Economical Grade 70% Silicon Carbide Supplier For Foundry
Looking for cost-effective 70% silicon carbide? ZhenAn's Economical Grade 70% Silicon Carbide offers stable SiC content, multiple particle sizes, customized packing, third-party inspection, and reliable bulk supply for industrial applications.
Products Description
70% silicon carbide is a highly cost-effective industrial grade, offering a lower cost compared to higher-purity alternatives. Silicon carbide (SiC) itself is artificially synthesized from silicon and carbon, possessing high hardness, excellent wear resistance, high-temperature resistance, good thermal conductivity, and extreme chemical stability. For many conventional applications (such as metallurgy, foundry, and refractory production), a 70% SiC content is sufficient to meet basic performance requirements, avoiding the unnecessary expense of higher-purity materials that do not provide additional value.

Industrial Applications of 70% Silicon Carbide
In actual production, 70% silicon carbide is mainly applied in the following fields:
Metallurgical Industry
In metallurgical production, 70% silicon carbide is commonly used as a deoxidizer or alloy additive, suitable for conventional steelmaking processes such as electric furnaces and converters. This grade of product can provide effective SiC content while reducing slag oxidation and improving the fluidity of molten steel. For production scenarios like ordinary carbon steel and cast iron, which are cost-sensitive and do not require high-purity silicon carbide, 70% silicon carbide is a practical choice that balances performance and cost.
Foundry Industry
In the foundry field, 70% silicon carbide is mainly used in processes such as inoculation treatment, molten iron conditioning, and in-furnace carbon and silicon addition. It helps stabilize the graphite morphology in cast iron, reduces the chilling tendency (white iron tendency), and improves the machinability of castings. For the production of conventional castings such as ordinary gray cast iron and ductile iron, using 70% silicon carbide to replace high-purity grades can effectively control the unit consumption cost of auxiliary materials while ensuring metallurgical effects.
Refractory Industry
In refractory formulations, 70% silicon carbide is commonly used to prepare products such as blast furnace ceramic cups, iron runner castables, alumina-carbon bricks, and slide gate plates. It can improve the materials' resistance to slag corrosion, thermal shock resistance, and thermal conductivity. For refractory products with non-extreme operating conditions and low requirements for SiC purity, using 70% silicon carbide as an aggregate or fine powder component can significantly reduce the raw material cost of the formulation while meeting service life requirements.
General Industrial Applications
In addition to the above fields, 70% silicon carbide is also suitable for abrasives (such as low-to-medium-grade fillers for grinding wheels and abrasive cloths), ceramic products (such as kiln furniture and setter plates), as well as aggregates for certain anti-corrosion coatings or wear-resistant floors. These application scenarios are usually insensitive to SiC purity, placing more value on the material's hardness, wear resistance, and cost controllability. 70% silicon carbide can provide stable physical properties in these fields and achieve better cost-effectiveness than high-purity grades.
