Titanium, ceramics, cemented carbide, and more! We will provide detailed information on the properties of materials and key points for brazing.
We would like to introduce "Soldering" series, specifically "Solderability to Various Materials 2 - Titanium, Ceramics, and Cemented Carbide Edition." "Titanium," which has about 60% of the density of iron, is resistant to rust and strong against seawater, and soldering below the transformation point is recommended. For "ceramics," which have high strength at high temperatures, as well as corrosion resistance, wear resistance, and oxidation resistance, we recommend the "Reactive Metal Method" for soldering with metals. [Points for Titanium Soldering] - Removal of the strong oxide film is necessary - Reacting with nitrogen, oxygen, hydrogen, and carbon increases hardness and decreases toughness - Soldering below the transformation point (883°C) is recommended - Atmospheric soldering is difficult - Inert (Ar) gas or vacuum atmosphere soldering is preferable *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Points of Soldering Ceramics】 - There are two methods for soldering ceramics and metals: "Active Metal Method" and "Metallization Method." - The Active Metal Method involves directly soldering the base material with active solder. - The Metallization Method involves applying Mo-Mn powder to the base material, followed by nickel plating, and then soldering with silver. - When soldering ceramics and metals, pay attention to the difference in thermal expansion coefficients. *For more details, please refer to the PDF document or feel free to contact us.*

Company information
"Brazing" is a technique that involves flowing "molten metal filler" between base materials and cooling it to join them. The base materials and the filler are firmly bonded at the atomic level. 【Brazing is a familiar joining technology】 Brazing is used in parts for automobiles, air conditioners, gas water heaters, tools, and more. It is widely useful in fields such as machining and pipe processing. 【Advantages of Brazing】 ● Can join thin sheets and achieve precise connections ● Can join multiple points simultaneously ● Can join dissimilar metals and non-metals ● Can create complex shapes that cannot be made through cutting or grinding ● Can achieve high airtightness in joints While "welding" is a technique that joins materials by melting the base material, "brazing" is a technique that joins materials with little to no melting of the base material, making it suitable for joining delicate parts such as small items and thin sheets.
