QJ305 Pasty Silver-Based Brazing Flux

QJ305 Pasty Silver-Based Brazing Flux 　　QJ305 Pasty Silver-Based brazing flux produced by our factory was certified by relevant experts of Shanghai in March 14, 1991. Then, it was reported and introduced specially by some journalists such as Xin Min Evening Daily, Shanghai Vacuum Journal, Shanghai Science & Technology Daily, Heating and Ventilating Technology of Air Conditioners and Welding Research and Production, and won "recognition award" in " 92 New Technology and New Products Trade Fair of Nationwide Individually-Run Enterprises" held by State Commission of Science and Technology.

With a strong removal film capability, this product can improve brazed base metals’ wetTability and permeability and maintain its activation within 550～850℃. It can be applied to several brazing methods covering torch brazing, resistance brazing, induction brazing, high frequency brazing, furnace brazing and salt-bath immersion brazing, etc. Moreover, it can work together with silver-based brazing filler metals, copper-based brazing filler metals, copper-phosphorus-based brazing filler metals, brazing copper, copper alloys, steel, stainless steel and hard alloys, etc, offering a stable performance, good overflowing property and clean-cut appearance of brazing joint. Therefore, it features convenient application and repeatability without agglomeration for a long storage life. With more advantages than powder brazing flux, this kind of brazing flux can become a perfect alternative to foreign similar products.

QJ208 Environmental-Friendly Non-Corrosive Aluminum-Based Brazing Flux 　　QJ208 Environmental-Friendly Non-Corrosive Aluminum brazing flux is a hi-tech green product in the new century. Composed of chemicals including fluoride, it can be applied to several brazing methods such as gas furnace brazing or low-temperature torch brazing within 558～617℃. And, it can work together with aluminum-silicon-based brazing filler metals, brazing pure aluminum, aluminum-manganese alloys, etc., and present many advantages such as low melting point, rapid diffuse, strong permeability, clean-cut appearance free from residue, darkening and cleaning. At the same time, it is odorless, in noxious,

pollution-free and non-corrosive as well as resistant to moisture absorption and agglomeration during application. After the proven application of many units, it’s superior to domestic similar products, and, with its sediment less than foreign similar products, it can become an ideal alternative to the products of foreign peers.

516 Drilling Tools Alloys Brazing Filler

516 Drilling Tools Alloys Brazing Filler 　　516 drilling tools alloys brazing filler independently developed and produced by our factory is a quaternary alloy composed mainly of copper and nickel as well as subsidiary compositions including tin and manganese. Also, it contains some other microelements including Si, Fe, P, Zn and Re, etc. With various sizes of grains, it’s an ideal brazing filler metal used for large-scale drilling tools and other hard alloy sintering, presenting many features including good fluidity, high strength, resistance to erosion, impact and wear, etc. It won "recognition award" in "92′ New Technology and New Products Trade Fair of Nationwide Individually-Run Enterprises" held by State Commission of Science and Technology.
