Electric resistance wire is also called heating wire. It is constructed from an alloy made from nickel (Ni), chromium (Cr), and often iron, primarily it is used as a resistance wire. It is widely used in home appliances and industrial heat treatment area. It's also included different types:NiCr Circular Wires: Cr20Ni80, Cr15Ni60, Cr20Ni35, Cr20Ni30, Cr30Ni70, Ni98.FeCrAl Circular Wires, Flat Wires:Ocr25Al5, Ocr21Al6, Ocr21Al4, Ocr23Al5, Ocr21Al6Nb, Ocr27Al7Mo2.

SINTON GROUP was founded in 2001,formerly known as the trade of electric heating and instrumentation, the group's total assets are RMB120 million, with 360 employees. In 2010, we had our own factory building and 5A office production environment, From trade mangement to self-built factory, office building production and sales of explosion-proof heater ,air duct heater,pipeline heater, drying oven, gas mould temperature machine, electromagnetic thermal oil furnace, thermal oil furnace and all kinds of heating elements.From embarrassingly short of money to group mangement model, at present, we integrated research, development, production and sales the products are exported to 12 countries in the world,Mainly Europe and America with strong product independent research and development capabilities and technological innovation. The work has obtained the explosion proof authentication,many patents authentication, the quality system authentication.
