Titanium in the Manufacture of Jewellery

The element titanium is second only to platinum in its highly desirable qualities as a metal. It is more scarce than iron but not as scarce as steel. It is somewhat expensive to refine, but can be used to manufacture airplanes and rust free coatings.

Similar to jewellery metals, it is resistant to corrosion. Similar to steel, it is incredibly strong. Its luster, scarcity, and absolute durability causes it to be employed in jewellery making.

Titanium Whips Silver in a Strength Match

Titanium has the highest strength-to-weight ratio of any metal, and it is less expensive than silver. Resistant to corrosion, it can be stamped and buffed to a high luster. It can form the chain or bindings of jewellery without any additional coating. It does not stand out as dull compared to silver and gold and might even be considered a semi-precious metal.

A pendant might be suspended on a very wispy metal chord. In spite of being thin and flexible, it is incredibly strong and will not break. Titanium is one of the few metals that can reliably achieve this effect, because while the outer layer might consist of silver threads, the core is mighty Ti. It is critical to remember this fact while making jewellery: Silver is more lustrous but titanium is both strong and lustrous. Titanium is also easy to plate.

Titanium is Cheaper Than Platinum But is Similar

The first aspect of titanium in contrast with silver and gold is the high melting point. The atoms are joined much more strongly and will not break their crystal structure except at high temperatures. This is an important note when using titanium and gold together. Gold will easily plate onto titanium but titanium cannot easily plate onto gold because of the different melting temperatures.

On the other hand, titanium is a great substitute for platinum. They are both resistant to corrosion and are lustrous. Very few applications require platinum where titanium will not substitute. Consider this fact when using Platinum, an element that is often twice as expensive as gold.

5 Things You Didn't Know About Titanium

Titanium is a surprisingly common and very useful silvery metal, but it is so much more. I bet you didn't know half of all the amazing things titanium has to offer. Here are 5 things you probably didn’t know about this awesome metal:

1. Titanium is extremely lightweight.
What? I thought metal was heavy! Nope. Unlike most metals, titanium is extremely lightweight. In fact, it is well-known for its high strength-to-weight ratio. It is a light, strong metal with a low density and that makes it quite easy to manipulate. Titanium is so strong and light that its strength is equal to alloy steels,while remaining 45 percent lighter.

2. Titanium is very tough.
Unlike steal, titanium is resistant to corrosion from salt water, making it perfect for underwater mechanical devices such as propellers and heat exchangers in desalination plants, the temperature control devices in salt water aquariums, and even divers' knives. Titanium is even more resistant to tarnishing in open air. Now that's tough!

3. Titanium is literally everywhere!
Titanium is found in just about all living things! Yes, that’s right, from water, to soil, to rock this ore exists in just about everything, even in meteors and in our sun in outer space. It is likewise used to make many things that are used every day. It is in our cell phones, jewelry and dental implants. It can be found in the tools that doctors and dentists use. As well as being responsible for the twinkle in some precious stones such as sapphire and rubies.

4. Titanium is resistant to extreme temperatures.
This means titanium can be used in all sorts of really harsh environments where steel just won’t cut it such as in the air, underwater, and in outer space. It is used in airplanes, armor plating for bullet-proof vests, naval ships, submarines, satellites, space shuttles, and missiles.

5. Titanium Helped America win the Cold War against the Soviet Union in the mid twentieth century.
 In this historical event the Soviet Union tried to stop America from purchasing titanium to use in its aircraft. They failed, however, in their efforts when America was able to secure and purchase large quantities of titanium with help from a European company.

In short, titanium is one of the most versatile and plentiful metals on the planet and now we know five important things about it that we did not know before.
