and phosphorus in crucibles at 600-800°. 8 Phosphor-bronze may contain Cu 89, Sn 11 and P 0-3 per cent.8 The phosphorus should not exceed 0-6 per cent. 

Politecnico di Milano and Ineos Vinyls UK developed a tubular fixed bed reactor comprising a metallic monolith 67,130). The walls were coated with catalytically achve material, and the monolith pieces were loaded lengthwise. Coming, the world leader in ceramic structured supports, developed metallic supports with straight channels, zigzag channels, and wall-flow channels. These metallic supports were produced by extrusion of metal powders, for example, copper, tin, zinc, aluminum, iron, silver, nickel, and mixtures and alloys (131). An alternative method is extmsion of softened bulk metal feed, for example, aluminum, copper, and alloys thereof. The metal surface can be covered with coating such as carbon, carbides, and alumina, for example, by application of a CVD technique (132). 

The presence of some metals like copper, tin, zinc, aluminium, iron and lead only slightly influences the velocity of decomposition even at boiling point. ... 

Because the heavier elements are formed in localized areas of the universe, the distribution of these elements is uneven. The elemental composition of the earth, for example, is very different from most of the rest of the universe. Table 18.5 lists the percent abundance of elements in the earths crust, waters, and atmosphere. Note that eleven elements make up over 99% of the planets mass. Some elements that play major roles in our culture and technology—such as copper, tin, zinc and gold—are actually very rare. 

AI3-15639 (75-50-3) Extremely flammable liquefied gas [flash point 20°F/-6°C (25% solution in H2O) 41°F/5°C]. A medium-strong organic base.
