What are the advantages of phosphor copper electrode than copper electrode?

【Summary Description】 Phosphor copper electrode What are the advantages of phosphor copper electrode than copper electrode? Compared with copper electrode, phosphor copper electrode has lower melting point, better wettability and fluidity, and is a good choice for working conditions with low brazing temperature requirements, and the price is not high. harris phosphor bronze electrode quality and stability, not a good choice in the industry. The general agent in China is Hebei Hart Welding materials Co., Ltd. phosphor copper electrode melting point is how much? Different types of phosphor copper electrode melting point is different, for example, as follows: 1. Melting temperature-℃, low melting point, 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): 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 mechanical and electrical and instrument industries to braze copper and brass parts that are not subject to impact load; 3. (): melting temperature-℃, the solder has low melting point and good fluidity, and can be brazed with silver flux for copper, brass, bronze and low zinc brass parts; 4. Melting temperature-℃, the solder is used as above. The addition of nickel increases the brittleness, but the fluidity is improved, and the weld is bright. It is generally used for copper and brass brazing. 5. (/BCuP-6): melting temperature-℃, low melting point, the solder can fill the joint gap in a large temperature range, and is mostly used for brazing copper and brass parts in refrigerators, air conditioners, motors and instrument industries; 6. (BCuP-3): melting temperature-℃, low melting point, the solder ductility and conductivity are improved, the fluidity is general, and it is suitable for brazing copper and brass parts with large gaps. 7, (/BCuP-7): melting temperature-℃, low melting point, the solder ductility and conductivity are improved, liquidity is better than B- , generally used for brazing gap larger copper and brass parts; 8. (BCuP-4): melting temperature-℃, low melting point, the solder has low melting point, good fluidity, and can braze joints with small gaps. It is generally used for brazing of copper and brass parts. Phosphor copper welding rod or silver phosphor copper welding rod is used for: connecting copper and copper alloy through capillary, welding carbon steel, copper and copper alloy, nickel chromium alloy and other ferrous and non-ferrous metal welding. It is applied to connect copper and copper alloys through capillary, and can also fill welds with small gaps. Phosphor copper electrode or silver phosphor copper electrode industrial applications: air conditioning and refrigerator industry: pipe connectors, valves, heat exchangers lead industry and household appliances: heating pipe/gas pipe, drainage pipe, household equipment power and electronics industry: rotor and motor, generator. Phosphor copper electrode or silver phosphor copper electrode is used for process: pretreatment thoroughly removes the connected connector parts, ensures that the connected area is free of dirt and oxides, completely removes burrs and right-angled edges. Phosphor copper electrode is composed of two parts: core and coating. The electrode is outside the metal core will be coating (coating) evenly, centripetal pressure coated on the core. Different types of welding rod, welding core is also different. The core is the metal core of the electrode. In order to ensure the quality and performance of the weld, the content of each metal element in the core has strict regulations, especially the content of harmful impurities (such as sulfur, phosphorus, etc.) should be strictly limited, which is better than the base metal. The metal core covered by the phosphor copper electrode is called the core. The core is generally a wire with a certain length and diameter. During welding, the welding core has two functions: one is to conduct welding current and generate arc to convert electric energy into heat energy; the other is to melt the welding core itself as filler metal and liquid base metal to form a weld.
