Nickel chromium alloy wire/NI70Cr30/
Product Introduction
After many experiments, we have successfully ensured that the cost of our SIC heater elements, thermostat for chiller, Micro thermal switch is reduced under the premise of product performance meeting the standard. We wish we could establish sound business relationships with all customers from at home and abroad on the basis of mutual benefits. Focusing on the global market, building an international brand, continuously improving our quality level, and maximizing customer profits are our constant commitment and eternal pursuit. From raw material procurement to finished product completion, we adopt full independent management, which makes the product cost has incomparable cost advantage in similar products. At any time, we can not stop improving the quality of products and services. The requirements of users are always reasonable, and the dissatisfaction of users is the driving force of our improvement work.
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
