With tungsten alloy for sale, it is one of the most brilliant China tungsten alloy manufacturers, welcome to buy and wholesale wolfram alloy and check the price of it with our factory. Tungsten Alloy                          W-La W-Mo alloys  We dope our tungsten with between 1.0 and 2.0 percent of lanthanum oxide (la2O3) by weight in order to improve its creep resistance and increase the recrystallization temperature. Our W-La is also easier to machine due to the finely distributed oxide particles in its structure. The electron work function of tungsten – lanthanum oxide is significantly lower than that of pure tungsten. Consequently, W-La is a popular choice for ion sources, lamp electrodes and welding electrodes.
