Product Introduction

W-Ni-Fe alloy bar

W-Ni-Fe alloy bar is an alloy based on tungsten (about 90 ~ 98%) and adds nickel, iron, copper, or other groups of metals, and the proportion is generally 17.0 ~ 18.5.

W-Ni-Fe alloy bar preparation process

The key to the process of the W-Ni-Fe alloy bar preparation process is the sintering process. The sintering temperature is 1400^1600C, and the liquid phase is generated, which is conducive to the density of the alloy. The W-Ni-Fe alloy bar after sintering can reach the theoretical density More than 99%. The sintering products can also use thermal treatment to improve plasticity and strength, and then perform pressure processing, and its mechanical properties are significantly improved.

Application of W-Ni-Fe alloy bar

The W-Ni-Fe alloy bar is particularly suitable for car quality components. Drilling one or more caves with a diameter of 25/64 or larger diameter on the module, and then filling in the tungsten alloy cylinder required to be filled in. Then insert a 3/8 -inch long rod into the hole. W-Ni-Fe alloy bars can also be processed into military products, molds, and various weights, such as speedboats, vehicle weight, aircraft weight, helicopter weight, ship weight, tank weight, etc. Essence Generally, W-Ni-Fe alloy bars can be used in the field of military industry and can also be used as molds and various weights.
