Guangzhou Youyan Welding Materials Technology Co., Ltd. (hereinafter referred to as "Guangzhou Youyan") was restructured in January 2021 in the Sino-Uzbekistan Welding Research Institute of the Guangdong Academy of Sciences. It is a joint-stock enterprise with the Sino-Uzbekistan Welding Research Institute's Brazing Materials Achievement Transformation Department as the team and the Sino-Uzbekistan Welding Research Institute as the shareholding. Specializing in the research, development and production of advanced brazing materials such as aluminum base, copper base and nickel base, providing brazing technical support and high-end brazing material customization services. The team successfully developed non-corrosive potassium fluoaluminate flux (Noclock Flux) and powdery aluminium-silicon alloy (Al88-Si12) brazing materials in 1993, breaking the monopoly of foreign products in this market at one stroke. Its materials and technology have been granted multiple authorized patents, and has been awarded provincial and ministerial awards for many times. Its product quality is at the advanced domestic or international level. Research field of the team: New materials - special functional materials. Research/service direction: R&D, production and application of aluminum base, copper base and nickel base brazing materials; Brazing materials are divided into flux and filler metal, which are used together; Brazing materials are in the form of powder, paste, filiform, ring and sheet; And provide brazing technical support and high-end brazing material customization services.
FA-A corrosion-free potassium fluoaluminate for automotive aluminum radiator with completely independent intellectual property rights is widely used in the brazing of water tanks, air conditioners, oil coolers, intercoolers and other components in the automotive cooling system, including spraying process and electrostatic spraying process. The product performance has reached the international advanced level.
Electric small household appliances are mainly composed of the pot body, base, temperature controller and heating plate components. By developing new brazing materials that can realize intelligent feeding and green production - aluminum solder, aluminum solder paste and composite aluminum solder wire, our company replaces the original powder aluminum solder and aluminum solder, assists in the development of peripheral automation equipment, realizes the automatic distribution, assembly and welding of heating plate components, and lays the foundation for the automatic green production of electric kettle.
The aluminum-based and copper-based brazing materials independently developed by our company have been widely used in the double-bottom brazing of kitchen utensils since 1993, successfully replacing imported products, providing stable and reliable supply guarantee for many large domestic kitchen utensils enterprises, and effectively reducing procurement costs and time costs. The products are of excellent quality and sell well both at home and abroad, and have won the honorary titles of "Excellent New Products of Guangdong Province" and so on.
The water-based and oil-based nickel-based solder pastes independently developed by our company are widely used in the manufacturing fields of electric heating appliances, auto parts, precision hardware, etc., especially for stainless steel products with dense welding spots and complex and diverse welds, which have good brazing performance. The product series includes most models of the American Welding Society (AWS) BNi-1 to BNi-13, as well as non-standard customized products independently developed by our company for three-way catalytic converter, EGR, water heater heating pipe and other applications. Meet the personalized needs of customers to improve the high-temperature oxidation resistance, fatigue resistance, high strength and other properties of products after welding.
