Problems solved by technology

Because the electrothermal film cannot be closely integrated with the outer surface of the appliance or pipeline, and its heat conduction efficiency is not high enough, the red hot temperature of the electrothermal film itself is very high.
Therefore, the electric heating film made of this material has limited service life and low thermal efficiency.

Description

technical field [0001] The invention relates to the technical field of alloy material preparation, in particular to a novel alloy material used for electric heaters. Background technique [0002] At present, electric heating appliances, such as electric heating film pots, electric radiators and the like or pipeline water heaters, are developing rapidly. The electrothermal film on the electric heating appliance is generally a conductive film made of materials such as chloride. This electrothermal film can not be closely integrated with the outer surface of the appliance or pipeline, and its heat conduction efficiency is not high enough to make the blazing red temperature of the electrothermal film itself very high. Therefore, the electric heating film made of this material has limited service life and low thermal efficiency. Contents of the invention [0003] In order to overcome the above-mentioned problems of existing electric heating materials, the object of the presen...
