When you need to buy calcium silicon wire for sale, quality and consistency are non-negotiable. Calcium silicon core wire (CaSi wire) plays a critical role in modern steelmaking, particularly during ladle injection for inclusion modification and sulfur control.
If your mill is looking for a dependable source of calcium silicon cored wire, you’ve come to the right place. We supply high-purity CaSi wire for both domestic and international buyers, with flexible packaging and shipping options.
In secondary steel refining, adding calcium directly into molten steel improves castability and reduces nozzle clogging. However, direct addition is inefficient. That’s why most plants switch to cored wire injection.
With CaSi wire, you get:
Deeper and more precise calcium delivery
Higher recovery rate (typically 20–30% better than lump addition)
Faster reaction time
Cleaner steel with fewer oxide inclusions
Steel mills, foundries, and investment casting plants all rely on calcium silicon core wire to produce high-grade grades like bearing steel, tire cord, and pipeline steel.
Our calcium silicon wire for sale meets international standards. Each batch is tested for chemical composition, powder weight, and mechanical strength.
Parameter | Details |
|---|---|
Core powder | Ca 28–32%, Si 55–65%, Ca+Si ≥ 85% |
Powder weight | 210–230 g/m (customizable) |
Strip material | Mild steel (0.35–0.45 mm thickness) |
Outer diameter | 13 mm ± 0.5 mm |
Coil weight | 1 – 1.2 tons (or as requested) |
Spool type | Hexagonal or square arbors |
Need a different chemistry? We also produce CaSi wire with higher calcium (30–33%) or lower silicon content. Just send your target range.
Unlike many suppliers who only focus on price, we focus on injection performance. Here’s what buyers notice after switching to our calcium silicon cored wire:
Uniform powder filling – no gaps or clumps along the wire length
Strong steel sheath – resists breakage during uncoiling and feeding
Consistent diameter – fits standard wire feeders without jamming
Dry packaging – sealed against moisture to prevent hydrogen pickup
These details might look small, but they directly affect your calcium yield and process stability.
Purchasing CaSi core wire internationally is straightforward when you work with an experienced exporter. Here’s our typical process:
Inquiry – Tell us your monthly or quarterly consumption. Also share your target calcium recovery rate if known.
Sample test – We ship a small coil (100–200 kg) for your plant trial.
Commercial order – Confirm quantity, payment terms (L/C, T/T), and delivery port.
Production – Lead time is usually 15–20 days for 20–50 tons.
Shipping – By container (20 ft or 40 ft) or bulk vessel, with fumigated wooden spools.
We have shipped to major steelmaking regions including Southeast Asia, the Middle East, South America, Europe, and Africa.
While ladle refining is the main use, our calcium silicon wire for sale also serves:
Ductile iron production (nodularizer addition)
Non-ferrous alloys (calcium treatment)
Specialty foundry work requiring deep deoxidation
If your process uses a wire feeder, there’s a good chance CaSi wire will improve your results compared to pure calcium or CaFe.
Hongsun is not a trading company with multiple middlemen. We work directly with a qualified alloy plant that has produced calcium silicon cored wire for over a decade. This direct control gives us:
Lower price – No extra markup layers
Custom chemistry – We adjust powder mix without charging tooling fees
Traceability – Every coil has a heat number and an inspection certificate
After-sales support – If you face feeding issues, we help troubleshoot
We understand that when you buy calcium silicon wire for sale, you need more than just a product – you need a partner who ensures your steel quality stays consistent across heats.
To protect the wire during ocean freight, we use:
VCI anti-rust paper between layers
Plastic wrap over each coil
Steel strapping to prevent shifting
Labeling with net weight, batch number, and Ca/Si content
Standard spools fit most wire feeders from Danieli, Concast, or SMS group. If you use a non-standard arbor, we can adjust the spool core size.
Q: What’s the minimum order quantity for CaSi wire?
A: For export, the smallest trial order is 5 tons (4–5 coils). For regular buyers, 20 tons is the most economical.
Q: Can you provide a mill certificate?
A: Yes. Every shipment includes a certified analysis report from an ISO 9001:2015 facility.
Q: How long does shipping take to my country?
A: From China, 25–35 days to most Asian ports, 35–45 days to Europe, and 40–50 days to South America.
Q: Do you offer CaSi wire with a thinner sheath for higher feeding speed?
A: Yes, we can adjust the sheath thickness from 0.35 mm down to 0.30 mm. Let us know your feeder type.
