Why choose Tungsten carbide Rings ?
Tungsten carbide has become a popular material for jewelry,
especially for men jewelry and wedding jewelry. Tungsten is roughly
10 times harder than 18K gold (gold being the traditional material
of wedding bands), 5 times harder than steel, or about 4 times as
hard as titanium. Tungsten Carbide’s hardness is between 8 and 9 on
the Mohs hardness scale. Diamond’s hardness is 10, the hardest
material on the planet. Tungsten Rings will hold their shape, no
bending.
Tungsten carbide Rings Description
Carbide rolls are widely used in metal forming, especially in hot
rolling industry mainly for intermediate and last finishing stands
to ensuring superior surface finish and dimensional stability of
processed metal products. Rolls are also commonly used for wire
flattening, de-scaling and straightening applications.
