Material performance is the basis for terminal normal force, which affects the ECR value. AUPINS contact terminals are able to be made in brass, phosphor bronze, or customized materials. The yield and tensile strength, hardness, elongation, and conductivity-thermal conductivity of material are most important factor to make choice. In addition, the plating is a significant factor in ECR value. High-level multi-layer plating technology is applied to ensure product precision. AUPINS team will guarantee the best competitive price to meet the customer's different requirements.
