How dangerous is beryllium copper?
Toxicity. In solid form and as finished objects, beryllium copper presents no known health hazard. However, inhalation of dust, mist, or fume containing beryllium can cause the serious lung condition chronic beryllium disease, which restricts the exchange of oxygen between the lungs and the bloodstream.
What is chronic beryllium disease?
Chronic berylliosis, also known as chronic beryllium disease (CBD), is a progressive, systemic disease caused by an abnormally exaggerated immune response (delayed-type hypersensitivity reaction) in individuals who have become “sensitized” or allergic to beryllium (sensitizing antigen).
Is beryllium copper machinable?
Beryllium copper alloys are readily machinable. In chip making operations, a reduction of 10-25% in machining time, can be seen when compared to tool steels.
What color is beryllium copper?
This is silver coloured and has excellent tarnish resistance. Copper-beryllium CW100C (CB101). This alloy is used where very high yield strength is required (greater than 1000 N/mm2). These alloys are expensive and phosphor bronze will be adequate for most engineering applications.
What is the difference between copper and beryllium copper?
Copper is known as a soft metal, whereas BeCu is used for its strength. Beryllium copper has the highest strength rating of any copper-based alloy. Copper is mainly used for appearance, whereas BeCu is used for hardness and fatigue strength. Copper is 100% conductive, but beryllium copper ranges between 15-30%.
Is beryllium worth anything?
Beryllium scrap has a market value ranging from about $8 to$18 per pound, depending upon the nature of the scrap.
