We have been given a worn out sample of Worm Wheel for manufacture of a new one.
We drew borings from the sample (made in Sweden) for chemical analysis and the following
results were found:
Copper: 68.20%, Tin: 11.36%, Zinc: 20.44%, Lead: Trace, Phosphorus: Trace, Nickel: Trace,
Aluminium: Nil, Manganese: Nil, Iron: 0.30%.
We are unable to trace the relevant standard & grade to which this bronze belongs,
without which we cannot get the percentage range of each element.
Any help shall be highly appreciated. Kindly e-mail your views at calicut@hotmail.com & oblige.
