Can replace silver brazing wire solve / steel welding / soldering copper and steel welding 威欧丁 201 Overview: Q201 is bearing an economical brazing alloy containing silver, brass and bronze can be used for brazing, and they of between dissimilar welding. And also applies to copper alloys and ferrous metals dissimilar brazing. Brazing for the bronze alloy can be obtained excellent strength and flowability. Brazing alloy deoxidizing element and zinc oxide can be reduced smoke generation. For brass or bronze and black brazing dissimilar metals can be obtained by forming a good, high-strength joint. Features: Triple-deoxy-performance; excellent flow properties; brazing process due to no glare, so the state of the pool of excellent visibility; color match with brass. Technical Specifications Operating Temperature ℃: ........................... 880 melting temperature (solid - liquid) ℃: ...... 870 ~ 900 Tensile strength MPa: ........................ 520 ~ 540 Resistivity μΩm: joint gap ........................ 0.07 mm: ........................... 0.2 Density kg / dm3: ........................... 8.4 applications a vehicle chassis and tubular parts, vehicle bronze shell connection supporting shaft manufacturing body, brass pipe forming tooth carbide cutting edges, use galvanized pipe and section Pretreatment region to be connected to ensure no contamination and oxides. 2, if the repair of cracks, to make the joint thickness is about 5mm and the shape is 60 ~ 90 ° of the "V" shaped connector. Preheat for small or thin-walled parts, usually do not require preheating; For large or complex shape parts the preheating temperature 200 ℃. 3, the operation process using oxygen flame brazing heating start site until dark red. Make sure not to melt the base metal material is very important, while not overheating otherwise undermine the performance of the joint. For low-flow connection member, may be in the form of butt joints, overlapping edges welded or "T" type connector (tight fit clearance), using the Q201-F solder in the joint region, and then heated until the co-solvent into a liquid, and then add a small amount of solder, heating was continued until the braze alloy to fill joints. Use a stiff brush child will get rid of the residue in water, then rinse until the residue is completely removed.
