C37000 is a specific type of leaded brass, commonly referred to as Free Machining Brass or Clock Brass. It is an alloy predominantly composed of copper, with significant additions of lead and minor amounts of iron and other elements.
This particular brass grade is highly valued for its excellent machinability, making it a preferred material for manufacturing components that require precise shaping and intricate designs.
Chemical Composition of C37000
The material C37000 is defined by its precise chemical makeup, which gives it its characteristic properties. The typical composition ranges are as follows:
| Element | Minimum (%) | Maximum (%) |
|---|---|---|
| Copper (Cu) | 59.00 | 62.00 |
| Lead (Pb) | 0.80 | 1.50 |
| Iron (Fe) | - | 0.15 |
| Total Others | - | 0.40 |
Key Characteristics and Applications
The presence of lead in C37000 is crucial, as it acts as a chip breaker during machining, leading to very short, easily removable chips. This significantly reduces tool wear and allows for higher machining speeds, resulting in:
- Superior Machinability: Known for its ease of cutting, drilling, and shaping, which is essential for mass production of small, complex parts.
- Good Strength and Durability: While primarily chosen for machinability, it still offers adequate mechanical strength for many applications.
- Corrosion Resistance: Like other brass alloys, it exhibits good resistance to corrosion in various environments.
Due to these properties, C37000 is widely utilized in industries requiring high-volume production of precision components. Common applications include:
- Clock and Watch Components: Its original designation as "Clock Brass" highlights its suitability for intricate gears, pinions, and other parts in timepieces.
- Machine Parts: Used for various machined parts in machinery where accuracy and ease of fabrication are paramount.
- Fittings and Connectors: Ideal for manufacturing plumbing fittings, electrical connectors, and other hardware.
- Musical Instruments: Can be found in certain parts of brass instruments.
In summary, C37000 is a specialized leaded brass alloy distinguished by its precise copper and lead content, engineered for optimal machining performance in demanding manufacturing processes.
