Industrial Rollers: What is the Difference Between Chromium Carbide and Tungsten Carbide Coatings?

Industrial Rollers: What is the Difference Between Chromium Carbide and Tungsten Carbide Coatings?

The hardness of tungsten carbide coated rollers is significantly higher than that of chromium carbide. The Mohs hardness of tungsten carbide is close to 9, second only to diamond, while the hardness of chromium carbide is relatively low. Therefore, in applications where extreme wear resistance is required, tungsten carbide coated rollers perform better.

How to tell if the tungsten carbide coating of industrial rollers is real?

How to tell if the tungsten carbide coating of industrial rollers is real?

One of the most direct ways to identify tungsten carbide coatings is to conduct a hardness test. Tungsten carbide has extremely high hardness, usually reaching 70HRC (Rockwell hardness) or more. Therefore, the hardness of the coating can be tested by using tools such as Rockwell hardness tester.

Which rollers are needed in the automobile manufacturing industry?

Which rollers are needed in the automobile manufacturing industry?

7 types of rollers needed in the automobile manufacturing industry: 1. Coating Roller, 2. Embossing Roller, 3. Chrome Plated Roller, 4. Tungsten Carbide Roller, 5. Guide Roller, 6. Heating Roller, 7. Cooling Roller.

What is the hardness of industrial carbide rolls?

What is the hardness of industrial carbide rolls?

The hardness of carbide rollers is usually closely related to the alloy composition used. Carbide rollers are mainly composed of elements such as tungsten, carbon and cobalt, and different alloy formulas will affect their hardness. Specifically, the hardness of carbide rollers is usually between 55-80 HRC (Rockwell hardness C scale).

Why are industrial carbide rollers so expensive?

Why are industrial carbide rollers so expensive?

The core components of carbide rollers are metals and compounds such as tungsten, cobalt and carbon. Tungsten, as one of the main raw materials of carbide, has extremely high hardness and wear resistance, while cobalt, as a binder, plays a role in increasing the toughness and thermal stability of the alloy. The prices of tungsten and cobalt are high in themselves, which greatly increases the production cost of carbide rollers.

Will the chrome coating of industrial chrome rollers fade?

Will the chrome coating of industrial chrome rollers fade?

In theory, the chrome layer will not fade under most working conditions. The stability of chrome metal itself is extremely high, and the chromium oxide layer on its surface can effectively prevent the external environment from corroding the chrome layer. Therefore, the chrome layer can usually maintain its original luster and color for a long time and is not easy to fade.

Why does the aerospace industry need water quenching rollers?

Why does the aerospace industry need water quenching rollers?

In aerospace manufacturing, the processing of each component requires extremely high precision. Water quenching rollers can ensure the uniformity and stability of the quenching treatment, so that the performance of each metal workpiece is consistent.

Which industries need to use rubber rollers?

Which industries need to use rubber rollers?

Industries that need rubber rollers include: printing industry, packaging industry, textile industry, paper industry, metal processing industry, food processing industry, electronics industry, automobile manufacturing industry, etc.

Industrial tungsten carbide coated roller: How thick is the tungsten carbide coating?

Industrial tungsten carbide coated roller: How thick is the tungsten carbide coating?

The thickness of tungsten carbide coatings is usually between 50 microns (0.05 mm) and 500 microns (0.5 mm), depending on the application scenario, working environment and use requirements of the roller. The choice of coating thickness must balance the wear resistance, impact resistance and other working characteristics of the roller.

What is the price of tungsten carbide coated roller in US dollars?

What is the price of tungsten carbide coated roller in US dollars?

The following is an approximate price range based on market research: small tungsten carbide coating rollers ($500 to $1,500), medium tungsten carbide coating rollers ($1,500 to $5,000), and large tungsten carbide coating rollers ($5,000 to $20,000).
