Features

Profiled composite contact material is developed to meet the requirement of miniaturization, sensitivity and integration.
It has the following merits:
· Comprehensive advantages of various materials, applicable for multiple performance requirements.
· Good bonding strength, precise dimension, smooth surface and anti-wear properties.
· Weldable through spot welding with decent positioning and appearance as well as high electromechanical stability.
· economical consumption of precious metals.
Customized shapes and dimensions are available upon request.
