In the easy-to-understand "Brazing" series, we will explain "Brazing of Titanium." Titanium is a metal characterized by being "light," "strong," and "rust-resistant," with excellent corrosion resistance against seawater and saltwater. Due to its high strength and light weight, it is commonly used in aircraft and ships. Compared to stainless steel, titanium has a strong oxide film, which gives it superior corrosion resistance. To perform brazing, it is important to remove this strong oxide film; however, since oxygen and nitrogen in the atmosphere can affect the process, brazing is done in a furnace that isolates the air. Titanium brazing material is used. This brazing material can join at temperatures below titanium's transformation point, allowing for bonding without damaging the properties of the base material. We will provide a clear explanation with diagrams in the PDF materials.

Introducing "What is Brazing?" from the easy-to-understand "Brazing" series. "Brazing" is a technique that joins materials by melting the filler metal without melting the base material. "Welding" is a technique that joins materials by melting the base material. "Soldering" also joins materials by melting the filler metal, so the principle is the same, but "brazing" has a different melting point for the filler metal. In the mechanism of brazing, when there is an oxide film present, the molten filler metal does not spread, and residual substances like oil can hinder brazing. By removing the oxide film, the "brazing" can wet properly. 【Features】 ■ Thin plate joining and precision joining ■ Simultaneous joining of multiple points ■ Compatible with dissimilar metals and non-metals ■ High airtightness in joints ■ Minimal distortion due to overall heating *For more details, please refer to the PDF materials or feel free to contact us.

From the easy-to-understand "Brazing" series, we introduce "Atmospheric Brazing and Furnace Brazing." Brazing first requires the removal of the oxide film. By removing the oxide film, the "braze" can wet properly. "Atmospheric brazing" requires flux, which acts to remove the oxide film on the surface of the base material. "Furnace brazing" removes the oxide film on the surface of the base material by creating an atmosphere of hydrogen gas or vacuum inside a furnace that blocks the atmosphere. 【Features of Atmospheric Brazing】 ■ Easy to perform while visually monitoring ■ Localized heating is possible ■ Can perform insert brazing and surface brazing ■ Suitable for small-scale production *For more details, please refer to the PDF document or feel free to contact us.

High-pressure stainless steel plate heat exchangers feature a variety of selectable specifications such as filler materials, fins, and joints. The inner fins themselves serve as structural components, allowing them to withstand high pressure. Additionally, the fins act as secondary heat transfer surfaces, creating turbulence and demonstrating high thermal conductivity. They are ideal for CO2 heat pumps, CO2 refrigerant refrigeration equipment, evaporators for liquefied gases and general high-pressure gases, and refrigeration and freezing devices. There are two types of brazing: copper brazing, which offers excellent strength and can handle extremely low temperatures (-196°C), and nickel brazing, which has strong high-temperature strength and excellent corrosion resistance.
