Pure tungsten is a highly durable grey metal that makes up a small fraction of the earth’s crust (around 1/20 ounce per ton of rock). Tungsten does not occur as a pure metal in nature but instead is always combined as a compound with other elements. The high scratch resistance and durability makes it the ideal choice for jewelry. The metal is alloyed with a superior nickel binder to produce a hard, strong and scratch resistant piece of jewelry.
Why Tungsten Carbide?
Platinum, palladium or gold rings have the ability to easily scratch, dent and bend. Tungsten rings do not bend and will remain looking exactly as beautiful as the day you first bought it. Tungsten is a harder and denser metal. You can feel the quality in the heavier weight in tungsten. When you combine the solid weight and everlasting polish of tungsten together in one ring, you produce a perfect symbol of your love and commitment.
Facts About Tungsten:
Chemical Symbol: W
Atomic Number: 74
Melting Point: 10,220 degrees Fahrenheit (5,660 degrees Celsius)
Density: 11.1 ounces per cubic inch (19.25 g/cm)
Isotopes: Five Natural Isotopes (around twenty-one artificial isotopes)
Name Origin: The word “tungsten” comes from the Swedish words tung and sten, meaning “heavy stone”
The Manufacturing Process
Tungsten powder is packed into solid metal rings using a process called sintering. A press tightly packs the powder into a ring blank, then the ring is heated in a furnace at 2,200 degrees Fahrenheit (1,200 degrees Celsius) and the tungsten wedding bands are ready for sintering. This involves passing an electric current directly through each ring. As the current increases, the ring heats up to 5,600 degrees Fahrenheit (3,100 degrees Celsius), shrinking into a solid ring as the powder compacts.
The ring is then shaped and polished using diamond tools. For rings with silver, gold, palladium, platinum or mokume gane inlays, diamond tools dig a channel into the center of the ring. The precious metal is inlaid into the ring under pressure and re-polished.
To ensure your tungsten ring will remain looking as beautiful as the day you bought it, here are a few tips to keeping it looking so wonderful.
1. Although your tungsten ring is highly durable and scratch resistant, do not drop your ring onto a hard surface or intentionally strike it with a hammer. Since tungsten rings do not bend, they will shatter when enough force is applied.
2. Clean your tungsten ring with gentle soap and water, do not use any chemicals such as ammonia, bleach and chlorine because this may cause spotting.
Tungsten rings are extremely hard and standard cutting devices will not be able to remove them in an emergency. You must remove the ring by a pair of standard vice grips. Insert your ring and your finger into the vice grips. Adjust the tightener until you hear a crack. Give the ring a quarter turn and repeat until the ring has completely broken off your finger. Take care not to slide the cracked ring up and down your finger. If your tungsten ring has a precious metal inlay, the platinum, palladium, gold or silver may be cut in the regular method. The entire process should take less than 30 seconds to complete and emergency personnel are equipped with these removal devices.
