### 1. **Classification by Filler Metal Composition:**
- **Pure Iron-Based Brazing Alloys:**
These alloys consist primarily of iron, with small amounts of other elements added for specific properties such as improved flow, wetting, or corrosion resistance.
- **Iron-Nickel (Fe-Ni) Alloys:**
These alloys contain significant amounts of nickel, which enhances the alloy's strength, ductility, and resistance to corrosion. They are often used in high-temperature applications.
- **Iron-Chromium (Fe-Cr) Alloys:**
Chromium is added to improve the oxidation resistance and hardness of the brazed joint. These alloys are suitable for applications requiring high wear resistance.
- **Iron-Manganese (Fe-Mn) Alloys:**
Manganese is added to increase the strength and toughness of the brazed joint. These alloys are often used in structural applications.
- **Iron-Silicon (Fe-Si) Alloys:**
Silicon is added to improve the fluidity and wetting of the filler metal. These alloys are commonly used in electrical and electronic applications due to their good electrical conductivity.
### 2. **Classification by Brazing Temperature:**
- **Low-Temperature Iron Base Brazing:**
This involves brazing at temperatures below 900°C (1652°F). It is suitable for joining materials that have lower melting points or are sensitive to high temperatures.
- **High-Temperature Iron Base Brazing:**
This involves brazing at temperatures above 900°C (1652°F). It is used for joining materials that can withstand higher temperatures and require stronger joints.
