Constantan Copper Nickel 40 Wire / Flat Wire
Product Introduction
The soft heat heating pad, Outdoor Heating Pad, Thermostat Sensor Temperature Switches is independently developed by our's own R&D team since we owning industry-leading core technology. The corporate culture system with the core concepts of self-improvement, integrity, truth-seeking and innovative spirit has been established. We are forming a passionate core team to create disruptive products together.
Description
According to your requirements, we will produce the profiles and mechanical property of the electirc heating element alloy strip to meet your needs.In process of using our precision wire, you will find that our product saves your plenty of time and reduces your costing abviously. We also have special die and advanced cold rolling process to shape, and deliver by coils or bundles, the tolerance up to 0.025mm.
By the process of cold rolling, we realize the mechanical property as you wish, such as tensile strength, hardness, ductility and elongation
