Hard alloy rings are made of tungsten, the hardest metal on Earth. They are harder than titanium rings and have a longer lifespan than gold rings. These rings are commonly used as sealing strips, disc cutters, instruments, and so on.

What is the difference between tungsten rings and hard alloy rings?
Some manufacturers sell tungsten rings that do not contain hard alloy (however, some retailers still refer to them as hard alloy, so you need to be careful). A tungsten ring is essentially a steel ring. It is very hard, but it cannot prevent scratches. Only diamonds or products containing mineral corundum materials can scratch hard alloy rings.

Examples of Hard Alloy Ring Hardness:
1. Hard alloy rings are the most wear-resistant rings on Earth.
2. The hardness of tungsten is 10 times that of gold, 5 times that of tool steel, and 4 times that of titanium.
3. Due to the extremely high hardness of hard alloy rings, they can maintain their shape and their luster lasts longer than any other material on the market.
4. Hard alloy rings are called "permanent polishing rings".
5. Hard alloy rings will not deform.
