The previous versions of this document and the documents it replaces are as follows. ---First published in.1992 as GB/T 13815-1992 and first revised in.2008 as GB/T 13815-2008; ---This is the second revision.IntroductionAluminum-based brazing alloys are key connecting materials for core components of the manufacturing industry. They have the advantages of low brazing temperature, good fluidity, easy processing, excellent crack resistance and With the increasing awareness of energy conservation, emission reduction and green environmental protection, "replacing copper with aluminum" in lightweight structural design is in line with the national sustainable development Therefore, aluminum-based brazing filler metals are widely used in the fields of electronics, petrochemicals, aerospace, refrigeration, etc. The material is often used for brazing connection of aluminum and aluminum alloy, aluminum alloy and other metals. Its quality directly affects the performance and connection quality of the product. The formulation of its product standards is of great significance. Brazing is one of the key basic technologies in the manufacturing industry. As the manufacturing industry develops towards green, intelligent and high-end directions, the demand for brazing materials The technology has put forward new demands and higher challenges. Conventional solid brazing materials such as wire and sheet can no longer meet the market demand. The new composite brazing materials such as flux core brazing materials, flux coated brazing materials, paste brazing materials, etc. have great development potential. "Brass Filler Metals" is a universal product standard for brazing filler metals and is intended to consist of the following parts. --- Part 1.Solid brazing filler metals. The purpose is to specify the requirements for solid aluminum-based brazing filler metal products for brazing. --- Part 2.Flux-cored brazing filler metals. The purpose is to specify the requirements for flux-cored aluminum-based brazing filler metals for brazing. --- Part 3.Coated brazing filler metals. The purpose is to specify the requirements for coated aluminum-based brazing filler metal products suitable for brazing. --- Part 4.Paste brazing filler metals. The purpose is to specify the requirements for paste aluminum-based brazing filler metal products suitable for brazing. GB/T 13815 was first independently formulated in.1992 and revised in.2008.Its technical content has always been at the international leading level. GB/T 13815-2008 has been issued and implemented for more than ten years. During this period, the preparation technology of aluminum-based brazing alloys in my country has been improved and new products have been developed and applied. It has played an important role in promoting the use of high-quality key connections in basic manufacturing equipment such as lightweight structures, home appliances, refrigeration and other industries. Materials-aluminum-based brazing filler metals have a more significant significance. At present, with the rapid progress of non-ferrous material research and metallurgical technology, research and development New products have put forward higher requirements for intelligence, functionality, and miniaturization. This revision of GB/T 13815 focuses on the technical requirements for high-end equipment manufacturing and adds more miniaturized foil and strip solder. Dimensional indicators to meet the needs of integrated, functional and miniaturized products. With the changes in solder composition and analysis technology, some The main elements, impurity elements content and melting temperature range of the solder chemical composition are added, and new types of solder for engineering applications are added. The chemical composition requirements are more reasonable, and the ingredient list is more in line with the product's own requirements, thereby promoting the improvement and quality of my country's aluminum-based solid brazing filler metal products. improvement.

The first chemical element symbol Al represents the aluminum solder. For basic components, the nominal mass fraction of Al shall be indicated after the element symbol and the value shall be an integer. c) The symbols of other elements are arranged in descending order according to their mass fractions. When several elements have the same mass fraction, they are arranged in order of their atomic mass fractions. Arranged in ordinal order. d) Elements with a mass fraction of less than 1% do not need to be listed in the model. If an element is a key component of aluminum brazing filler metal and must be listed, The chemical element symbol is indicated in brackets. 4.2 Model Examples The comparison of aluminum solder types in this document and other relevant standards is shown in Appendix A. Examples of aluminum solder types in this document are as follows. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 13815.1-2025_English be delivered?Answer: Upon your order, we will start to translate GB/T 13815.1-2025_English as soon as possible, and keep you informed of the progress.
