However, recent research and development practices have increased their corrosion resistance capacity to new heights, positioning zinc alloys as a leading material, capable of enduring the harshest of environments. These advancements have not only helped in the corrosion resistance property of zinc alloys, but have also significantly extended their service life, ensuring optimal performance in both favourable and challenging conditions.

Across the spectrum of zinc-based alloys, exceptional resistance to corrosion is a hallmark feature. This resilience makes zinc alloys indispensable in applications where exposure to corrosive elements is inevitable. Notably, the presence of aluminium in these alloys adds to their already robust corrosion resistance, further fortifying their suitability for a diverse array of environments. Whether exposed to road salts and harsh weather conditions when employed in automotive components, or atmospheric pollutants when utilized in structural elements of buildings, zinc alloys demonstrate unparalleled resilience, ensuring longevity and reliability. As industries continue to prioritize and value the durability of their products, the corrosion resistance of zinc alloys makes it one of its greatest assets, further helping it shape the landscape of modern engineering and construction practices.

• Customization

One of the most exciting advancements in zinc alloy technology is the capability to customize alloys according to specific application requirements. Through precise adjustments in composition and microstructure, engineers can tailor zinc alloys to yield desired properties like conductivity, thermal stability and resistance. This level of customization not only enhances the versatility of zinc alloys but also sparks innovation in product design. Manufacturers now have the freedom to create components that perfectly align with the demands of their respective industries, pushing the pre-existing boundaries present in the fields of engineering and design.

• Sustainable manufacturing

In the current climate of heightened environmental awareness, sustainability has become a primary consideration in the development of materials. Zinc alloys present numerous advantages in this context, which include their widespread availability, optimal recyclability and minimal energy consumption during processing. Recent initiatives have concentrated on enhancing the sustainability of zinc alloy production through the implementation of efficient recycling methods and the adoption of eco-friendly manufacturing processes. These efforts signify a commitment to reducing the environmental impact of zinc alloy manufacturing, further aligning with broader sustainability goals through responsible resource management.

Zinc is not only a metal used for die casting: first of all it is a natural occurring element that is essential for life and it is considered a “Life Saving Commodity” by the United Nations. Zinc indeed plays a fundamental role for our planet: it is vital for the natural development of biological processes of every living thing, such as cell division, protein synthesis, immune system and growth. It is therefore an essential element for life.

Furthermore zinc is highly recyclable, when it reaches the end of its life cycle it can indeed be recycled without losing any physical property, thus representing a new source of raw material. Approximatively 45% of available zinc at the end of life cycle is recovered and recycled; in Europe and in the United States this percentage reaches even 50%.

It is exactly this characteristic that is a key element for sustainability and development of a circular economy.

Zinc contributes to circular economy

Circular economy is an economic model based on waste reduction and on the development of a circular life cycle, at the end of which a product is no more considered a waste for disposal but is instead a new source of raw material. Zinc fits perfectly in this model: zinc life cycle indeed starts from mining, goes through refining process in order to be used in the modern society and ends with recycling stage at the end of its useful life. During this cycle zinc contributes in different ways to the well-being of our planet:

• It is highly recyclable, thus reducing need for new raw material and exploitation of natural resources

• It protects steel used for infrastructures and transport from corrosion extending the life cycle of steel products

• When used for coating steel it contributes to the reduction in CO₂ emissions

The countless areas of use of zinc and its excellent physical properties therefore confirm the great importance that zinc life cycle has for our planet. Here in Bruschi we are proud to use a highly sustainable material, essential for life and for the protection of the riches of our Earth.
