The selection of appropriate materials and precise control over the production process are essential for ensuring the high quality and performance of lead-free brass bushings.
- Quality Control: Stringent quality control measures are essential during the production of lead-free brass bushings. Key factors such as dimensions, hardness, wear resistance, and corrosion resistance are closely monitored to ensure the bushings meet the required specifications. Tests for compliance with health and safety standards are also conducted, particularly for plumbing applications.Some typical quality tests include:
- Dimensional inspection to ensure proper fit.
- Hardness testing to confirm the material’s resistance to wear.
- Corrosion testing to evaluate long-term durability in various environments.
C46400 and C69300 are both lead-free brass alloys, each with specific properties and applications suited for various industrial needs.
C46400 Naval Brass
C46400, also known as naval brass, is a copper-zinc-tin alloy that contains approximately 59% copper, 40% zinc, and about 1% tin. This alloy is notable for its:
- Corrosion Resistance: The addition of tin enhances its resistance to corrosion in seawater and other mildly aggressive environments. It also provides resistance to dezincification, a process where zinc is leached out from the alloy, which can compromise its structural integrity.
- Mechanical Properties: C46400 exhibits good tensile strength (55,000 to 88,000 psi) and yield strength (up to 66,000 psi), making it suitable for demanding applications. Its elongation at break is around 50%, indicating good ductility.
- Applications: Commonly used in marine applications such as propeller shafts, turnbuckles, and various fittings. It is also found in valve stems, heat exchangers, and other components requiring durability and resistance to wear and fatigue.
C69300 Lead-Free Brass (ECO BRASS
C69300 is a high-performance lead-free brass alloy that has gained widespread use across various industries, especially due to its excellent mechanical properties and compliance with stringent health regulations. This alloy is considered an environmentally friendly alternative to traditional brass alloys, offering similar performance without the harmful effects of lead.
Chemical Composition of C69300
C69300 is primarily composed of:
| Element | Composition (%) |
|---|---|
| Copper (Cu) | 73.0% – 77.0% |
| Silicon (Si) | 2.7% – 3.4% |
| Phosphorus (P) | 0.04% – 0.15% |
| Lead (Pb) | Maximum 0.09% |
| Zinc (Zn) | Remainder |
| Nickel (Ni) | Maximum 0.10% |
| Manganese (Mn) | Maximum 0.10% |
| Iron (Fe) | Maximum 0.10% |
The key feature of C69300 is its extremely low lead content, with a maximum of 0.09%. This makes it an ideal choice for applications involving drinking water and other food-grade environments, ensuring compliance with health and safety standards.
Mechanical Properties of C69300
C69300 is known for its robust mechanical properties, which make it suitable for a wide range of applications:
| Diameter Range | Tensile Strength | Yield Strength | Elongation |
|---|---|---|---|
