For many global buyers – especially those in steel desulfurization, long-term storage, or large-scale acetylene generation – the calcium carbide 50-80mm size is the optimal choice. Our factory produces this specific grade with strict screening controls, ensuring calcium carbide 50 80mm consistent dimensions, low dust content, and superior performance.

Calcium carbide 50-80mm Stands Out

Larger calcium carbide 50-80mm have advantages over smaller or mixed-size products:

Lower Dust Generation – Fine particles make handling losses, and waste material. Our calcium carbide 50 80mm contain minimal dust, than the small size

Container-Friendly – This size packs efficiently into 50kg steel drums or 100kg steel drums without excessive void space. It also withstands stacking pressure without crumbling.

Best Applications for Calcium Carbide 50 80mm

Steel desulfurization – larger lumps feed steadily into injection systems

Open-top acetylene generators – where slow reaction is preferred

Long-distance export – to high-humidity destinations (Southeast Asia, Africa, South America)

On-site gas production – for welding, cutting, and metal fabrication

Factory-Direct Quality You Can Trust

We produce our calcium carbide 50 80mm from high-grade lime and anthracite in closed furnaces. Every batch is tested for:

Gas yield: 295–305 L/kg

Phosphorus content: ≤0.06%

Sulfur content: ≤0.08%

Dust percentage: ≤3%

Packaging options include nitrogen-sealed steel new drums and palletized containers. We also provide SGS/BV factopry inspection.

The Best Choice

Our calcium carbide 50 80mm grade delivers nearly 100% usable material. When you calculate cost per effective kilogram, the larger size frequently proves more economical.
