Adjustable Wrench with 'BeCu' on the side, to show that it is made from beryllium copper. Beryllium copper (BeCu), also known as copper beryllium (CuBe), beryllium bronze, and spring copper, is a copper alloy with 0.5–3% beryllium. [1] Copper beryllium alloys are often used because of their high strength and good conductivity of both heat and ...
The signs and symptoms of acute beryllium pneumonitis usually resolve over several weeks to months, but may be fatal in 10 percent of cases, [1] and about 15–20% of cases may progress to chronic beryllium disease. [8] Acute beryllium poisoning approximately doubles the risk of lung cancer. [9]
Beryllium poisoning is poisoning by the toxic effects of beryllium, or more usually its compounds. It takes two forms: Acute beryllium poisoning, usually as a result of exposure to soluble beryllium salts; Chronic beryllium disease (CBD) or berylliosis, usually as a result of long-term exposure to beryllium oxide usually caused by inhalation.
Relevant occupations are those where beryllium is mined, processed or converted into metal alloys, or where machining of metals containing beryllium and recycling of scrap alloys occurs. [21] It is associated with aerospace manufacturing, microwave semiconductor electronics, beryllium mining or manufacturing of fluorescent light bulbs (which ...
Sep. 27—Eight electrical workers recently were exposed to toxic beryllium dust while removing ceiling tiles in a building at Los Alamos National Laboratory, the latest incident in a hazard the ...
The river water was contaminated with toxic metals including arsenic, copper, barium, cadmium, chromium, lead, mercury, nickel, and thallium. [2] Cleanup costs may exceed $1.2 billion. [3] A toxic heavy metal is a common but misleading term for a metal-like element noted for its potential toxicity. [4]
Various examples of metal swarf, including a block of compressed swarf. Broken up chips are preferred over stringy drill chips. [1]Metal swarf, also known as chips or by other process-specific names (such as turnings, filings, or shavings), are pieces of metal that are the debris or waste resulting from machining or similar subtractive (material-removing) manufacturing processes.
Some industries require the electrical or thermal conductivity of beryllium copper in areas such as aerospace, electrical, and the defense industry, or the high strength application of steel and its many alloys for the automotive industry. Industries metal stamping is used for: Aerospace; Agriculture; Ammunition; Major appliances; Small ...
