Tungsten is a rare natural earth metal. It is classified as a refractory metal due to its very high melting point (3422°C) and low vapor pressure. It also has the highest tensile strength of all metals at temperatures over 1650°C. It is incredibly dense, with a density similar to gold and uranium. In fact, tungsten even means "heavy stone" in Swedish. Tungsten is typically alloyed with other materials because pure tungsten is extremely brittle and difficult to machine. An unbelievable display of density Machined from aerospace grade tungsten, this tungsten alloy cube is an excellent contemporary addition for your desk at work or bookshelf at home. Though our tungsten cubes may seem small, due to tungsten's high density they are extremely heavy for their size. Whether you are a science enthusiast or are looking for a beautiful desk toy, our tungsten will be sure to amaze you and your friends with its mind-boggling density. Includes certificate of chemical composition and interesting tungsten facts. Size: 3.81 cm x 3.81 cm x 3.81 cm (1.5" x 1.5" x 1.5") Weight: 1 kg Composition: 95% tungsten, 5% nickel/iron Slightly rounded edges for safe handling Engraved Element Cube Set Five piece display set including 1" cubes of copper, aluminum, titanium, iron, and tungsten. 3.81 cm (1.5") Tungsten Cube Our famous tungsten cube is an incredible display of density.

Tungsten is not refined by smelting or in a manner similar to many other metals due to the fact that it has the highest melting point of any metal. Tungsten is, therefore, extracted chemically from the crushed ore in a series of chemical reactions, titrations, washings, and filterings. The end result of the refining process is high purity tungsten powder. To consolidate tungsten powder it may be blended with a binder and very small amounts of other materials that will provide desired properties to the finished product. The most common method of consolidation is sintering. Tungsten powder is pressed into cakes or fragile bars which are heated in a furnace until the particles adhere to one another. The bar is then placed in a sintering bottle for further heating. Electric current is run through the bars until they become extremely hot, and the individual tungsten grains merge together and form a solid part. During this process the bar shrinks and becomes more dense. Alloys do not require millwork to enhance properties in the same way that pure tungsten does, but may be worked anyway to achieve desired shape. These heavy metal alloys are quite useful for many purposes and are machined much more easily than pure tungsten. Each of these steps adds cost to the final product. A broad range of prices for finished tungsten products would be from $25 to $2500 per kilo, with the majority of products in the $100 to $350 per kilo range. **Q: Deciding btw 1" & 1.5" tungsten cube. site says 1" weighs .66 lb and 1.5" weighs 2.2 lb. (1kg). is that right? i can't make the math work. help?** A: 1" cube = 1"×1"×1" which is 1inch³. 1.5" cube = 1.5"×1.5"×1.5" which is 3.375inches³. Therefore it is 3.375 times the mass of the smaller cube. **Q: What is the chemical composition of the cube? How much tungsten ie 90%, 95%, 100%?** A: The cube is 95% tungsten with nickel-iron for the remainder. **Q: Will this cube ever oxidize or corrode in any way?** A: my cube has stayed pristine for over a year. I just wipe fingerprints off off it with lens cleaner cloth. My wife thinks i am an idiot for liking it - but that probably makes me like it even more. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The cube is good *by O***E on 12 June 2026* All hail the cube ### ⭐⭐⭐⭐⭐ You want a Tungsten cube?
