Easy-to-Understand Brazing Series: Brazing Method 1 - Atmosphere Brazing
Introduction to the characteristics of "hydrogen atmosphere" and "vacuum atmosphere."
We would like to introduce "Brazing Method 1 - Atmosphere Brazing" from the easy-to-understand "Brazing" series. Atmosphere brazing is classified into "hydrogen atmosphere" and "vacuum atmosphere." The "hydrogen atmosphere" uses hydrogen. The "vacuum atmosphere" performs brazing in a rarefied atmosphere evacuated by a vacuum pump. 【Hydrogen Atmosphere Features】 ■ It has a strong reducing power against metal oxides. ■ At high temperatures, low dew point hydrogen gas can reduce oxides of stainless steel, iron, chromium, copper, nickel, and others. ■ Oxides of metals containing titanium and aluminum cannot be reduced. ■ The dew point refers to the moisture content in hydrogen gas, and the lower it is, the higher the reducing power. ■ Hydrogen has good thermal conductivity and is environmentally friendly. *For more details, please refer to the PDF materials or feel free to contact us.
