High Leaded Tin Bronze -- CDA: C93200
from Concast Metal Products Co.

The alloys which are described as tin bronzes have long been recognized for their low lead content (less than .25% lead) and high strength characteristics. These alloys from C90200 through C91700 are not materially different than those produced more than 3,500 years ago in Europe and China. These... [See More]
