The magnetic type of high specific gravity tungsten alloy is mainly determined according to its chemical composition and heat treatment method. In general, high specific gravity tungsten alloys have the following magnetic properties:
1. Non-magnetic: Tungsten-nickel-iron alloy (WNiFe), tungsten-copper alloy (WCu) and other alloys are non-magnetic materials at room temperature.
2. Low magnetism: Alloys such as tungsten-iron-copper alloy (WCuFe) have low magnetism at room temperature, but exhibit strong magnetism at high temperatures.
3. High magnetic properties: alloys such as tungsten-iron-cobalt alloy (WNiCo), tungsten-iron-vanadium alloy (WNiV), tungsten-iron-silicon alloy (WSiFe) and tungsten-iron-titanium alloy (WTiFe) have Highly magnetic.
It should be noted that the magnetism of high specific gravity tungsten alloy is not stable, it is affected by factors such as elements added to the alloy, alloying degree, heat treatment method, etc. Therefore, it is necessary to select a suitable high specific gravity tungsten alloy according to specific needs during application type.
