ANSWER......

Noble metals used for dental castings continue to consist of alloys of gold, palladium, and silver (not a noble metal), with smaller amounts of iridium, ruthenium, and platinum. The majority are used as a backing for ceramic baking, with the rest used as inlays, onlays, and unveneered crowns.

Hi friend here is ur query..

___________________


Noble metals are inert, and are highly resistant to oxidation and corrosion when exposed to moisture. These metals are rare and highly prized. Noble metals, however, are not the same as “precious metals” even though many of the noble metals, such as gold and silver, come under the category “precious metals.” Examples of noble metals include platinum, iridium, osmium, palladium, rhodium and ruthenium. Metals such as titanium, niobium and tantalum, though highly resistant to corrosion, are not considered as noble metals.

There are many uses of noble metals.

* Palladium is used in jewelry, dentistry, blood sugar testing strips, watchmaking, spark plugs for aircraft, surgical instruments and transverse flutes.

* Iridium has many industrial uses because of its hardness, high resistance to corrosion and high melting point. It is widely used in spark plugs, electrodes and catalysis
.

* Platinum, gold and silver are considered bullion metals, and are extensively used to make jewelry and coins.

* Silver is also used in medicines due to its antibacterial properties. 


* irradium Its alloys with platinum and osmium have been used historically in pen nibs and cannon vents. Iridium is extensively used in machinery parts like spinnerets (small metal plates with fine holes), for balances and compasses, air craft parts and deep water pipes, high-temperature crucibles and catalysts
