Zinc vs. aluminum

When choosing the right material, the focus is often on zinc and aluminum. Both metals have their strengths and are used in many areas. However, zinc offers decisive advantages that make it particularly attractive for demanding projects.

Corrosion resistance

Zinc forms a natural patina that protects the material from corrosion and has a self-healing effect. Aluminum is also protected by an oxide layer, but is more susceptible to damage.
 

Durability

Zinc has an impressive service life of up to 100 years, especially outdoors. Aluminum has a shorter lifespan, especially in aggressive environments.
 

Environmentally friendly

Zinc is 100% recyclable and requires less energy to produce. Aluminum is also recyclable, but requires more energy.
 

Aesthetics

Zinc develops an elegant, blue-grey patina that gives an attractive appearance over time. Aluminum remains color-stable, but offers fewer visual changes.

 

Conclusion: Zinc scores points for better corrosion resistance, durability and sustainability, especially outdoors.
