Copper No. C11000
Electrolytic Tough Pitch Copper
CDA 110 ETP Copper , ASTM B 187 , ASTM
B 152
Nominal Chemical Composition % by
weight
Material Properties
Hard drawn bus bar with high thermal and electrical
conductivity. Good resistance and tampering. Not suitable for case
hardening.
Applications
Copper No. 11000 is used for welding fixtures, anodes, bus
bar in electrical power installations, ground straps, commutators, etc. Its
inherent fabrication qualities readily permit it to be bent, soldered,
drilled, peened, riveted and formed to fit almost any design specification.
Mechanical Properties
Typical for 1" solid diameter Hard
(35%) Temper
