Description
Chromium carbide (Cr3C2) is a hard, orthorhombic crystal with the highest oxidation resistance at high temperatures among all metal carbides. It is also resistant to acids and alkalies, making it a versatile material for various applications.
Uses
1. Die-Casting Industry:
Chromium carbide is used as a high-temperature oxidization-resistant coating for aluminum and magnesium die-castings, providing protection and enhancing the performance of the castings.
2. Surface Treatment:
Chromium carbide is used in the surface treatment of metal components through a technique known as thermal spraying. This process involves coating the surface of another metal with chromium carbide to improve its properties.
3. Cutting Tools Industry:
Chromium carbide is used as an additive in cutting tools made out of cemented carbides. It improves the toughness of the tools by preventing the growth of large grains, which can compromise the tool's performance.
4. Ceramics:
Chromium carbide ceramics are potentially useful materials due to their excellent electrical conductivity, high hardness, moderate melting point, and good chemical stability. This makes them suitable for various applications in the ceramics industry.
5. Wear-Resistant Coatings:
Chromium carbide is used to provide hard, wear-resistant coatings on parts that need protection. When combined with a protective metal matrix, corrosion-resistant and wear-resistant coatings can be developed that are easy to apply and cost-effective. These coatings can be applied through welding or thermal spray techniques.
6. Cutting Tools (Advanced):
When combined with other carbides, chromium carbide can be used to form advanced cutting tools with enhanced performance and durability.
7. Welding Electrodes:
Chromium carbide welding electrodes are increasingly used instead of earlier ferrochrome/carbon-containing electrodes. They provide superior and more consistent results, leading to a harder wear-resistant layer in the weld deposit. This results in reduced wear rates compared to welds deposited from ferrochrome/carbon electrodes.

Check Digit Verification of cas no
The CAS Registry Mumber 12012-35-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,1 and 2 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 12012-35:
(7*1)+(6*2)+(5*0)+(4*1)+(3*2)+(2*3)+(1*5)=40
40 % 10 = 0
So 12012-35-0 is a valid CAS Registry Number.
