What is C17200?
C17200 is also known as Alloy 25 and is the most commonly utilized beryllium copper alloy and is notable for exhibiting the highest strength and hardness compared to commercial copper alloys. Its strength and hardness is similar to that of steel.
What is alloy 25?
Alloy 25 is a versatile material that provides the highest strength of any copper beryllium alloy, with electrical and thermal conductivity considerably greater than other high-strength copper alloys.
What is beryllium wire used for?
Beryllium is non-magnetic, is a good thermal conductor and is used as an alloying addition to copper or nickel, the alloys having excellent thermal, mechanical and electrical properties; in addition, when alloyed with nickel, the resultant Be/Ni alloy has the highest coefficient for secondary electron emission (12.3).
Is beryllium copper toxic?
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 ASTM B16?
ASTM B16 Applications Farmers Copper’s ASTM B16 free-cutting brass is utilized in high machining applications that require turning, drilling, and milling because of its machinability. This type of brass alloy is used for valve parts, faucet components, fasteners, plumbing fittings, and more.
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%.
What is beryllium copper worth?
The Platts Metals Week published prices for selected beryllium products were as follows: BCMA, $160 per pound of contained beryllium; beryllium copper alloy strip, $9.95 per pound; and beryllium copper casting ingot $6.40 per pound.
Is beryllium stronger than steel?
Beryllium. Beryllium is six times stronger than steel and more than 30% lighter than aluminum.
Is it safe to touch beryllium?
Direct contact with beryllium fumes or dusts may injure the exposed areas of the body, such as the eyes or the skin. Skin sensitization may also occur. Beryllium is also a known cancer causing substance, with higher levels of lung cancer being reported.
Is beryllium copper safe to touch?
Does routine touching or handling of copper beryllium alloy products in solid or massive form cause skin reactions or rash? No, routine contact with copper beryllium alloys does not generally cause skin reactions or rash. Prolonged contact with beryllium metal has not been shown to result in a skin reaction.
What is ASTM B62?
ASTM B62, 2017 Edition, April 1, 2017 – Standard Specification for Composition Bronze or Ounce Metal Castings. This specification2 establishes requirements for an alloy having a composition of copper, tin, lead, and zinc, used for component castings of valves, flanges, and fittings.
