Improved our technical skill and production facilities guarantee high quality of our product EK-METALS.
MATERIAL EK-2
With durability improved by
adding special element to copper
chromium-zir conium alloy, it
excells in electric conductivity
and heat resistance;hence, it is
in use most widely as resistance
welding electrode material.
MATERIAL EK-3
Having excellent mechanical strength
of copper-chromium-titanium
alloy, EK-3 is suited to the electrode
materials working raised welding
ressure where very high strength and
durability are required.
MATERIAL EKB-50
Having the most excellent strength,
wear resistance and thermal
durability of the berylium-copper
50 alloy made by adding some
special elements to copper berylium
base alloy, EKB-50 proves it' s
merits in the applications to flush
butt and seam welding electrodes
or holder of welder operting under
very severe working enviroment.
MATERIAL CZ-5
Having a high copper-chromium-
zirconium content, it' s
high-temperature strength is best
suited for seam welding electrode
in particular, the surface treated
steel plate resistant welding is
being used.
