Aluminium in mechanical engineering

Aluminium is a versatile and lightweight material that is very popular in mechanical engineering due to its high strength and resistance to corrosion. It is easy to process and shape, making it an ideal choice for complex and precise components. It is also an environmentally friendly material that is 100% recyclable, contributing to sustainable production.
BWB refines aluminium components with electrolytic, chemical and galvanic surface coatings, which additionally protect them against abrasion and corrosion.
