Ordinary resistance wire deforms due to its softness when working, and its side length becomes soft, which affects the accuracy and speed of the cutting process. The iron-chromium-aluminum wire is hard, but brittle and easy to break. German original cutting wire will not become soft, will not deform at high temperature, and is durable. It is the best hot cutting steel wire.

The cutting wire imported from Germany has good surface oxidation resistance and high temperature strength. The maximum tensile strength of ordinary domestic heating wire is 780, and the imported cutting wire can reach 1800, which has good processing performance. The best cutting effect can be achieved by adjusting the temperature and cutting speed, and the type and density of the material will affect the cutting speed.
