The more silver the silver electrode, the more common it is

【Summary Description】 Silver-containing copper electrode Is it true that the more silver the silver electrode, the more common it is? Silver electrode is generally copper-based, copper texture is relatively hard, with the increase of silver content of copper content decreased, it will become more and more soft, melting point is also reduced. I am from Zhongshan Huazhong Solder Co., Ltd. Copper electrode is a copper-zinc alloy, used for metal oxyacetylene flame brazing Phosphorus copper electrode is a kind of red copper containing phosphorus. Due to its good self-decontamination ability, good fluidity and wettability, it has been made into "silver-free electrode" instead of silver electrode for brazing of air conditioners and refrigerators. Silver welding rods are classified by their silver content. High silver content is used for welding jewelry, glasses, etc., and low silver content is used for brazing evaporators, condensers and other copper system parts of air conditioners, refrigerators. Can copper welding rod be burned with fire to lift silver It is a copper electrode and a silicon bronze electrode. White copper electrode with phosphor bronze electrode, high manganese aluminum bronze core and titanium calcium coating Minimum welding temperature of 25 silver copper zinc electrode 25 Silver Copper Zinc Welding Rod Melting Point-Centigrade. It is equivalent to American standard -6 and national standard, which has good fluidity and filling ability. It is widely used in air conditioning, refrigerator, mechanical and electrical industries, and brazing of copper and alloy. Melting Point-Centigrade., Containing 5% silver, which is equivalent to American Standard -3 National Standard, has certain plasticity and is suitable for welding copper and its alloy joints that cannot maintain close fit. The difference between silver electrode and copper electrode Choice: Both are acceptable. It also depends on the applicable environment of the welded workpiece, such as working temperature, whether it is subjected to greater force, etc. Contact the manufacturer for details and they will give you a comprehensive answer. The difference between phosphor copper electrode and silver copper electrode Phosphor copper electrodes and silver copper electrodes are different in chemical composition and strength after welding. 1. Different chemical composition Phosphor copper electrode composition is added phosphorus, silver copper electrode chemical composition is added silver. 2. Different strength after welding The post-weld strength of phosphor copper electrode is brittle, and the post-weld strength of silver copper electrode is higher than that of phosphor copper electrode. Phosphor copper electrode classification and composition 1. Composition P:7.5-8.5%, copper: balance. The melting temperature is-℃, the melting point is low, the solder has good fluidity, but it is relatively brittle. It is generally used for soldering copper and brass parts that are not subject to impact load and vibration. 2. (/BCuP-2): Composition P:6.80-7.50%, Copper: Balance. Melting temperature-℃, the solder has good fluidity and can flow into joints with small gaps, but the solder is brittle. It is generally used in the electromechanical and instrument industries to braze copper and brass parts that are not subject to impact loads. 1. Welding sequence In order to reduce the deformation of weldment when welding with copper electrode, when the length of welding gap is within mm, the straight-through welding method directly from one end to the other end can be adopted. If the length of welding seam is greater than mm, the welding can be carried out from the center to both ends. Some deformation prevention methods adopted for welding carbon steel can also be adopted when welding copper. 2. Welding current and electrode diameter The diameter of the copper electrode and the welding current are selected according to the thickness of the weldment, the beginning of the weld, the outer profile of the weldment and the heat dissipation conditions. Generally, the welding current is 40-50 times the diameter of the electrode. Encyclopedia-Copper Welding Rod Encyclopedia-Phosphor Copper Welding Rod
