1. Product characteristics and usage：
High-resistance electrothermal alloy tools have electric and physical
characteristics such as high working temperature, long service life,
large resistivity, small resistance temperature coefficient etc. The
company produces wire of various specs to meet the design and requirements
in industrial resistance furnace, electric heating equipment, and
domestic electric appliances. It can also process resistance elements
of high temperature and high loading.
High-resistance electrothermal alloy is the most widely used electric
heating and resistance material of home and abroad at present. |
