We know that we only thrive if we can easily guarantee our combined cost competiveness and high-quality advantageous at the same time for C15760 Wire , Machining Beryllium , Cube2pb Threadlet , As an expert specialized within this field, we've been committed to solving any problem of high temperature protection for users.
Big discounting C17500 Strip - KINKOU158 copper alloy(Cu-Ni-Sn C72900) – Kinkou Detail:

* Achieve a combination of high rigidity and high strength. Can withstand dynamic impact loads. Can meet the most stringent requirements of static structural load and pressure. The thermal stress relaxation resistance is significantly better than beryllium copper alloy.
2. Excellent performance of anti-wear bearing, with the valuable performance of natural self-lubrication without friction pair seizure, it is a necessary material for the landing gear bearing of large aircraft, and is also the preferred friction component of oil well connecting rod and high temperature and high alternating load material.
*Turning performance is equivalent to easy turning brass alloy is very easy to process into complex components.
*Suitable for all kinds of acidic environment or salt water, high temperature corrosion resistance.
* Good welding performance.
*The electrical stability is significantly better than beryllium copper alloy. It does not generate magnetism and is a suitable material for high-temperature connectors and RF connectors.
*Non-toxic and harmless, environment-friendly materials.
