White Metal Alloys
DKL Metals manufacture a wide-range of tin and lead-based, white metal bearing alloys to meet all recognised national and international standards. We also offer a custom alloy manufacturing service based on your specific requirements or on metal samples submitted for analysis by our in-house laboratory. There are many white metal alloys in use today, so we have detailed below a selection of guide specifications based on the BS3332 1987 range.
