Product Description

DIN 2.1293 Copper Chromium Zirconium Round Bars For Resistance Welding Electrodes

Description of Copper Chromium Zirconium:

Used extensively for cap style resistance welding electrodes.

Evidence suggests that it can provide less sticking and resist deformation longer than

its copper-chrome counterpart in some specific situations.


Physical Properties:

Density at 68°F: 0.321 Lbs./In.3
Specific Gravity: 8.89
Melting Point: (Liquidus): 1080°C (1976°F)
  (Solidus): 1070°C (195°F)
Coefficient of Thermal Expansion per °F: 9.5 x 10-6 (77-212°F)
Electrical Conductivity at 68°F (volumetric): 80% IACS (aged and drawn)
Thermal Conductivity Btu/ft.2/ft./hr./°F at 68°F: 187
Modulus of Elasticity - Tension: 17000 ksi


Equivalent Specifications:



DIN 2.1293

ASTM C18150
