Copper has high thermal conductivity and is used in cooking utensils, thermal conduction components, and heat exchangers. It also has excellent castability and workability, and its beautiful surface appearance makes it a material used for art and decorative items. This is a booklet that clearly explains the appropriate joining method for copper products, "Brazing of Copper Components." Currently, we are offering a free basic knowledge booklet to the first 100 applicants. 【Overview】 ■ Characteristics of Copper ■ Main pure copper materials used as base materials and their characteristics ■ Other copper alloys ■ Classification of copper joining methods ■ Main brazing materials and temperature ranges used for brazing copper components ■ List of main silver brazing materials ■ List of main phosphorus copper brazing materials ■ List of main nickel brazing materials ■ Considerations for selecting brazing methods for each brazing material ■ About Shinwa Joytec Center Co., Ltd. *For more details, please check the information through [Request for Materials] or [Catalog Download].

"Shinwa SG Bronze" is ideal for brazing stainless steel, tool steel, and copper alloys. It is also suitable for joining dissimilar alloys such as copper and nickel alloys. ≪Features≫ - It provides good fluidity and results in a shiny welded metal. - The inclusion of Ni (nickel) and Si (silicon) reduces the combustion of zinc, helping to minimize the occurrence of blowholes and pinholes. - We can accommodate requests for irregular shapes (rings, semicircles, etc.). *For more details, please download the catalog or contact us.

This is a spatter adhesion prevention agent that is optimal for soft steel, stainless steel, and high-strength steel, demonstrating powerful effects. 【Features】 ■ Stable properties that do not separate or settle ■ Does not contain silicon, so it does not impair paintability ■ Does not adversely affect the mechanical properties of the weld ■ A versatile, water-soluble type suitable for steel materials other than aluminum *For more details, please download the catalog or contact us.

We will respond with mass production level quality and quick delivery even for prototypes and small lot products.

In the upcoming 5G era, a challenge is how to suppress the "heat generation" associated with the high-speed processing of machines. To address this, the complexity of heat exchangers and various components is being emphasized, and the technology of "brazing" will play a significant role in these areas. We are currently offering a technical document that clearly explains the appropriate joining method "brazing" for products that require compactness and high performance. [Overview of Contents] ◆ Basic principles of brazing ◆ Detailed explanation of brazing - Reasons why a strong joint can be achieved when "brazing" fills the joint gap - Capillary phenomenon and optimal gap for brazing - Wetting of the brazing material due to the reducing action of the base material and brazing filler - Four major elements of brazing ◆ Introduction to main brazing materials ◆ Vacuum brazing - Advantages of vacuum brazing - Disadvantages of vacuum brazing - Vacuum brazing process - Heating conditions for vacuum brazing - Guide for selecting brazing materials based on base material combinations *For more details, please check the information through [Request for Materials] or [PDF Download].

With the development of communication networks and the advancement of devices, the challenge is how to suppress the "heat generation" that occurs during high-speed processing. To address this, the "complexity" of heat exchangers and various components is required, and the technology of "brazing" becomes a joining technique that plays an active role in such areas. We are currently offering a technical document that clearly explains the appropriate joining method "brazing" for products that require compactness and high performance. [Overview of Contents] ◆ Basic principles of brazing ◆ Detailed explanation of brazing - The reason why strong joints can be made by the flow of "brazing material" into the joint gap - Capillary phenomenon and optimal gap for brazed joints - Wetting of the brazing material due to the reducing action of the base material and brazing material - The four major elements of brazing ◆ Introduction to main brazing materials ◆ Vacuum brazing - Advantages of vacuum brazing - Disadvantages of vacuum brazing - Vacuum brazing process - Heating conditions for vacuum brazing - Guide for selecting brazing materials based on base material combinations *For more details, please check the information through [Request for Materials] or [PDF Download].

The OWELD company's "Hydrogen Burner Brazing Device" is a hydrogen burner that boasts output comparable to that of a gas burner. By not using combustible gases such as acetylene, it achieves zero CO2 emissions and significantly reduces the running costs (gas fees) that were incurred each time it was used. Additionally, it can be installed in a space-saving manner as it eliminates the need for cumbersome gas cylinder exchanges or the installation of supply piping from outdoor supply tanks. Hydrogen and oxygen are generated on demand, so there is no need to store them in tanks, allowing for safe usage. 【Features】 ■ Contributes to CO2 reduction and carbon neutrality ■ Lower running costs compared to conventional gas burners ■ Higher safety due to not storing gas in tanks ■ Provides a constant and stable flame of hydrogen and oxygen *For more details, please refer to the PDF document or feel free to contact us.
