Material
Brass C485 (High-Leaded Naval Brass)
Brass C485, also known as high-leaded naval brass, is a tin-bearing brass with added lead. The tin gives it seawater corrosion resistance comparable to Brass C464, while the lead makes it a common choice for machined parts.

About
Brass C485 (high-leaded naval brass) contains about 60% copper, 37.5% zinc, 1.8% lead and 0.7% tin.
Like Brass C464, its tin content improves resistance to seawater corrosion and dezincification, and it resists wear, fatigue, galling and stress corrosion cracking. The lead addition makes it better suited to machined parts than C464. Because of the lead, it can be soldered or brazed but not welded.
Typical parts include marine hardware, valve stems, fasteners, light bearings, gears and screw-machine parts.
