CDA 110 Electrolytic Tough Pitch copper is a soft, ductile, material
that offers outstanding electrical & thermal conductivity, excellent cold
formability, and fantastic corrosion resistance. Its inherent fabrication
qualities allow it to be bent, soldered, drilled, riveted, and formed to fit
almost any specification. Typical industrial uses include architecture,
automotive, building, electrical, fasteners, & stamping.

CDA 145 Tellurium Copper is used for forgings, screw machine parts
or any parts requiring high conductivity, extensive machining, and or
corrosion resistance. The addition of Tellurium results in short, clean
chips and allows for higher cutting speeds than that of pure copper,
with much less wear on tool life. Typical uses include electrical
connectors, motor or switch parts, plumbing fittings, welding torch tips,

CDA Beryllium Copper is the most universally used beryllium copper
alloy and is known to demonstrate higher strength and hardness when
compared to commercial copper alloys. It has strength and hardness
characteristics that are comparable to steel. It is also recognized as an
alloy that has outstanding wear & corrosion resistance, thermal fatigue,
and thermal conductivity. Typical applications are electrical switches and
connectors, fasteners, mold inserts, pump parts and valve seats.
