Nickel based alloy Nichrome series
OUR ALLOY PRODUCT FEATURES
All our raw material is made from prime material, not recycle material. We have more than 25 years experience in manufacturing resistance heating alloys.
In the market, not all the NiCr alloys are with standard chemical composition and stable resistance. Professional and reliable is the soul of our business.
Product Description
INTRODUCTION OF PRODUCT
A Resistance Alloy used in electrical heating application. It is recommended for use in dry air applications up to 2150 degrees F with good hot strength. It is an alloy of nickel and chromium with high electrical resistance; used for resistance heating elements. Nichrome 80/20 is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is heated for the first time. Material beneath the wire will not oxidize, preventing the wire from breaking or burning out.
Applications:
These elements are commonly found in precision heating applications such as Medical Diagnostics, Satellite, and Aerospace
Electrical appliance industry
Ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements, cartridge elements
