High electrical and thermal conductivity, good corrosion resistance and solderability. C11000 is used for welding fixtures, anodes, bus bar in electrical power installations, ground straps, commutators and current carrying hardware. Its inherent fabrication qualities readily permit it to be bent, soldered, drilled, peened, riveted and formed to fit almost any design specification. This beryllium copper has excellent hot workability.

PB1 or Phosphor bronze is an alloy comprised of tin and copper that has also had phosphorus added to it during the casting process.
The main benefits of phosphor bronze are that is has a good resistance to cold and corrosion, (approaching that of aluminium bronze) as well as both an excellent mechanical strength and high fatigue strength.
PB1 is a single phase alloy that is suitable for cold working and its good corrosion resistance to sea water and brine make it well suited to for both pump and valve components.
It is also suited for applications such as heavy load gears, worm wheels and bearings that have medium to high loads as well as speeds.
Phosphor bronze also has good resistance to impact loading and pounding. In order to use PB1 in these applications the metal must have good lubrication and alignment.
