Lightweight metals

Pigmented resins are applied as dry powders and then fused by heating to 220°C or higher. The process is effective with lightweight metal components and pipework. It is likely to remain uneconomic for use on heavy sections, e.g. hot-rolled steel universal beams and columns. 

Element x is a lightweight metal through which x rays pass easily. 

The combination of toxic hazard and high price (itself in part due to the extra measures needed in production processes to ensure the workers safety) has been an effective brake on commercial development of beryllium chemistry. Where possible substitute, albeit less effective, materials are often used titanium as an alternate lightweight metal or carbon fiber composites, phosphor-bronzes in place of beryllium alloys, aluminum nitride in place of BeO (1).

Historical Development of Lightweight Metal Hydrides and Hydride Complexes... 

The material science challenge is to understand better the electronic behavior of the interaction of hydrogen with other elements, especially metals. Complex compounds such as A1(BH4)3 have to be investigated and new compounds formed from lightweight metals and hydrogen will be discovered. 

Lightweight metal with anticorrosive properties combines with iron and aluminum to form metal alloys useful in manufacturing. 

Fan blades. These are fabricated of lightweight metal or plastics and are balanced. 

The transition metals iron and copper have been known since antiquity and have played an important role in the development of civilization. Iron, the main constituent of steel, is still important as a structural material. Worldwide production of steel amounts to some 800 million tons per year. In newer technologies, other transition elements are useful. For example, the strong, lightweight metal titanium is a major component in modern jet aircraft. Transition metals are also used as heterogeneous catalysts in automobile catalytic converters and in the industrial synthesis of essential chemicals such as sulfuric acid, nitric acid, and ammonia. 

Aluminum is an element and is one of the most abundant metals on Earth. This soft, lightweight metal is often used in packaging to make beverage containers and foil. Recycling of aluminum is... 

During the 1800s, chemists discovered about half of the 100 known elements. After 1850, organic chemicals, such as coal-tar dyes, drugs, nitroglycerin explosives, and celluloid pieties, were developed and manufactured. The two world wars created needs for new and improved chemical processes for munitions, fiber, lightweight metals, synthetic... 

Bromine is one of the two elements that are liquids at room temperature. Mercury is the other. Aluminum is a lightweight metal that resists corrosion. Aluminum and bromine react vigorously to form the ionic compound aluminum bromide. 

Recently, metal-doped aluminium hydrides have been proposed as further potential hydrogen storage materials [107, 123]. Among lightweight metal hydrides the lithium and sodium alanates (NaAfflU, LiAlH4) have been widely...

Aluminum is a lightweight metal (density = 2.70 g/cm ) used in aircraft construction, high-voltage transmission lines, beverage cans, and foils. What is its density in kg/m ... 

Lithium extraction takes place mainly in North and South America from rocks and brines associated with volcanic activity and aridity. Most of the world s lithium is used in the production of lightweight metal alloys, glass, lubrication greases, and electrical batteries. Only a small proportion of lithium production (less than 1% of the total) is used in medicine. 

Thin films of lightweight metals (e.g. alanates) will soon be investigated optically. 

Lithium and other metals alloyed to aluminium, zinc, or manganese to produce lightweight metals for many uses. 

Titanium (Ti) is a strong, lightweight metal that is used in the construction of rockets, jet engines, and bicycles. It can be prepared by reacting TiCU with Mg metal at very high temperatures. The products are Ti(s) and MgCh. 

Because pure aluminum is soft and has a relatively small tensile strength, it is alloyed with other metals to make it stronger, easier to weld, and to increase its resistance to corrosive environments. Lightweight metals, such as alloyed aluminum, are used in many structural and aerospace applications because of their small densities (relative to steel) and high strength-to-weight ratios. 

Aluminum, titanium, and magnesium, because of thdr small densities (relative to steel), are commonly relmed to as U Jtweight metals. Because of their relatively higji strei th- o-weight ratios, lightweight metals are used in many structural and aerospace applications.
