Solid Tungsten Carbide is more than a scratch-proof metal. Our Hadron model displays Tungsten’s incredible luster which our videos can only barely capture. This modern watch will hypnotize anyone who even glances.  

The name “Hadron” comes from the sub-atomic particle. Discovering the secrets of the universe by using incredible amounts of energy to break open the hadron is the goal of CERN’s famous “Large Hadron Collider”

SOLARRI tungsten carbide watches are hand polished with diamond dust to a microscopically smooth, astonishing, and everlasting mirror shine. This shine is so astonishing due to the interplay of reflected and refracted light, that only seeing one in person can do it any justice. SOLARRI’s tungsten watches also display the natural 5% tint of Titanium color- characteristic of the carbon when mixed with tungsten. At a 5,200° melting point, SOLARRI tungsten carbide watches necessitate a proprietary method of manufacture. Due to the incredible and laborious processes necessary to properly create such a watch, others can only poorly imitate the look. 

SOLARRI’s new line of genuine tungsten carbide watches are at the absolute forefront of watch design, quality and durability. SOLARRI watches embody ultra modern flare with homage to classic roots. Add in a genuine Swiss movement, and the ideal watch is conjured.

Excellent Hardness: 86~93 HRA, which equal to 68~81HRC;
Excellent hot working performance: Hardness could be remained at 60 HRC under 900~1000 ℃;
Resistance to wear: Some grades can outwear hardened steel by over 100 times
Resistance to corrosion: Grades with Nickel and Chromium binders are very resistant to acidic solutions
Impact resistance: Cemented carbides are surprisingly tough considering their high hardness.

Tungsten cemented carbide is the preferred material for parts that must withstand all forms of wear (including sliding abrasion, erosion, corrosion/wear and metal-to-metal galling) and exhibit a high degree of toughness. It exhibits high compressive strength, resists deflection, and retains its hardness values at high temperatures, a physical property especially useful in metal-cutting applications. It provides long life in applications where other materials would not 0ast or would fail prematurely.

Tungsten carbide has a high melting point at 2,870 °C, a boiling point of 6,000 °C when under a pressure equivalent to 760mm of Hg, a thermal conductivity of 84.02 W·m−1·K−1, and a coefficient of thermal expansion of 5.8 µm·m−1·K−1.
Tungsten carbide is extremely hard, ranking ~9 on Mohs scale, and with a Vickers number of 1700–2400. It has a Young's modulus of approximately 550 GPa, a bulk modulus of 439 GPa, and a shear modulus of 270 GPa. It has a very high yield stress at 6800 MPa, but a comparatively low ultimate tensile strength of just 35 MPa.
The speed of a longitudinal wave through a thin rod of tungsten cemented carbide is 6220 m/s.
With a low electrical resistivity of, tungsten cemented carbide's resistivity is comparable with that of some metals.
WC is readily wetted by both molten nickel and cobalt. Investigation of the phase diagram of the W-C-Co system shows that WC and Co form a pseudo binary eutectic. The phase diagram also shows that there are so-called η-carbides with composition (W,Co)6C that can be formed and the fact that these phases are brittle is the reason why control of the carbon content in WC-Co hard metals is important.

There are two well characterized compounds of tungsten and carbon, WC and tungsten semicarbide, W2C. Both compounds may be present in coatings and the proportions can depend on the coating method.
At high temperatures WC decomposes to tungsten and carbon and this can occur during high-temperature thermal spray, e.g., in high velocity oxygen fuel and high energy plasma methods.

Oxidation of WC starts at 500–600 °C. It is resistant to acids and is only attacked by hydrofluoric acid/nitric acid mixtures above room temperature. It reacts with fluorine gas at room temperature and chlorine above 400 °C and is unreactive to dry H2 up to its melting point. WC dissolves readily in diluted hydrogen peroxide.
