On average, pure and high purity ingot - cast as sow and
standard ingots - accounts for about 6 per cent of DUBAL's total
annual production output (2010: 13.4 per cent). Superior processing
and performance standards ensure that purity levels of up to 99.98
per cent are maintained and that customers' exacting expectations
are constantly met. Utilized in electronic and aerospace
applications, where top quality high purity aluminium is critical
to the successful manufacture of precision instruments,
DUBAL's high purity aluminium products are used in the manufacture
of compact discs, computer hard drive memory disks, capacitors and
other electronic components. It is also used in the manufacture of
high reflectance, high performance alloys and cathodic
protection.
