英文版:Electrode copper such as pure copper , chromium copper , chromium zirconium copper , beryllium copper , beryllium nickel copper , beryllium cobalt copper , wolfram copper , silver wolfram , brass , bronze , paktong , aluminium brass , leadless environmental protection brass , tellurium copper , silver copper 1. Pure pure copper characteristic property: High-purity , organization are detailed , oxygen content is extremely low. The nothing air hole , trachoma, are loose , the electric conduction function is extremely nice, the mould surface accuracy that the electricity erodes out is high , fight by that heat treatment handicraft , the electrode there being no directionality , being suitable to essence since, thin, the function and pure pure copper of Japan are well-balanced , price is more substantial, be that the head replacing entrance copper's chooses a product. 99.95% O <003 conductance rates ≥Cu ≥57 ms／m hardnesses ≥85.2 HV 2. Chromium copper characteristic property: The electric conduction heat conduction function is good , the high , able to endure antiknock of hardness, makes the electric conduction piece in common use. Up-right sex is good, since the flake is not curved. 3. Beryllium copper characteristic property: Beryllium copper is one kind of oversaturation solid solution copper base alloy , is mechanical performance , physics function, the chemistry function and coloured fine function union against corrosion alloy, classics is strengthened dissolving handling the day afer tomorrow with effectiveness for a given period of time , have the corresponding to special steel high strength limit , elastic limit, knuckle under the limit and the endurance limit. Have the have the high electric conduction rate , heat conduction rate , high hardness and abrasion resistance at the same time, high creep resistance and corrosion-resistance, apply to the mould of fabrication of all kinds broadly inlay a piece, the height making accuracy , complicated mould of form replacing steels, welding electrode material strikes machine , injection machine formed punch , the anti-corrosion able to endure job waits , beryllium Copperbelt applies to the micro-machine brush, hand electromechanical pool , computer connector assembly , switch contact of all kinds, Be that national economic construction is hit by essential important industry material on products such as spring clip, washer , diaphragm , the film small side door. Density 8.3 g／cm3 hardnesses 36-42HRC conductance rates ≥18% IACS tensile strengths ≥1000 Mpa heat conductions rate ≥105 w／m.k20 ~C 4. Wolfram copper characteristic property: The powder metallurgy makes specifically for wolfram steel , high-carbon steel , the thermostability surpass the hard alloy when the mould making requires an electricity to lose, the spoilage is big because of average electrode , speed is slow, wolfram copper is that a comparatively ideal material bending strength ≥667 Mpa
