Great value for money
The price point is competitive for tin bronze. The only minor issue was the packaging could be slightly more robust for heavy items.

Reliable supplier for industrial parts
We have ordered multiple batches of the C200 copper tubes. Consistency in dimensions is impressive across all orders.

Excellent corrosion resistance
Using these in a marine environment and they are holding up very well against saltwater exposure. Highly recommended.

Good quality bronze
Solid material and good weight. We use these for slide blocks in our assembly line. Delivery was faster than expected.
Q: Is this material suitable for high-temperature applications?
A: Tin bronze maintains good mechanical properties up to approximately 250°C. For temperatures exceeding this, we recommend consulting our engineering team for alternative alloys.
Q: What are the exact dimensions for the ZQS5-5 block?
A: The ZQS5-5 block typically features a 5mm inner diameter, but custom lengths and outer diameters are available upon request. Please contact us with your specific drawing.
Q: What is the lead time for bulk orders over 500 units?
A: For bulk orders exceeding 500 units, the standard production lead time is 10-14 business days, plus shipping time depending on your location.
Q: Can these shaft sleeves be customized with oil grooves?
A: Absolutely. We offer CNC machining services to add oil grooves, holes, or specific tolerance fits based on your technical requirements.
Q: Do you provide material certification with the order?
A: Yes, every shipment includes a Mill Test Certificate (MTC) detailing the chemical composition and mechanical properties of the batch.
