Aluminum: Properties and Significance

• Appearance: Bright silver-white metal

• Melting Point: ~1,220°F (660°C)

• Density: 2.7 g/cm³

• Abundance: ~8.1% of Earth’s crust, the most common metal element

• Key Advantages: Lightweight, corrosion-resistant, recyclable, and easy to alloy

One of aluminum’s most unique qualities is its natural oxide layer, which forms instantly when exposed to air. Therefore, aluminum resists corrosion and gains long-term durability. Consequently, it has become vital for aerospace, automotive, and outdoor construction projects.

Common Aluminum Processes in Vietnam

Aluminum Casting

Casting involves pouring molten aluminum into molds to form complex shapes.

This process is widely used for windows, doors, facades, solar panel frames, and machinery. In addition, extrusions can be anodized, polished, or powder coated for better durability and appearance.

VNO Insight: With demand rising in construction and renewable energy, Vietnamese aluminum extrusion suppliers have become reliable partners for buyers who value flexibility and competitive pricing.

Aluminum Rolling

Rolling converts aluminum into sheets, plates, or foils for broad applications.

• Aluminum Cold rolling produces thin, smooth sheets for packaging and consumer products.

• Aluminum Hot rolling creates thicker plates for shipbuilding and aerospace.

As a result, aluminum rolling serves industries ranging from household foil to aircraft fuselages.

Surface Finishing

Surface finishing improves both performance and design.

• Aluminum Anodizing adds a corrosion-resistant, durable, and colored layer.

• Aluminum Polishing and brushed aluminum improve appearance, especially in consumer products.

• Powder coating combines protection with decorative finishes.

Therefore, finishing techniques are highly valued in architecture, electronics, and premium consumer markets.

Joining and Fabrication

Aluminum is easy to shape and assemble using several methods:

• Aluminum Welding requires skilled handling because of the oxide layer and high conductivity.

• Aluminum Brazing bonds parts with filler metal without melting the base aluminum.

• Cutting uses CNC machining, laser systems, or saws for precision.

Consequently, these processes are critical for automotive, aerospace, and medical equipment.

Why Aluminum Matters in Global Supply Chains

Aluminum supports modern manufacturing for four key reasons:

• Lightweight – Improves fuel efficiency in vehicles and aircraft.

• Durability – Resists corrosion in harsh environments.

• Recyclability – Needs only 5% of the energy used in primary production, aligning with ESG goals.

• Versatility – Works across casting, extrusion, rolling, and machining.

For international buyers, understanding aluminum processing methods leads to smarter supplier choices, better quality control, and cost savings. With the rapid growth of aluminum in Vietnam, buyers benefit from a market that blends advanced capacity with competitive pricing.

Vietnam’s Role in Aluminum Processing

Vietnam is fast becoming a hub for aluminum manufacturing. Compared to China and India, it provides several advantages:

• Lower Costs – 10–20% cheaper than China for small and medium orders.

• Skilled Workforce – Expertise in extrusion, die casting, and machining.

• Export Standards – Factories follow ISO 9001, ASTM, RoHS, and REACH.

• Diverse Capabilities – From aerospace-grade alloys (7075 T6) to construction profiles.

At VNO, we connect U.S. and EU clients with certified Vietnamese aluminum factories. Therefore, buyers secure compliance, consistent quality, and long-term partnerships.
