Nicrofer 5716 alloy is a nickel-chromium-molybdenum alloy containing tungsten and low amounts of carbon and silicon. The alloy is characterized by excellent resistance to stress corrosion cracking, crevice corrosion and pitting.
Sanicro 70 is an austenitic nickel-chromium-iron alloy that is characterized by excellent resistance to nitrogen absorption and carburization, and good structural stability at high temperatures. It also has good resistance to stress corrosion cracking.
Super alloy VLX800H is a slightly modified version of Incoloy 800 with the 800H grade possessing higher creep and rupture strength. This modification is possible because of the closely controlled carbon content and modified heat treatment.
The Unified Numbering System (UNS) designation comprises five digit numbers preceded by a letter prefix. The letter indicates the identified metal family. UNS C50715 is a copper alloy.
UNS designations C50100 to C54200 are called phosphor bronzes. Phosphor bronzes are copper alloys containing predominantly tin and phosphorous. Tin provides these alloys increased corrosion resistance and strength, while phosphorous provides them increased wear resistance.
Copper can be combined with other metals such as tin, silver, chromium, and zinc to make alloys. Copper and its alloys are essential materials in most of the electrical applications.
Copper and its alloys are particularly known for their good electric and thermal conductivity and corrosion resistance. They are used in a number of applications, by varying their properties which are based on the amount of impurities that are alloyed.
Magnesium is a highly versatile metal which is non-toxic, and has excellent machining qualities. It exhibits a capacity to dampen and absorb vibration and electromagnetic waves.
