Calcium Alloys

we specialize in the production of high-quality Calcium Alloys. Manufactured using advanced technology and premium raw materials, our alloys ensure excellent performance and consistency. We follow strict quality control measures at every stage to maintain reliability. Each batch is carefully packed and dispatched to preserve its quality.

Ingredients / Composition

Calcium alloys are made by combining calcium (Ca) with other metals to enhance specific material properties. Calcium is typically used in small percentages due to its reactivity and role as a modifier or additive.

Common Calcium Alloys:

  1. Calcium-Aluminum Alloy (Ca-Al)

    • Calcium: 10–30%

    • Aluminum: Balance

  2. Calcium-Silicon Alloy (Ca-Si)

    • Calcium: 30–35%

    • Silicon: 55–60%

    • Iron or aluminum may be added

  3. Calcium-Lead Alloy (Ca-Pb)

    • Calcium: <1%

    • Lead: Balance

  4. Calcium-Magnesium Alloy (Ca-Mg)

    • Calcium: 1–2%

    • Magnesium: Balance

FAQ

1. What is the role of calcium in steelmaking?

+
Calcium improves steel quality by removing oxygen, sulfur, and impurities during refining, leading to better surface finish and mechanical strength.

2. Why is calcium added to aluminum alloys?

+
In aluminum, calcium enhances castability, modifies grain structure, and can improve resistance to hot cracking.

3. How is calcium used in lead-acid batteries?

+
Calcium-lead alloys are used in battery grids to increase strength, reduce water loss, and extend battery life.

4. Can calcium alloys be used in lightweight metals?

+
Yes. Calcium is often added to magnesium alloys for structural applications requiring both low weight and high corrosion resistance.

5. Is calcium used in the electronics industry?

+
Indirectly. Calcium-containing alloys like Ca-Si may be involved in producing semiconductor-grade silicon by purifying metallurgical-grade silicon.
