Ni80Cr20 is a nickel-chromium alloy (NiCr alloy) characterized by high
resistivity, good oxidation resistance and very good form
stability. It is suitable for use at temperatures up to 1200°C,and
hold a superior service life compared to Iron chromium alumium
alloys.

Packaging & Shipping
Packaging: Products are generally supplied in standard cardboard
boxes, pallets, wooden boxes.
Special packaging requirements can also be accommodated. (also depend on
the customers' requirements) For the Thermal spray wires, we pack
the wires on spools. Then put spools into cartons, Then put the
cartons onto pallet.
Shipping: We cooperation with many logistics company, We can
provide express, sea transportation, air transportation, and rail
way transportation based on customers' requirement.
