(Common Name: CuNi45, NC50.Cuprothal, Alloy 294, Cuprothal 294, Nico, MWS-294, Cupron, Copel, Alloy 45, Neutrology, Advance, CuNi 102, Cu-Ni 44, Konstantan,constantan.)

OhmAlloy049 is a copper-nickel alloy (Cu56Ni44 alloy) characterized by high electrical resistance, high ductility and good corrosion resistance. It is suitable for use at temperatures up to 400°C

Typical applications for OhmAlloy49 are temperature-stable potentiometers, industrial rheostats and electric motor starter resistances.

The combination of negligible temperature coefficient and high resistivity makes the alloy particulary suitable for the winding of precision resistors.

OhmAlloy049 is manufactured from electrolytic copper and pure nickel. In finer wire sizes the alloy is designated as OhmAlloy49TC(Thermocouple).

Palisade Fence

Palisade fencing, as effective security fencing, is the widest used type in the UK. The forbidding appearance, inherent strength and high damage resistance make the palisade fencing one of the best choices of premise protection.
Designed with smooth surface, rigidity structure, sharp prongs and narrow pale spacing, the palisade fences are normally considered to be difficult even impossible to climb, straddle, grab and gain foot-hold. Thereby, it effective deters would to be intruders and trespassers, protects your assets, office and factory from damages.

Palisade pales are available in D section, W section and angle steel types. All the pales are bolts to two horizontal palisade rails as standards. Once the fence height is over 3 meters, one more palisade rail is needed to maintain the integrity for high security.
