Iron-Chrome-Aluminium Alloy Wire: Is a kind of high resistance electric heating alloy. the characteristic is: electric resistance is high, the weight is light, the price is low. But after being heated, plasticity bad, easy brittleness, not to be easy to weld and so on. If can be reasonably used, also be a kind of ideal electric heating material.
Available models: the alloy wire: 0.05mm--9.0mm.
the alloy mesh: 20mesh--200mesh. |
