🏭 Manufacturing Process

Our high purity aluminum granules are produced through the following stages:

Raw Material Selection – High-grade aluminum ingots are selected and verified for purity.
Melting – Aluminum is melted in a controlled atmosphere to prevent contamination.
Granulation – Using centrifugal or gas-atomization methods, molten aluminum is formed into custom particle sizes aluminum granules.
Cooling & Solidification – Rapid cooling ensures uniform structure and minimizes oxidation.
Screening & Sorting – Granules are sieved into specific size ranges.
Quality Inspection – Each batch is tested for purity, size uniformity, and moisture content.

🔬 Applications

1️⃣ Laboratory Aluminum Granules

Ideal for material science research, thermal conductivity experiments, and metallurgical studies. Their high purity ensures repeatable and accurate results in laboratory conditions.

2️⃣ Metallurgy Aluminum Granules

Essential in alloy manufacturing, where aluminum granules 99.9% are added to molten metals to adjust composition, improve corrosion resistance, and enhance mechanical strength.

3️⃣ Pure Aluminum Granules for Coatings

Widely used in vacuum evaporation coating for optics, electronics, and decorative finishes due to aluminum’s excellent reflectivity and low density.

4️⃣ Alloying Additives

High purity aluminum granules are used to refine grain structure, improve castability, and reduce defects in specialized alloys such as aluminum-bronze or Al-Mg systems.

5️⃣ Custom Particle Sizes Aluminum Granules

We supply granules in sizes tailored to customer needs—from ultra-fine particles for precise chemical reactions to larger pellets for bulk alloying.

💡 Advantages Over Other Aluminum Forms

✅ No Need for Additional Refining – Purity at 99.9% eliminates costly refining steps.
✅ Ease of Handling – Granular form is easier to measure, transport, and store than ingots or powder.
✅ Reduced Oxidation Risk – Smaller surface area per volume reduces exposure to air.
✅ Customizable Sizes – From 0.5 mm to 10 mm or more, meeting specific industrial demands.
✅ Consistent Quality – Each granule batch is homogeneous in composition.
