4. Typical Applications
Resistohm 135 is a ferritic alloy of the FeCrAl family, which can be used as
heating element of resistance up to 1200°C.
Resistohm 135 must be used in a dry environment in order to avoid rust because
this is not a stainless alloy.
Elements realised in Resistohm 135 have an excellent life time in a
sulphurous environment, and particularly when atmosphere is also
oxidizing.
Resistohm 135 is normally used in top cookers with ceramics, pottery furnaces
elements, and tubular elements.
Because of its resistance to carbonaceous atmospheres, Resistohm
135 is chosen for the production of cigarette lighters and fuel
burners elements.

WHY CHOOSE US?
All our raw material is made from prime material, not recycle
material. We have more than 10 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.
1) We achieve consistent production from smelting to complete
products, we are able to supply satisfactory
products.
2) We have has the world's advanced level of German ALD - VIDP1000
- 8000KG vacuum induction furnace and
wire drawing machines from Japan.
3) With our skilled spooling knowhows, we have successfully
magnified the take - up weight on spool. For
example, even a superfine wire of 0.04 mm in diameter can be wound
and shipped on a 3 - 4 kg bobbin, thus
immediately contributing to your productive efficiency.
4) In order to prevent a wire from loosening, we have introduced a
developed tension controlled systems into our
ake - up machine and respooling machine.
We think you can anticipate smooth despooling.
