Why do people make wire with platinum?
482123
Platinum wires are chemical and heat resistant (higher melting point than copper, silver, gold, etc.).  They are NOT better conductors (the opposite), it is rather their ability to tolerate higher temperatures that makes them useful.\n\nAlso, platinum/platinum-alloy wire pairs are used for thermocouples that are accurate at high temperatures, and pure platinum wire is used for resistance thermometers that are used for the same purpose.

They use stainless steel wires, and its not a neat job. You should see my X ray pictures. It looks like my three year old trying to lace his shoes.

Tungsten mostly, but there are other metals used. There are also gasses that glow too in bulbs that have no filiment wire.

White gold refers to an alloy of gold and other white metals such as silver, palladium, or nickel. The natural colour of white gold is light gray, so jewelry made of white gold is typically coated in highly reflective rhodium (sometimes coated in platinum and palladium), adding a more brilliant shine. Palladium and silver alloys are of higher quality than nickel and are sometimes not coated with rhodium. The purpose of plating is to add luster to grayer jewelry, as well as to prevent oxidation of some of the metals found in the alloys. White gold is not platinum, but is used as a cheaper alternative, usually costing one-third as much as platinum

Electricity is simply electrons in motion.  Iron, in its pure state, has free electrons available. (note that all metals, either pure or as an alloy, will have some free electrons available; hence metals are typically good conductors.)  \nA more complete picture of the process would look like this:  These free electrons are on the outside surface of the wire.  Now envision ; as you apply current-more electrons- to the wire, these electrons move along the wire and bump into the available free electrons on the surface, thus pushing them along and allowing the current to flow.  This process causes a certain amount of friction and explains why the wire warms up

The metal is corrosion-resistant. The catalytic properties of the six platinum family metals are outstanding (a mixture of hydrogen and oxygen explodes in the presence of platinum). For this catalytic property, platinum is used in catalytic converters, incorporated in automobile exhaust systems, as well as tips of spark plugs.\nPlatinum possesses remarkable resistance to chemical attack, excellent high-temperature characteristics, and stable electrical properties. All these properties have been exploited for industrial applications.

You need two different kinds of metal. Copper is easy for one. The other can be almost any non-copper metal. Simple trial and error should show you a good choice. \n\nTry: nails, silverware, pointy tools (screwdrivers), bits of metal from craft or hobby jobs, coat hangers, etc. You can even jam coins in there!

this is because gold has lustre or shinning surface when polished. it can also be hammered to shape maleable since it is soft

No, copper is NOT cheap, it costs quite a bit more than aluminum pound for pound. Copper has a much lower resistance to electricity than aluminum does. When subjected to the loads household wiring have to deal with, aluminum wiring would have to be prohibitively thick to prevent overheating. Copper provides the best conductivity with the best compactness for the best price.

because it depends on the purity(karat)of the gold solution used  for the plating of any metal object.\n\ngold ions from the gold object and the gold solution will be transferred to the object to be plated\n\nif you want to plate the object to be 16K then you use an 16K soulution with an object that contains 16k purity

I don't remember the ordering, but there's probably some metal out there that won't react?  Gold, maybe?  For regular metal, that sounds a bit iffy.

because it stops corrosion to the steel which would rust and therefore increases the shelf life of the wire the same as it would mig or gas welding filler\n\ngaz

If it's a property of a metal, it's referring to the metal's ductility.  Metals like silver and copper have a high ductility - meaning they can be drawn into wires by a mandrel quite easily.  Titanium has a very low ductility - meaning the metal will tend to break if drawn.

Titanium is not worth as much as platinum.  It is much more common in the earth's crust as fairly common minerals such as rutile and illmenite (occurs in weight % abundances in the rock).  Platinum however occurs only in very unusual environments and in low ammounts (occurs in parts per million - or grams/ton in the rock), and so it is "worther".

that's a very challenging question, it is possible to produce strings of iron atoms a few nm across, but at that size they would obviously lose the properties of stainless steel, the resulting question would be, how small can wire be produced and still be considered to be of a certain alloy?  (this discussion refers to high precision lab production, not industrial production)

The platinum group or platinum metals is the collective name sometimes used for six chemical elements within the periodic table. These elements are all transition metals, lying in the d-block (groups 8, 9, and 10, periods 5 and 6 - in Mendeleev's original table, this area was called "Group VIII").\n\nThe six platinum metals are: ruthenium, rhodium, palladium, osmium, iridium, and platinum. They have similar physical and chemical properties, and tend to occur together in the same mineral deposits.

Because METAL is in some way 4 different evolving atoms and\n  materials according to the measurement of dense fields do in\n  scientific quantity.  By this we can mean practical, or reachable\n   thus according in some way to eliminate areas like highest\n   or wildest regions not likely to take production.  So on, under\n    the ocean, so I eliminate all except production and storing in\n    prepared or piled supply site.  Two come into active,  uranium\n    is the general metallic under cooling storages in slabs to be\n    readily available up to 40 million tons per harvest, this is like\n    a magical fuel bar supply for gigantic space stations.  The 2nd\n    choice is more likely GOLD, due to it being mapped, sited,\n    and gaining value in technology for unforeseen many years.\n    Theory only Gold smelt slab 90% style could be done in a\n     magic superior at 1 billion pounds per year for periods of 30 \n     years from existing process of purification and not going\n     deeper then 2 miles below the surface.  Nice question.
