### 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.
The York Center Fire Protection District, part of MABAS Division 12, serves an area of 5 square miles that includes unincorporated sections of Villa Park, Lombard, and Oak Brook, as well as the community of York Center and parts of Oak Brook Terrace. The department operates from a single fire station, staffed by 2 full-time and 68 part-time firefighters who are dedicated to protecting the local community.
Their fleet consists of a variety of specialized vehicles, including an E-ONE Hush pumper with a rear-mounted engine, a Pierce pumper, a Pierce heavy rescue unit, two Medtec ambulances, and a US Tanker built on a Freightliner M2112 chassis. These units are essential for responding to a wide range of emergencies, from fires to medical calls.
One notable piece of equipment is the 1993 E-ONE Hush pumper, which was originally painted in white and lime green. This rear-engine pumper features an enclosed top-mounted operator’s console protected by an extended vista cab. It is equipped with a 1,500-GPM pump and a 750-gallon water tank. Although the original green color has been replaced with red, the vehicle remains in service with the department. This particular unit is part of the Larry Shapiro collection and showcases the district's long-standing commitment to safety and service.
Another key asset is the US Tanker, which plays a vital role in supporting firefighting operations by transporting large quantities of water to remote or high-risk areas. Its presence highlights the department’s ability to respond effectively to various emergency situations, ensuring the safety and well-being of residents in the region.
Iron base brazing is a category of brazing processes that use filler metals with iron as the primary element. This type of brazing is widely used in various industrial applications, particularly where high strength and good corrosion resistance are required. Below is a classification and brief introduction to iron base brazing:
