Silver solder, copper solder, nickel solder, etc.! Introducing the characteristics and selection criteria of various solder materials.
From the easy-to-understand "Brazing" series, we introduce "Types of Filler Metals and How to Choose Them." There are many types available, including silver solder, copper solder, copper alloy solder, nickel solder, active silver solder, and titanium solder. The criteria for selecting filler metals are "compatibility with the base material," "melting point," "brazing strength," "corrosion resistance and heat resistance," "cost-effectiveness," and "shape of the filler metal." 【Types of Filler Metals】 ■ Silver solder, copper solder, copper alloy solder ■ Active silver solder, titanium solder, aluminum solder ■ Nickel solder, iron blaze, ■ Gold solder, palladium solder *For more details, please refer to the PDF materials or feel free to contact us.

basic information
**Characteristics of Various Filler Materials (Partially)** ■ Silver Solder - Good workability at low temperatures and strong strength - Easy to process and available in various shapes ■ Copper Solder - Good wetting on iron-based substrates and strong strength - Inexpensive, but has a high melting point, so it is used for furnace brazing ■ Copper Alloy Solder - Phosphor bronze solder contains phosphorus to lower the melting point, suitable for copper and copper alloys (However, it is not suitable for iron-based substrates) ■ Nickel Solder - High strength at elevated temperatures, excellent oxidation resistance and corrosion resistance - Used for furnace brazing of stainless steel *For more details, please refer to the PDF materials 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.
