| Parameter | Value | Benefit |
|---|---|---|
| Material Grade | ASTM B438 (C93200 equivalent) | Industry standard for durability |
| Hardness (HB) | 80 – 100 | Balances toughness and wear life |
| Tensile Strength | 250 MPa | Withstands high mechanical loads |
| Density | 6.4 – 7.0 g/cm³ (typical) | Optimal porosity for oil retention |
| Operating Temperature | -40°C to +200°C | Suitable for extreme environments |
| Surface Finish | As sintered / optional machining | Smooth operation with low friction |
Our heavy-duty copper bushings are designed to outperform standard bronze bushings in terms of load capacity and longevity. The precise hardness range of HB80-100 ensures that the bushing is not too brittle nor too soft, providing excellent resistance to deformation under cyclic loads. The tensile strength of 250MPa guarantees structural integrity even in high-stress applications such as hydraulic cylinders, heavy machinery pivots, and conveyor systems.
Additionally, the inherent self-lubricating property of sintered copper alloy reduces the need for frequent greasing, lowering maintenance costs and downtime. The material's compatibility with various lubricants and its ability to withstand contamination make it ideal for dirty or dusty working conditions.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a copper bushing and a bronze bushing?
A: Both are copper alloys. Our bushing is made of sintered bronze (copper-tin alloy) per ASTM B438, which offers excellent wear resistance and self-lubricating properties. The term 'copper bushing' is often used interchangeably in industry for these high-copper content products. -
Q: Can these bushings be used in high-temperature applications?
A: Yes, they can operate in temperatures ranging from -40°C to +200°C. For higher temperatures, please consult with our technical team for possible material adjustments. -
Q: Do you provide custom sizes?
A: Absolutely. We can produce bushings with custom inner diameters, outer diameters, lengths, and tolerances. Please provide your drawing or specifications for a quotation. -
Q: Are these bushings self-lubricating?
A: The sintered structure retains oil within its pores, providing inherent self-lubrication. For extended life, initial oil impregnation is recommended, and periodic re-lubrication depends on the application. -
Q: What is the typical lead time for orders?
A: For standard sizes, lead time is 7-15 days. For custom orders, it is typically 15-30 days depending on complexity and quantity. We offer expedited shipping options. -
Q: Do you have quality certifications?
A: Our factory operates under strict quality control systems. ISO certificates are available upon request. Additionally, our products comply with ASTM B438 standards, and we can provide test reports. -
Q: Can these bushings be used in marine environments?
A: Yes, the copper alloy offers good corrosion resistance to saltwater. However, for prolonged immersion, we recommend consulting with our engineers for specific alloy selection. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ is typically 100 pieces for standard sizes. For custom sizes, MOQ may vary. Please contact us for details.
