Short Circuit Ring/bar/ Shrink Ring Used in High Traction Motor

Advantages of Sirui bar and ring:
1. CuCr1Zr alloy melted in vacuum, gas content such as O , N and low melting point element such as Bi, Pb, S is very low which will benefit the strength of brazing joints.
2. Consistency of Cr and Zr content between each melting will guarantee tiny scattering of resistivity which will give better performance of motors.
3. Precision in linear and geometric dimension and ready for customers' assembly.
4. All processes are controlled by our own and no subcontract process.
