Magnesium transport properties

Caution. Transition metal carbonyl derivatives of magnesium are pyrophoric and must be handled with extreme care (see Properties). The toxicity of the magnesium derivatives is not known but is probably of the same magnitude as the parent carbonyls. The magnesium-transition metal-carbonyl complexes exhibit low vapor pressures and therefore do not present a vapor-transport toxicity problem when an inert-atmosphere enclosure is employed. 

The Al-6Cu-Mn alloy differs from other aluminum alloys in that it has relatively good mechanical properties at low temperatures and, therefore, can be successfully used for low-temperature structures. Unlike the duralumin-type alloys, the Al-6Cu-Mn heat-treatable alloy contains more copper (5.8 to 6.8%) and no magnesium [ ]. It is similar to the USA alloy 2219. It has satisfactory weldability and mechanical properties over a wide range of temperatures from 20 K up to 523 K, making it suitable for welded vessels for liquefied gas transportation and storage. 

Red phosphorus flame-retardants are effective in thermoset resin systems and also elastomers, often combined with ATH, or magnesium hydroxide in elastomers. A wide range of treated red phosphorus in dispersion or concentrate form, offered by Clariant, is easier to handle and safer to transport, compared with powder grades. Such phosphorus additives do not affect the electrical properties of the composite, and they have little impact on the physical properties of the laminates manufactured.
