Leaded / Free Machining Nonferrous Metals and Alloys

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]

C31400 Leaded Commercial Bronze -- Hex
from National Bronze & Metals Inc.

C31400 Leaded Commercial Bronze ASTM B140. Leaded Commercial Bronze C31400 combines the natural corrosion resistance of C22000 with the machinability typical of leaded brasses. Like C22000, it is an alpha brass nominally composed of 89% copper and 9% zinc, but it also contains approximately 2% lead... [See More]
