Iron Chromium Aluminium resistance heating alloys |
|
|
| |
|
 Chrom alloys can be furnished either bright or oxidized in wire (0.015÷5.00 mm. diam.) and ribbon (0.30÷6.00x0.05÷2.00 mm) form.
All these alloys are ferromagnetic.
Companies can choose from a full range of Chrom alloys for all their electrical resistance requirements.
Our experienced technical staff can offer help and guidance as to the best alloy for your particular
need from both a technical and economical aspect.
Special “tailor made” alloys for that special
application can also be produced.
