Chromium-zirconium copper characteristics: With good electrical and thermal conductivity, high hardness, wear resistance, knock resistance, crack resistance and softening temperature,Less loss in use, low total welding cost, suitable for welding machine electrode and related parts. Main uses: Butt welding wheel, conductive block, electrode cap, carbon dioxide protection nozzle, conductive nozzle, various specifications of electrode wheel; Spot welding of electrical switches, electronic components, tubes, electron guns and picture tube housings. Chromium-zirconium copper has the following characteristics compared to beryllium copper: 1, high stress relaxation resistance, good thermal stability, wide aging range, high yield can be used at high temperatures for a long time (100° C -250 ° C). Upright performance is preferred. 2, good electrical conductivity, 75%IACS 3, good corrosion resistance. 4. Good electroplating performance. 5, environmental protection, suitable for sanitary ware mold, food mold. Chrome zirconium copper application: This product is widely used in automobile, motorcycle, barrel (can) and other machinery manufacturing industry welding, conductive nozzle, switch contact, mold block, welding machine auxiliary devices for various materials. How to remove the oxide on the surface of chrome-zirconium copper? ①strong corrosion: industrial sulfuric acid 50-60, industrial hydrochloric acid 1, tap water 40-50. Temperature: room temperature. Time: 2-10 minutes. ②weak corrosion: industrial sulfuric acid 10, tap water 90. Temperature: room temperature. Time: 2-10 minutes. ③Wash. ④ passivation: industrial sulfuric acid 5-10 parts, chromium trioxide 5-10 parts, tap water 80-90 parts. Temperature: room temperature. Time: 2-10 minutes. ⑤washing - flow washing - deion washing - drying. Why is chrome-zirconium copper used for resistance welding electrodes? Chromium zirconium copper through thermal treatment and cold processing connected system method to guarantee the function, it can obtain the best mechanical function and physical function, so used to do common use resistance welding electrode, mainly as spot welding or seam welding low carbon steel, coated steel electrode, can also be used as welding low carbon steel electrode grip rod, shaft and liner information. Or as the electrode grip rod, shaft and liner material for welding low carbon steel, or as a large mold, fixture, stainless steel and heat-resistant steel mold or embedded electrode for convex welding machine. Chrome zirconium copper use precautions: Chrome copper, chrome zirconium copper processing precautions 1. Chromium copper, chromium zirconium copper is easy to produce oxidation phenomenon after processing, pay attention to timely anti-rust protection after processing. 2. Chromium copper, chromium zirconium copper has good processing properties, lathes, grinding machines, milling machines, stamping and other processing equipment can be processed. 3. Chromium-copper, chromium-zirconium copper alloy is non-magnetic, please confirm that the product has been firmly fixed before operation. Precautions for welding chromium copper and chromium zirconium copper When welding chrome copper, chrome zirconium copper, pay attention to the temperature should not be too high, high temperature operation will lead to hardness and conductivity defects. Chrome copper, chrome zirconium copper Other precautions 1. The appearance of chromium zirconium copper and other copper alloy materials are not obvious, please distinguish the processing. 2. Chromium copper, chromium zirconium copper has good plating ability. 3. Chromium copper, chromium zirconium copper can be very good and other materials for brazing, gas welding operations. 4. As a resistance welding electrode, please select the electrode material reasonably according to the material and thickness of the workpiece to be welded. 5. The aging process is different, which will lead to the different surface color of chromium copper and chromium zirconium copper, and does not affect the performance of chromium copper and chromium zirconium copper. 6. Other unknown matters. |
