Tungsten Forever offers only the highest-quality designer tungsten carbide products, enforcing standards most choose to ignore. For example, all Tungsten Forever rings are cobalt-free (rings containing cobalt can irritate the skin, can crack or shatter under pressure and are easily scratched). Tungsten Forever rings also pass through a rigorous quality-control inspection and are designed for the best look, feel and fit.

Some of our competitors sell tungsten rings that are not tungsten carbide. (Some of the retailers even still call them tungsten carbide, so be careful.) A tungsten ring is only the basic element without the strengthening of alloy. It is very hard, but NOT scratch-proof. A Tungsten | Forever carbide ring can only be scratched by a diamond. If you see a tungsten ring that has carved details this ring is tungsten carbide - it is a tungsten-only ring. Therefore, it will scratch. See similar questions...

Cemented carbides consist of hard grains of the carbides of transition metals (Ti, V, Cr, Zr, Mo, Nb, Hf, Ta, and/or W) cemented or bound together by a softer metallic binder consisting of Co, Ni, and/or Fe (or alloys of these metals). Tungsten carbide (WC), on the other hand, is a compound of W and C. Since most of the commercially important cemented carbides are based on WC as the hard phase, the terms "cemented carbide" and "tungsten carbide" are often used interchangeably.

Typical cladding thicknesses are in the 0.020” - 0.060” (0.5mm-1.5mm) range. If required, thinner or thicker claddings can be applied. See similar questions...

It is possible to have any of our rings engraved using our laser etching system. To have a ring engraved, complete a purchase and we will send the ring to you to verify it truly matches your needs before it is engraved. After you have received the ring, you can send it back to us at your leisure for etching. The cost for etching is $25 per ring, and would take 1-2 business days. We are able to engrave up to 30 characters per ring. See similar questions...

Although the difference is difficult, if not impossible, to physically measure with instrumentation, the experts [with those precious "tuned ears"] say that Tri-Orbs sound much better in overall listening tests (i.e. tighter base, enhanced mid-range clarity, crisper highs, more dynamic soundstaging, etc., etc.). The two metals themselves are very different in composition. TC is a very heavy metal, about twice the physical weight of steel, revealing a density of 15. See similar questions...

The important difference where darts are concerned is their strength. The stronger the metal, the slimmer the dart can be and the easier it is to group them together for high scores. Tungsten is the strongest metal followed by Nickle and then Brass. See similar questions...

When used for housing, the general trend is to use diamond cut Carabooda limestone blocks for a more formal finish, or the more textured biscuit coloured Moore River Limestone blocks to create a character natural stone feel ? it is simply a matter of personal preference. Quarry cut limestone blocks are cut directly from the quarry floor using electric saws with tungsten tipped blades. See similar questions...

All rings are measured from the inside edge to the other inside edge. This is their inner diameter (ID) The nylon rings are SMALL 2 1/4"(5.7 cm), MED 2 5/8" (6.7 cm), LARGE 2 7/8" (7.3 cm) and are 0.4" (1 cm) thick. The aluminum rings are SMALL 2" (5 cm) MED 2.5" (6.4 cm), LARGE 3" (7.6 cm) and 0.25" (.64 cm) thick. See similar questions...

It is fine to wash slings made with our rings in a regular washer. They can also be dried in the drier. You should check your sling and rings carefully after they are washed and dried and before you wear them again. See similar questions...

Currently nylon rings are available in black, white, grey, ivory and navy (the "neutrals") and blue, green, purple and burgundy (the "colors") Aluminum rings are at present available in black, silver, gold and brown/bronze (the "neutrals") and blue, green, purple, turquoise and red (the "colors"). See pictures on the colors page. See similar questions...

Our rings are priced as they are for two main reasons. The first is that they are made in the USA. We pay our workers a living wage. The second is that our rings are made especially for use in baby slings, which means that we put them through two and three extra processes to make sure that they are smooth and h4 and safe. We use only the highest quality materials for these same reasons. See similar questions...

Generally rings are shipped the next business day after they are ordered. There are occasional delays, but rings are always shipped within 2-3 business days.

AS568A number is a three-digit suffix that identifies the O-ring's size. The SAE (Society of Automotive Engineers) published the original document that established these o-ring sizes. The AS in AS568A stands for Aerospace Standard. These o-ring sizes are standard throughout the o-ring industry and also in most military applications. AS568 is generally considered to be the U.S. size standard and there is no difference between the AS568A or AS568B designation. See similar questions...

A:If you click on the 'SHAPE' link at the top, this will give you a description and a view of all the styles. Most rings come in light/ med heavy etc.this refers to the weight of the ring. Generally speaking Ladies sizes are o.k. in light weight and upwards. Mens ring are more robust in medium upwards. The extra light weight is very very light and really for small finger sizes only.
