Hindustan Zinc Ltd, the world’s largest integrated zinc producer, has launched two next-generation zinc alloys, VedAZ and VedAyush, targeting the growing demand for specialised materials in the galvanising industry and other manufacturing sectors.
The new products are designed to improve manufacturing efficiency, coating consistency and the long-term performance of galvanised steel, strengthening the company’s value-added zinc products portfolio.
The launch comes against the backdrop of rising concerns over corrosion-related losses in India. According to a 2026 CII–Nomura Research Institute report, corrosion costs the Indian economy approximately 4.3% of its GDP annually. Improved corrosion protection and coating technologies are therefore becoming increasingly important for infrastructure, automotive, engineering and other industries dependent on galvanised steel.
Focus on expanding value-added zinc business
Hindustan Zinc aims to expand its presence in specialised zinc products by developing application-specific alloys to meet the requirements of downstream industries.
“Hindustan Zinc sees significant scope to grow its value-added zinc business across infrastructure, automotive, engineering and consumer products. Customers in these sectors need specialised grades tailored to their manufacturing processes and performance requirements. VedAZ and VedAyush broaden the range of needs we can address and create opportunities to build closer customer relationships,” said Hindustan Zinc CEO and Whole-time Director, Amarendu Prakash.
The company plans to leverage its integrated operations and alloy manufacturing capabilities to develop customised products, reach new customers and increase the contribution of value-added products to its overall portfolio.
VedAZ targets coating process efficiency
VedAZ is a specialised zinc-aluminium master alloy developed for the galvanising industry. It is designed to improve control over aluminium levels in galvanising baths, helping manufacturers maintain stable bath chemistry, achieve uniform coating thickness and improve surface finish.
Its optimised composition is also expected to reduce dross formation and zinc losses, enabling galvanisers to improve material utilisation and operational efficiency while maintaining consistent product quality.
VedAyush focuses on corrosion protection
VedAyush, a zinc-aluminium-magnesium alloy, has been developed to enhance corrosion resistance, coating adhesion and surface stability in demanding industrial environments.
The addition of magnesium is intended to improve the durability and performance of coated steel, particularly in applications exposed to high humidity, coastal conditions and challenging industrial environments.
The alloy is expected to find applications in infrastructure, automotive components, consumer appliances, power transmission and industrial systems, where longer-lasting corrosion protection is a key requirement.
30,000-tonne alloy manufacturing capacity
Hindustan Zinc, through its wholly owned subsidiary Hindustan Zinc Alloys Private Limited (HZAPL), operates a zinc alloy melting and casting facility with an annual capacity of 30,000 tonnes at Rajpura Dariba in Rajasthan.
The facility, supported by the parent company’s integrated operations, strengthens domestic availability of specialised zinc alloys and contributes to the development of a more resilient manufacturing supply chain.
The company’s existing specialised alloy portfolio also includes zinc die-casting grades HZDA-3 and HZDA-5. These products are designed for applications requiring castability, dimensional stability, mechanical strength, electrical conductivity and corrosion resistance, catering to automotive, electrical, industrial hardware and consumer product manufacturers.
HZDA-5 has received Bureau of Indian Standards (BIS) certification, complementing the certification already secured for HZDA-3.
With VedAZ and VedAyush, Hindustan Zinc is seeking to broaden its specialised zinc offerings and deepen engagement with galvanisers and downstream manufacturers as demand grows for durable, high-performance coated steel products.
