Located in the heart of Kinshasa, Banza Aluminium stands as a trusted local manufacturer and supplier, deeply familiar with the needs of Congo’s diverse industries. We take pride in producing high-quality Aluminium 1070 Round Bars, crafted to support the growth and innovation driving our region forward. Our commitment is to provide reliable, readily available materials that meet the rigorous demands of our customers, ensuring their projects are built on a foundation of strength and local expertise.
When it comes to composition, Aluminium 1070 is about as close to pure aluminium as you can get, with a minimum of 99.7% aluminium content. This simple makeup gives these round bars excellent corrosion resistance and superior electrical conductivity. They are relatively soft and highly ductile, making them incredibly easy to work with for forming and machining, though they aren’t intended for high-strength structural applications.
