The X-ray tube selects different anode targets according to the power level. Due to the low power requirements of the X-ray tube for security inspection, industrial non-destructive testing, dental diagnosis, etc., all of them adopt fixed anode targets. Our company manufactures the anode target through X-ray tube obtained by tungsten target and oxygen-free copper back casting (the stationary anode target for X-ray tube of our company is obtained by back casting method from tungsten target and oxygen-free copper). The joint surface of tungsten and oxygen-free copper does not have holes, and is tightly combined to have good heat dissipation.
