Monocryl has a low tissue reactivity, maintains high tensile strength, and has a half-life of 7 to 14 days. At 1 week, its in vivo tensile strength is at 50–60% undyed (60–70% dyed), 20–30% undyed (30–40% dyed) at two weeks, and essentially completely hydrolyzed by 91–119 days. [ 3 ]
Very importantly, constantan can be processed for self-temperature compensation to match a wide range of test material coefficients of thermal expansion.A-alloy is supplied in self-temperature-compensation (S-T-C) numbers 00, 03, 05, 06, 09, 13, 15, 18, 30, 40, and 50, for use on test materials with corresponding thermal expansion coefficients, expressed in parts per million by length (or μm ...
Monel was used for much of the exposed metal used in the interior of the Bryn Athyn Cathedral in Pennsylvania, religious seat of the General Church of the New Jerusalem. This included large decorative screens, doorknobs, etc. [ 1 ] Monel also has been used as roofing material in buildings such as the original Pennsylvania Station in New York City.
ZAMAK (or Zamac, formerly trademarked as MAZAK [1]) is an eclectic family of alloys with a base metal of zinc and alloying elements of aluminium, magnesium, and copper. Zamak alloys are part of the zinc aluminium alloy family; they are distinguished from the other ZA alloys because of their constant 4% aluminium composition.
The first 3 digits often match older 3-digit numbering systems, while the last 2 digits indicate more modern variations. For example, Stainless Steel Type 310 in the original 3-digit system became S31000 in the UNS System. The more modern low-carbon variation, Type 310S, became S31008 in the UNS System.
For heating, resistance wire must be stable in air when hot. Kanthal FeCrAl alloy forms a protective layer of aluminium oxide (). [1]Aluminium oxide has high thermal conductivity but is an electrical insulator, so special techniques may be required to make good electrical connections.
It markets products through subsidiaries in the United States, Australia, Germany, [7] Belgium, United Kingdom, China and New Zealand. [1] [2] Their facilities in Warminster include a private railroad spur, served by the New Hope Railroad. Traffic on the spur constitutes a sizable portion of the railroad's freight traffic; CRC Industries is ...
[7] In November 1940, United States Steel Export Company reached an agreement to sell Kennametal tools, tool blanks, drawing dies and other Kennametal products in foreign markets. [ 8 ] During World War II, more than 50% of the artillery shells produced in the United States were machined with the Kennametal product. [ 9 ]
