Commercial-Scale Cost Savings: Outperforming retail options like calcium carbide bunnings in unit price, our factory-direct bulk supply offers substantial wholesale discounts for long-term contract procurement.
Large Lump Granulation (80-120mm): Specially sized for heavy-duty acetylene generators and ladle desulfurization, offering a slower, prolonged reaction rate and steady gas flow.
High Gas Yield Guarantee: Premium grade material yielding ≥295 L/kg - 305 L/kg of high-purity acetylene gas at standard temperature and pressure.
Strict Impurity Control: Maintained phosphine (PH3≤0.08%) and hydrogen sulfide (H2S≤0.10%) limits protect downstream purification systems and extend equipment lifespan.
Heavy-Duty Export Packaging: Packed in UN-approved 50kg or 100kg iron drums with nitrogen (N2) purging to ensure safe transit and zero moisture intrusion.
For industrial facilities, chemical manufacturers, and steel foundries seeking a dependable commercial supplier beyond retail hardware stores, our high-purity 80-120mm Calcium Carbide (CaC2) offers a superior factory-direct alternative. While small-scale users often search for local retail options like calcium carbide bunnings for minor applications, commercial enterprise buyers require high volume, consistent gas yield, strict chemical purity, and bulk wholesale pricing that retail distributors simply cannot accommodate.
Our 80-120mm large lump Calcium Carbide is synthesized using top-grade lime and high-carbon anthracite in advanced electric arc furnaces. Specially screened for large-scale operations, this coarse size range provides a steady, prolonged acetylene reaction suitable for heavy industrial generators and metallurgical processing.

Purchasing small consumer quantities through retail vendors such as calcium carbide bunnings incurs steep retail markups and packaging premiums. Partnering with a direct factory supplier allows commercial buyers to order full container loads (FCL) at competitive wholesale FOB/CIF rates, significantly lowering procurement expenses per metric ton.
The 80-120mm large lump size features a smaller surface-area-to-volume ratio compared to smaller granules. This results in a controlled, long-lasting reaction rate during hydrolysis, making it ideal for large-capacity acetylene gas plants and continuous heavy-duty industrial burners that require stable operating pressure over extended cycles.
Unlike non-industrial grade chemical supplies found via calcium carbide bunnings consumer searches, our factory-manufactured material undergoes strict batch quality control. By limiting phosphine (PH3) and hydrogen sulfide (H2S) impurities to low percentages, our product minimizes catalytic contamination and extends the maintenance lifespan of downstream gas purifiers and piping systems.
Large-Capacity Acetylene Gas Plants: Acts as the primary chemical feedstock for high-volume acetylene gas generation used in commercial cutting, thermal joining, and heavy structural welding.
Steelmaking & Ladle Desulfurization: Applied as a powerful desulfurizing agent in iron foundries and steel mills to remove sulfur impurities from molten iron, enhancing steel toughness and tensile strength.
Deoxidizing Reagent: Used in electric arc furnace (EAF) steelmaking to refine slag composition and deoxidize molten metal baths.
Chemical Synthesis: Serves as a basic carbon feedstock for producing synthetic organic intermediates, calcium cyanamide, and specialty rubber compounds.
Calcium Carbide reacts vigorously with ambient humidity to generate flammable acetylene gas. To ensure complete safety during international ocean transport and extended warehouse storage:
Heavy-Gauge Steel Drums: Hermetically sealed inside brand-new 50kg or 100kg iron drums engineered to endure rough handling and atmospheric pressure shifts.
Nitrogen Purging Technology: Atmospheric oxygen and moisture are completely displaced by high-purity Nitrogen (N2) gas before sealing each drum.
Complete Regulatory Clearance: Every shipment includes comprehensive Certificate of Analysis (COA), Safety Data Sheets (SDS), UN Packaging Certificates, and SGS/BV pre-shipment inspection verification upon request.
