Based on the latest market data as of early 2026, below are some of the leading names in Vietnam’s aluminum manufacturing and copper wire export industry.

These companies not only dominate the domestic market but also possess strong export capabilities to demanding markets such as the United States, the EU, Japan, and South Korea.

1. Leading Companies In Vietnam’s Aluminum Industry

Vietnam’s aluminum industry has made significant progress in extrusion and casting technologies, with several standout manufacturers:

Dinostar Aluminum (Ngoc Diep Group)

One of the fastest-growing companies in the industry, recognized in the VNR500 ranking in 2025. Dinostar operates a modern manufacturing facility in Hung Yen Province, specializing in the export of aluminum billets, ingots, and extrusion profiles to the U.S. and European markets.

DongA Aluminum

Located in Hai Duong Province, DongA Aluminum is one of the largest aluminum exporters in Northern Vietnam, known for industrial and construction aluminum profiles supplied to international markets.

Grando Aluminum

Considered part of Vietnam’s “Big 5” aluminum manufacturers, Grando operates German and Swiss production lines with an annual export capacity of tens of thousands of tons.

Tungshin Aluminum

A Taiwan-invested FDI company based in Binh Duong, Tungshin is one of the industry’s long-established exporters of aluminum extrusion products worldwide.

Hoa Phat Aluminum

Although relatively new to the aluminum sector compared to its steel business, Hoa Phat is rapidly expanding its export market share in both household and industrial aluminum products thanks to its strong financial capacity.

2. Leading Copper Wire & Electrical Cable Manufacturers

Vietnam plays an increasingly important role in the global electrical equipment supply chain, supported by several key manufacturers:

CADIVI (Vietnam Electric Cable Corporation)

Widely regarded as the leading brand in Vietnam’s electrical cable industry. CADIVI’s copper wire products meet strict international standards and are exported extensively to the U.S., Australia, and Southeast Asian countries.

ThiPha Cable

Currently owned by Stark Corporation (Thailand), ThiPha is one of Viet Nam’s leading exporters of copper and aluminum cables for energy and infrastructure projects across regional and international markets.

CADI-SUN

One of the largest private manufacturers in Northern Viet Nam specializing in copper wire and electrical cables, with a stable export network throughout Asian markets.

SACOM (SAM Wires & Cables)

Specializes in magnet wires and high-precision copper wire products for electronic component manufacturing, supplying major production chains in Japan and South Korea.

LS-VINA Cable & System

A joint venture between LS Group (South Korea) and Viet Nam, specializing in underground cables and high-voltage copper cable systems for large-scale global infrastructure projects.

3. Export Trends 2025 – 2026

Green Certifications & Sustainable Manufacturing

Companies such as Dinostar and CADIVI are increasingly focusing on green manufacturing solutions — including recycled aluminum and low-emission copper production — to comply with carbon border regulations such as the EU’s CBAM policies.

Market Diversification

While the U.S. remains the largest export market, Vietnamese manufacturers are also leveraging trade agreements such as CPTPP and EVFTA to expand aluminum profile and electrical cable exports into Japan and Nordic countries

If you are seeking reliable manufacturing partners for industrial sourcing, production supply, or international export operations, these companies are currently among the most reputable names in Viet Nam in terms of production capability and international quality standards

Vietnam’s aluminum processing and electrical cable export industry is undergoing a major transformation in 2026 to adapt to increasingly strict technical barriers and sustainability standards from global markets, especially the European Union and the United States.

Below are the key trends currently shaping the industry:

1. The Rise Of “Energy Aluminum” & Lightweight Alloys

Vietnam’s aluminum sector is no longer focused solely on traditional construction aluminum. Manufacturers are shifting toward high-value technical aluminum products that support the global green economy.

Aluminum Alloys For Electric Vehicles (EVs)

Vietnamese manufacturers are increasingly processing aluminum components such as battery casings (5052 aluminum), structural vehicle frames (6061, 7075), and heat dissipation systems. This segment is expected to achieve an annual growth rate of approximately 28%.

Aluminum For Renewable Energy

Production of aluminum frames for solar panels and support structures for wind turbines (mainly 6063 and 1050 alloys) is growing rapidly. These products are fully recyclable and aligned with circular economy standards.

Low-Carbon & Recycled Aluminum

Manufacturers are increasingly using recycled aluminum billets and low-carbon production methods to reduce carbon footprints and comply with carbon taxation policies in international markets.

2. Green-Standard Electrical Cables & Power Infrastructure

In the electrical cable sector, manufacturing trends are focusing on performance, durability, and sustainability for harsh operating environments.

Offshore Wind Power Cables

These products require advanced processing technologies with high resistance to saltwater corrosion and extreme pressure conditions. This high-value segment is becoming a major target for companies such as LS-VINA and ThiPha Cable.

EV Charging Cables

Vietnamese manufacturers are expanding into flexible, heat-resistant charging cable systems integrated with smart data communication technologies for electric vehicle infrastructure.

Eco-Friendly Insulation Materials

Traditional PVC insulation is gradually being replaced by halogen-free materials to reduce toxic emissions during fires and improve recyclability.

3. Adapting To The Carbon Border Adjustment Mechanism (CBAM)

Starting from 2026, the European Union is fully implementing the Carbon Border Adjustment Mechanism (CBAM), requiring aluminum and steel-related products to declare and pay carbon-related taxes.

This has triggered two major industry shifts:

Digital Transformation & Traceability

Manufacturers are investing heavily in ERP and traceability systems to provide transparent emission data for every processed product unit.

Renewable Energy Adoption

Factories producing aluminum and electrical cables are rapidly installing rooftop solar systems and entering renewable energy purchasing agreements (PPA) to reduce actual emission intensity.

4. Transition From Pure OEM Processing To Integrated Manufacturing

Rather than simply processing aluminum billets or manufacturing cables based on client designs, Vietnamese companies are increasingly moving toward higher-value production models.

ODM Manufacturing & Engineering

Manufacturers are beginning to design intelligent aluminum profile systems and integrated cable solutions for green buildings and sustainable infrastructure projects.

High-Precision Processing

Advanced 5-axis CNC machining technologies are being adopted to manufacture complex aluminum components for aerospace and medical industries, where profit margins are significantly higher than traditional construction materials.

Conclusion

“Green transformation” is no longer optional — it has become a mandatory requirement for survival in the global supply chain.

Companies capable of mastering aluminum recycling technologies, low-carbon production, and transparent emissions reporting will hold a significant competitive advantage in the international market throughout 2026 and beyond.
