High-copper alloys

Table 8. Properties of Copper and High Copper Alloys...

The specimens should be mounted so that they are insulated from their supporting racks and from each other. Such insulation can be achieved by the use of fastening assemblies, such as illustrated in Fig. 19.33. Occasional difficulties have been encountered with this sort of assembly for tests of copper and high-copper alloys because of deposition of copper from corrosion products along the surfaces of the insulating tubes which provided a... 

There is a danger of explosion in contact with copper, high-copper alloys, mercury or silver (arising from metal acetylide formation).

Although AI protects itself against corrosion by forming a natural oxide, the protection is not complete. In the presence of moisture and electrolytes, AI alloys, particularly the high-copper alloys, corrode much more rapidly than pure Al. 

Although not meeting the foregoing definition of copper precisely, there is a group of copper alloys which contain only a few percent <>r other ingredients and commonly these are also referred lo as coppers, usually with the name of the other element preceding copper in the name—as chromium copper or beryllium copper. These vcry-high-copper alloys are described briefly in Table 2. 

BIETHYLENE (106-99-0) QH Extremely flammable, polymerizable gas extremely low ignition temperature makes it very dangerous [explosion limits in air (vol %) 2.0 to 11.5 flash point -105°F/-76°C autoignition temp 788°F/420°Ct Fire Rating 4]. Self-reactive. In absence of an inhibitor (e.g., ferf-butyl catechol), autoxidation forms heat-, mechanical shock-, and impact-sensitive peroxides with air. Fires, explosions, or hazardous polymerization may result from contact with strong oxidizers, aliuninumtetrahydroborate, copper, high copper alloys, chlorine dioxide.
