Silicon Carbide 75% Bulk Supply With Fast Delivery
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
Silicon Carbide 75% is a practical industrial-grade material widely used in foundry, metallurgy, and refractory applications. With 75% minimum SiC content, it offers a balanced combination of usable silicon carbide content, controlled impurity levels, and competitive cost for regular industrial purchasing.
For many buyers, Silicon Carbide 75% bulk supply with fast delivery is especially valuable in applications where stable specifications, routine supply, and purchasing efficiency matter as much as the material itself. Compared with lower grades, it provides better effective content and more stable industrial performance, while remaining more economical than higher-purity products.
As a synthetic material made from silicon and carbon, silicon carbide is known for its:
- high hardness
- good wear resistance
- high temperature resistance
- relatively good thermal conductivity
- strong chemical stability
Because of these properties, Silicon Carbide 75% is widely used in industrial processes where practical performance and raw material cost need to be balanced.
We support bulk orders, multiple particle sizes, customized packing, third-party inspection, and fast delivery, helping customers improve sourcing efficiency and production planning.

Industrial Applications of 70% Silicon Carbide
In actual production, 75% silicon carbide is mainly applied in the following fields:
Foundry Applications
75% silicon carbide is widely used in the foundry production field, particularly suitable for scenarios seeking a balance between performance and cost. Compared to the 65% grade, the effective SiC content of the 75% grade increases by about 10 percentage points, capable of providing a more stable graphitization promotion effect. In the production of gray cast iron and ductile iron, adding 75% silicon carbide at a ratio of 0.3%-0.8% of the molten iron weight can significantly reduce the chilling tendency (white iron tendency), keep the hardness fluctuation range of castings within HB 20, simultaneously improve machinability, and extend tool service life by about 15%-20%. For foundry enterprises pursuing reliable daily production support, this grade is an economical and stable choice.
Metallurgical Applications
In the metallurgical field, 75% silicon carbide can meet buyers' needs for practical industrial value, without the need to switch to higher-cost premium grades (such as 85% or 90% and above). Its typical deoxidation efficiency can reach 75%-85%. Adding 3-6 kilograms per ton of molten steel in electric furnace steelmaking can effectively reduce the total oxygen content in molten steel by about 30%-40%. This grade of product is particularly suitable for production operations that focus on cost control while requiring stable specifications (e.g., SiC content fluctuation ≤±2%, particle size distribution deviation ≤5%). Compared to 98% high-purity silicon carbide, the 75% grade can save users about 25%-35% in material procurement costs.
Refractory Production
In the refractory manufacturing field, 75% silicon carbide can be used in various formulations that are cost-sensitive but require a certain SiC content. For example, in iron runner castables, taphole clay, and blast furnace ceramic cup materials, adding 75% silicon carbide at 10%-25% of the total aggregate can significantly improve the material's resistance to slag corrosion (corrosion rate reduced by about 20%-30%) and thermal shock resistance (thermal shock cycles increased to over 15 times). For refractory products with non-extreme operating conditions and no need for high-purity silicon carbide, using the 75% grade can reduce formulation raw material costs by about 15%-20% while meeting service life requirements (e.g., the iron throughput of the iron runner reaches 100,000 to 150,000 tons).
General Industrial Applications
In broader industrial application fields, 75% silicon carbide offers bulk supply and fast delivery services. Regular inventory particle sizes include: 0-1mm, 1-3mm, 3-5mm, 5-8mm, and 200-mesh fine powder, which can meet the needs of different industries such as abrasives, ceramics, and wear-resistant coatings. The company has the capacity to supply over 200 tons in a single batch, and regular orders can be produced and shipped within 7-15 working days. For customers who require stable material supply, flexible particle size selection, and highly responsive logistics support in their daily production, this grade provides an ideal solution that balances performance and supply efficiency.
