Titanium-copper composite bar performance: titanium copper composite rod as a metal anode of the main components, its role has the following three points:
A: support the anode; titanium copper composite rod has a certain strength and bending resistance, composite bar yield strength of 128MPa, fully meet the production design requirements.
Two: excellent conductivity; the use of explosion + rolling production process so that titanium can be completely close composite, does not produce delamination and therefore has good electrical conductivity, composite strength of 135Mpa, and micro resistance of 7.77 × 10-6Ω.
Three: corrosion resistance, titanium copper composite bar directly with the outer layer of contact with the electrolyte, the outer layer of titanium has excellent corrosion resistance (see table), its life than other materials electrode 10 times longer.
