Phosphor bronze wire rod Wei Ouding low phosphor 202A Note: There are many companies and individuals theft of my company's picture and text information, foreign sales Wei Ouding special welding materials, many users blindly take a lot of detours, and the use of who suffer a certain amount of economic loss, hereby tips! Weiou fake provenance more places are: Hebei Xingtai, Hebei Tangshan, Hebei Shijiazhuang, Zhejiang, Fujian. At the time of purchase, please contact the dealer to see whether my company and our company. Overview Weiou Ding Wei Ouding 202A 202A three-phase low-temperature copper alloy Cu-Ag-P brazing alloys, high silver content. Connection of copper and copper alloy by capillary action. Component contains silver, increasing the flowability of the solder, improves the mechanical strength of the joint. Excellent joint tightness. Wei Ouding 202A melting temperature mechanical and physical properties (solid - liquid) ℃: 645 ~ 770 Working Temperature ℃: 710 joint gap mm: 0.1 ~ 0.2 Density g / cm3: ~ 8.8 Tensile strength MPa: 400 ~ 500 resistivity μΩm : 0.22 Tensile strength MPa: ~ 245 (20 ℃) ??Shear strength MPa: ~ 175 (20 ℃) ??Wei Ouding 202A application to connect copper and copper alloy by capillary action, or you can fill the gap larger weld. Wei Ouding 202A air conditioning and industrial applications refrigerator industry: pipe joints, valves, heat exchangers, plumbing and household appliances: heating tube / pipe, drains, household electrical and electronic equipment industry: rotors and motors, generators Wei Ouding 202A Pretreatment of the elimination of the use of connected joints, make sure the area is to be connected without fouling and oxides, completely remove the burr, angled edges. No need to use a co-solvent for copper, copper alloy is recommended for 201-F Wei Ouding flux welding. Wei Ouding 202A operating process using neutral flame, furnace, resistance heating or induction heating method brazing. For flame heating: heating the solder tip and then preheat the joint area until a co-solvent or melt the base metal into a dark red. Continuously moving the flame, in the direction of the joint to melt the solder. Solder will naturally flow to the region with the highest temperature. Wei Ouding 202A Notes: 1. Do not overheat or directly heating the solder. 2, to make the workpiece was slowly cooled to 100 ℃. Rinse with hot water to remove residue of a flux, increasing immersion time, or using a brush to remove residue of a flux in cold water. If not completely remove residue of a flux, will result in corrosion of the workpiece. 3, do not inhale smoke; 4, to ensure the completion of brazing in a fully ventilated environment
