unwrought Button metal alloys (zinc predominating)
Other materials being investigated for use in future lithium-ion batteries include tin alloys and silicon.
Common materials for the MTJ include chromium dioxide and iron-cobalt alloys.
Molybdenum and vanadium are used as alloys for steel to prevent corrosion.
But steel alloys subjected to cyclic stress levels below their endurance limit rarely fail as a result of fatigue.
"The pure metal is too hard to work with to have any significant uses; alloys with platinum are used in jewelry, pen points, surgical pins and pivots, electrical contacts and sparking points, and extrusion dies."
Shenzhen Hengfa Mentalwork Company is an enterprise mainly producing various locks of communication-boxes( or cupboardes), accesseries of funiture, developing molds and engaging in frabrication and casting of zenic alloys.
"It is the catalyst for converting ethylene to ethylene oxide, the precursor of many organic chemicals. Its use in alloys in sterling (92.5% silver, 7.5% copper) and plated silverware, ornaments, and jewelry remains important;"
This paper reviews the corrosion resistance of various dental alloys evaluated in the light of their released ions in experiments, and shows the examples in which original corrosion resistance is lowered by the factors such as casting, polishing and contact with other metals.
