Durable Tungsten Carbide Seal Rings , Tungsten Carbide Rolls Wire Rod Mills
Tungsten Carbide Seal Rings advantage
1) It is not like silver will get black, not like copper jewelry allergy prone,not like alloy jewelry because of lead.
2) It is heavier than most metals because of its density.
3) The hardest form of tungsten carbide is harder than titanium alloys.
4) Tungsten carbide jewelry does not tarnish and oxidize, You can't beat its shine and polish.
5) It's Cobalt Free and Hypoallergenic, so if you have any allergies, it won't happen with tungsten.
6) Tungsten rings will never bend and never scratch. File away at it, and it will stay polished forever.
7) Tungsten rings are very hard, affordable, last longer, do not fade, and come in more shapes and styles.
8) Tungsten Jewelry are imperceptible in difference to more expensive rings yet require less care and cost less money.
Tungsten Carbide Seal Rings Advantage
Tungsten carbide rollers possess good thermal conduction property.
Compared with other materials ,it is much better in term of heat-resistance,
wear-resistance and strength. Its hardness reduce a litte under the condition of high temperature.
